Guide To P0885 OBD Error Code Solutions

<<See All OBD Codes

The trouble code P0885 can be explicated as TCM Power Relay Control Circuit/Open. This code is a generic trouble code, meaning it applies to all vehicles equipped with the OBD-II system, especially those made from 1996 up to present. It’s also more common among Audi, Citroen, Chevrolet, Ford, Hyundai, Nissan, Peugeot, and Volkswagen vehicles. Specifications on the definition, troubleshooting, and repairs, of course, vary from one make and model, powertrain configuration type, to another.

Do you want to gain some more knowledge about the P0885 trouble code? The P0885 error code would indicate that the automobile’s powertrain control module has failed to receive data from the traction control module communication circuit. This system would allow the vehicle to easily calculate the engine's RPM and optimize the fuel delivery. If there is some issue with the automobile’s traction control module communication circuit, then the P0885 fault code would start flashing up.

What causes this problem with the TCM Power Relay Control Circuit/Open?

• There can be inoperative TCM power relay
• The fuse might be burned or corroded
• Imperfect fusible link
• Some issues related to the shorted or open TCM power relay circuit
• Quirks in the TCM/PCM

Have a look at the steps which you should follow in order to diagnose this fault code:

First of all, you should research the Technical Service Bulletins (TSBs) for the specific vehicle by year, model and transmission before you start with the troubleshooting process for any malfunction. CAN is known as “controller area network.” A communication bus is represented by CAN which would allow a lot of microcontrollers to communicate with one another without the requirement for a host computer. It is a message-based agreement originally designed for vehicle utilization.

It is a compound conglomeration of wiring harnesses and connectors used as a pipeline of information shared between two or more vehicle control modules. Virtually every electrical function is controlled by these controllers of the vehicle, and the powertrain control module is the chief controller. Input data from a number of sensors is received by the control modules and emit output signals to system constituents and other control modules. We can understand this better with the help of an example. An input signal is received by the PCM from the vehicle speed sensor.

This signal is orderly moved forward to the affected control modules that utilize the data to accomplish a lot of other tasks. The code should then be cleared up and the vehicle should be operated to check if it is returning back again or not. This would prove to be very helpful to decide whether or not the failure is intermittent. Then the vehicle should be taken out for a test drive to check if the code is returning back again or not. If the code does not return back immediately, then it would mean that there is an intermittent situation.

Common Mistakes When Diagnosing the P0885 Code

• Failure in the transmission control module relay
• Transmission control module might start failing
• Problems related to the car wiring
