P0860 OBD Error Code: Problem & Solutions

<<See All OBD Codes

When does the P0860 error code appear in the vehicle? Are there any symptoms to identify this? This is a generic type of error code which gets stored in the vehicle if the gear shift module communication circuit is faulty. When both the TCM and PCM forget to converse with each other, then the P0860 error code will get stored in the vehicle.

In order to meet the vehicle’s performance as specified by the driver, the transmission control module and the PCM will talk with each other on a constant basis. Needless to say, this code is applicable only to vehicles which have an electronic traction control system. To calculate the vehicle’s operation efficiently, information is sent to the ECM from the gear shift module communication circuit through the CAN of the vehicle. Different modules can converse with each other with the CAN, which is a communication bus. Also, the gear shift timing can be defined with the gear shift modules.

What causes this problem with the Gear Shift Module Communication Circuit?

• Shorted or open wires, defective connectors as well as its associated components.
• The manual lever position sensor is faulty or malfunctioning.
• The gear shift module sensor connector has an adequate level of moisture in it.

1. Powertrain Control Module - Replacing a faulty PCM can help you to get rid of the P0860 error code.
2. Gear Shift Modules - Is the gear shift module faulty or defective? Replacing them immediately can help you to avoid P0861 error code in your vehicle.
3. Engine Traction Control Systems - The engine traction control system has to be defective free so that it can function normally without any troubles.
4. Transmission Wiring Harnesses - If there are any openings or cuts in your wire, they must be replaced as soon as possible.
5. Automotive Control Modules - Are you looking to fix this faulty component? Then Parts Avatar is the right place where you can find the replacement parts at affordable cost.
6. Speed Sensor Connectors - A broken or damaged speed sensor connector needs immediate fixation so as to avoid the P0861 error code.

It is essential to know the symptoms of an issue as only then you would be able to solve the problem. So that’s why we have listed out some major symptoms of OBD Code P0860 here:

Common Symptoms

• Illumination of the check engine light or the warning light.
• Traction control malfunction light will remain illuminated or it will keep blinking.
• The fuel economy is less.
• If the road condition is slippery, the vehicle will lose its traction.
• A hard shift of the vehicle.
• If you apply any gear, the vehicle will not shift in or out.
• This error code will make the vehicle reach the limp mode.

Here are some ways with the help of which you will be able to correct the OBD Code P0860:

• You have to repair if there are any openings, defectives, eroded wires, connectors as well as its related components.
• The faulty gear shift lever needs replacement if damaged.
• The malfunctioning gear shift module has to be fixed immediately.
• You have to test drive the vehicle by clearing all error codes and check again to see if the error codes reappear.

Here are some steps which you should follow in order to diagnose this fault code:

• In order to diagnose the P0860 error code, the mechanic will use multiple ways to correct the errors in which, a few of them includes:
• As a very first step, the mechanic or the technician will use an OBD-II scanner to see if there are any trouble codes stored in the system related to P0860.
• Next, the mechanic will carefully check for any possible damages or faults in any of the electrical wires or connectors which is related to the gear shift module.
• Additionally, he will use Autohex – a specialized diagnostic tool so that it can help him in great ways to pinpoint any malfunctions or damages in the system.
• Now, he will carefully store every memory of the modules with the help of a memory saving device as the process of reprogramming takes place.
• In order to check the pin values, the mechanic will use a diagnostic controller area network (CAN) scanner so that it will help him to know as to which control modules are properly operating and in operation.
• After inspecting the pin values, the mechanic will check for continuity with battery ground in the control module ground circuits.
• If he comes across any loosely or damaged electrical connectors, he will repair them as it can increase the resistance of the circuit.

Common Mistakes When Diagnosing the P0860 Code

• The powertrain control module experiences a failure.
• Malfunctioning of the transmission control module.
• The electrical wires face problems.
