Standard OBD-II Diagnostics

The MX+ handles the common diagnostic functions expected from a modern OBD-II scanner.

Using the included OBDLink application or compatible third-party software, you can retrieve supported:

• Stored DTCs
• Pending DTCs
• Check Engine Light faults
• Freeze-frame information
• I/M readiness status
• Live sensor data
• Vehicle information

Typical engine codes may include:

• P0171 — System Too Lean
• P0300 — Random/Multiple Cylinder Misfire
• P0301–P0308 — Cylinder-specific misfires
• P0420 — Catalyst Efficiency Below Threshold
• P0440-series — EVAP faults
• P0507 — Idle Speed Higher Than Expected
• P0700 — Transmission Control System Malfunction notification

Once you retrieve a code, continue troubleshooting with the Pro Street DTC Doctor:

Read and Clear Check Engine Codes

The OBDLink MX+ can read and clear supported OBD-II trouble codes.

That means you can retrieve a Check Engine fault, investigate the cause, perform the repair and then clear the stored DTC.

Remember:

Clearing the code does not repair the vehicle.

If the underlying problem remains, the ECU can detect the fault again.

A proper diagnostic workflow is:

1. Read the code.
2. Save the DTC.
3. Review freeze-frame data.
4. Check live data.
5. Diagnose the problem.
6. Repair the vehicle.
7. Clear the code.
8. Verify that the fault does not return.

Enhanced OEM Diagnostics

One of the MX+’s biggest advantages over generic Bluetooth adapters is:

enhanced manufacturer-specific diagnostics.

Generic OBD-II is largely focused on powertrain and emissions information.

Enhanced OEM diagnostics can expose additional manufacturer-specific:

• DTCs
• PIDs
• Module information
• Sensor data

Depending on vehicle support, that can include systems such as:

• ABS
• SRS
• Transmission
• TPMS
• Body-related modules

OBDLink includes free enhanced diagnostic add-ons with the MX+ for supported vehicles.

Current OBDLink coverage includes enhanced support for brands within groups such as:

• Ford
• Lincoln
• Mercury
• GM
• Chevrolet
• GMC
• Buick
• Cadillac
• Mazda
• Nissan
• Infiniti
• Toyota
• Lexus
• Scion
• Honda
• Acura
• Hyundai
• Kia

Exact available modules, DTCs and PIDs vary by vehicle.

Always verify exact coverage before purchasing specifically for an enhanced system.

ABS Diagnostics

On supported vehicles and applications, the MX+ can provide access to:

ABS diagnostic information.

Potential information may include:

• ABS trouble codes
• Wheel-speed data
• Brake-system parameters
• Manufacturer-specific ABS PIDs

That is significantly more useful than a basic generic OBD-II adapter.

However:

ABS access is not universal.

Vehicle and software compatibility must still be confirmed.

SRS and Airbag Diagnostics

The same applies to:

SRS / airbag systems.

Enhanced apps may allow the MX+ to retrieve manufacturer-specific airbag module DTCs on supported vehicles.

Do not assume every car exposes SRS information through every app.

Transmission Diagnostics

Enhanced OEM support can also provide access to transmission data that generic OBD-II adapters may not expose.

Depending on the vehicle and software, that can include:

• Transmission DTCs
• Fluid temperature
• Gear information
• Solenoid data
• Additional TCM parameters

This is especially useful when a generic scan only returns:

P0700.

P0700 usually indicates that the transmission controller has requested illumination of the MIL.

The actual transmission DTC may require direct TCM access.

See:

https://my.prostreetonline.com/dtc-doctor/p0700-code-transmission-control-system-malfunction/

TPMS Data

Some supported enhanced applications may also expose:

TPMS information.

That can potentially include:

• Tire-pressure values
• Module DTCs
• Sensor status

Do not confuse TPMS diagnostics with:

• Sensor programming
• Sensor cloning
• Universal TPMS relearning

Those capabilities depend on the vehicle, software and dedicated service functionality.

MS-CAN Support

The OBDLink MX+ supports:

MS-CAN.

This is an important advantage for Ford and Mazda enthusiasts.

Certain modules on Ford-family vehicles communicate through networks that basic ELM327 adapters may not access without additional hardware or a manual HS/MS-CAN switch.

The MX+ can communicate with the advanced network directly.

That makes it especially attractive for:

FORScan users.

SW-CAN Support

The MX+ also supports:

SW-CAN

for supported GM applications.

This can provide access to additional GM network information beyond standard generic OBD-II.

For owners working with:

• Chevrolet
• GMC
• Buick
• Cadillac

that makes the MX+ considerably more useful than a generic Bluetooth adapter.

OBDLink MX+ and FORScan

The MX+ is officially listed as compatible with:

FORScan Lite

for supported iOS devices.

OBDLink also supports FORScan applications across its adapter ecosystem.

FORScan is designed specifically for:

• Ford
• Lincoln
• Mercury
• Mazda

and can expose significantly more information than generic OBD-II software.

Depending on vehicle and software support, that can include:

• Manufacturer-specific DTCs
• Additional control modules
• Enhanced PIDs
• Vehicle configuration functions

Exact capabilities depend on FORScan and the vehicle.

OBDLink MX+ and BimmerCode

The MX+ is officially compatible with:

BimmerCode

on supported iOS and Android devices.

BimmerCode allows selected BMW and MINI owners to modify supported vehicle coding options.

Potential changes may include settings involving:

• Lighting
• Locks
• Displays
• Convenience functions
• Instrument behavior

The exact available coding functions depend on:

• BMW/MINI chassis
• Model year
• ECU
• BimmerCode support

Official BimmerCode compatibility:

https://bimmercode.app/cars/

Coding Is Not ECU Performance Tuning

BimmerCode-style vehicle coding should not be confused with:

ECU performance tuning.

Coding generally changes configurable vehicle behaviors.

It does not automatically mean the MX+ can:

• Flash performance maps
• Change fuel maps
• Modify boost targets
• Reprogram every ECU
• Replace professional factory programming equipment

OBDLink MX+ and Torque

The MX+ also supports:

Torque

for Android.

Torque is popular among automotive enthusiasts for:

• Live gauges
• Engine monitoring
• DTC scanning
• Performance displays
• Custom dashboards
• Data logging

This makes the MX+ useful as both a diagnostic adapter and a real-time vehicle data interface.

OBDLink MX+ and OBD Fusion

OBD Fusion is another officially supported application.

Depending on configuration, it can provide:

• Generic OBD-II diagnostics
• Live data
• Custom dashboards
• Data logging
• Enhanced manufacturer diagnostics

Some optional manufacturer-specific features may require additional app purchases.

OBDLink MX+ and AlfaOBD

The MX+ is officially supported by:

AlfaOBD

on Android.

AlfaOBD is designed for many FCA-family vehicles including applications involving:

• Alfa Romeo
• Fiat
• Chrysler
• Dodge
• Jeep
• Ram

Depending on the vehicle and software, AlfaOBD can expose significantly more manufacturer-specific functionality than a standard OBD-II app.

Again:

the app determines the available advanced functions.

OBDLink MX+ and Carista

The MX+ is compatible with:

Carista

on supported iOS and Android devices.

Depending on vehicle coverage and app subscription, Carista may provide:

• Diagnostics
• Customization
• Service functionality
• Manufacturer-specific features

Some Carista functionality requires separate payment.

OBDLink MX+ and OBD JScan

The MX+ is also compatible with:

OBD JScan.

JScan is popular among Jeep and FCA owners.

Depending on vehicle support, it can provide:

• Enhanced diagnostics
• Live data
• Configuration functions
• Manufacturer-specific information

OBDLink MX+ and DashCommand

DashCommand is officially listed as a compatible app.

It can turn an iPhone or Android device into a customizable vehicle display with:

• Live gauges
• Engine data
• Performance information
• Diagnostic functions

Included OBDLink App

Unlike adapters that require you to purchase third-party software just to get started, the MX+ includes access to the:

OBDLink app

for iOS and Android.

The app can provide:

• DTC reading
• DTC clearing
• Live dashboards
• Vehicle information
• Enhanced diagnostics
• Data logging
• Firmware updates

OBDLink also includes free enhanced OEM diagnostic add-ons with the MX+ for supported manufacturers.

Included OBDwiz Software for Windows

Windows users also receive:

OBDwiz

with the MX+.

That allows a compatible Windows computer to perform OBD-II diagnostic and monitoring functions without purchasing another basic diagnostic package.

iPhone Compatibility

The MX+ works with:

• iPhone
• iPad

and supports the OBDLink app plus numerous compatible iOS third-party applications.

That distinguishes it from many older Bluetooth OBD adapters that only support Android.

Android Compatibility

Android users gain access to one of the largest compatible app ecosystems.

Applications include:

• OBDLink
• Torque
• BimmerCode
• AlfaOBD
• Carista
• Car Scanner
• OBD Fusion
• OBD JScan

and others.

Windows Compatibility

The MX+ also works with compatible:

Windows PCs.

OBDLink includes OBDwiz software for Windows and provides firmware-update utilities.

That makes the MX+ useful in a garage environment where a laptop may be more convenient than a phone.

Secure Bluetooth Pairing

OBDLink uses a physical connection button and:

128-bit wireless encryption

to help secure the Bluetooth link.

Unlike many inexpensive adapters that continuously broadcast their presence, OBDLink specifically designed the MX+ around more controlled pairing.

Physical access to the adapter is required to enable pairing.

Bluetooth Version

One point worth correcting from generic marketplace assumptions:

The MX+ is officially specified as using:

Class 2 Bluetooth v3.0.

Do not market it as Bluetooth 5.x simply because newer adapters use newer Bluetooth revisions.

Bluetooth version alone also does not determine diagnostic performance.

The MX+ gets much of its performance from its purpose-built OBD communication hardware and software architecture.

Fast Data Transfer

OBDLink markets the MX+ as a very high-speed Bluetooth OBD-II adapter.

That can benefit applications involving:

• Multiple live PIDs
• Dashboards
• Data logging
• Performance monitoring

However, actual refresh rates still depend on:

• Vehicle protocol
• ECU
• Number of requested PIDs
• Application
• Mobile device

BatterySaver Technology

One of the MX+’s strongest practical features is:

BatterySaver Technology.

The adapter automatically enters a low-power state when appropriate.

OBDLink lists approximately:

2 mA

of current draw in low-power mode.

This makes it better suited to remaining installed than many cheap Bluetooth dongles.

Automatic Sleep and Wake

The MX+ automatically:

• Sleeps
• Wakes

without requiring a manual power switch.

That is especially useful if the scanner is being used for:

• Continuous vehicle monitoring
• Trip logging
• Dashboard apps
• Frequent diagnostics

Overvoltage Protection

OBDLink specifies:

overvoltage protection up to 100 volts.

That provides additional electrical protection for the adapter during unusual vehicle voltage events.

The normal operating range is:

8–18 volts.

Can You Leave the OBDLink MX+ Plugged In?

The MX+ is specifically engineered to remain connected more safely than generic adapters.

Its:

• Automatic sleep mode
• BatterySaver low-power mode
• Overvoltage protection

make permanent or semi-permanent installation practical for many regularly driven vehicles.

Still, if a vehicle has:

• A weak battery
• Existing parasitic drain
• Very long periods of storage

disconnecting accessory devices remains sensible.

Vehicle Compatibility

OBDLink states that the MX+ works with:

all 1996 and newer OBD-II cars and light trucks sold in the United States.

It also supports:

• EOBD
• JOBD
• International OBD-II variants

Generic OBD-II compatibility is different from enhanced OEM feature compatibility.

The vehicle may support standard engine diagnostics without supporting every enhanced module or function.

Hybrid and EV Compatibility

Do not automatically assume full hybrid or EV diagnostic support.

OBDLink notes that compatibility with hybrids and electric vehicles can vary.

If your primary goal involves:

• Traction battery data
• Battery state of health
• Cell voltages
• Inverter information
• EV charging data

verify the exact vehicle and app before purchasing.

Manufacturer-Specific Data

One of the biggest reasons to buy the MX+ over a cheap ELM327 adapter is access to manufacturer-specific parameters.

For example, a generic adapter might show:

• Engine RPM
• Coolant temperature
• Vehicle speed

while enhanced diagnostics may provide:

• Transmission temperature
• ABS wheel speeds
• Airbag DTCs
• Manufacturer-specific sensor values
• Network module information

The exact data available depends on the vehicle.

Live Data for Diagnostics

Live data can dramatically improve troubleshooting.

For example, when diagnosing a lean condition, you could compare:

• Short-term fuel trim
• Long-term fuel trim
• MAF data
• MAP data
• Engine RPM
• Oxygen-sensor behavior

If you retrieve:

P0171

see:

https://my.prostreetonline.com/dtc-doctor/p0171-code-system-too-lean-bank-1/

Freeze-Frame Data

Supported freeze-frame information can help identify the vehicle conditions present when a DTC was stored.

Potential values may include:

• RPM
• Vehicle speed
• Engine load
• Coolant temperature
• Fuel trim

This is often far more useful than simply reading the five-character trouble code.

Emissions Readiness

The MX+ can display:

I/M readiness monitors

through compatible software.

These can help determine whether the vehicle is ready for an emissions inspection.

For federal emissions information:

https://www.epa.gov/vehicle-and-fuel-emissions-testing

Don’t Clear Codes Right Before Smog Testing

Clearing engine DTCs can reset readiness monitors to:

Not Ready.

That can prevent the vehicle from passing an OBD-based emissions inspection even if the Check Engine Light is currently off.

Repair the fault first.

Clear the code.

Complete the necessary drive cycle.

Then check readiness again.

Free Firmware Updates

OBDLink provides firmware updates for the MX+.

Current firmware updates can be installed through:

• OBDLink app on iOS
• OBDLink app on Android
• STN Firmware Updater on Windows

Updates can provide:

• Bug fixes

The MX+ should therefore not automatically be marketed as a universal bidirectional scan tool.

Some third-party applications may perform:

• Coding
• Module configuration
• Active tests
• Service procedures

on supported vehicles.

But those functions are provided by the:

software + vehicle + adapter combination

rather than by the MX+ alone.

Does the OBDLink MX+ Perform Bidirectional Tests?

Potentially, with compatible third-party applications and supported vehicles.

But this should not be advertised as a universal MX+ feature.

For example, an application may support a particular:

• Active test

• Vehicle customization
• Service routine

while another app may not.

Always verify the exact application and vehicle.

Does It Reset Oil Service?

Not universally.

A compatible third-party application may provide service-reset capability on certain vehicles.

The MX+ itself is primarily the communication adapter.

Does It Perform ABS Bleeding?

Do not assume universal ABS bleed capability.

If an app provides ABS service functions for a particular vehicle, the MX+ may act as the communication interface.

That does not make ABS bleeding a guaranteed function of the adapter itself.

Does It Program Keys?

Do not market the MX+ as a universal:

• Key programmer
• Immobilizer programmer
• Locksmith tool

unless a specific supported application and vehicle combination documents the function.

Does It Program or Flash ECUs?

The MX+ should not be presented as a universal ECU programming platform.
