<<See All OBD Codes

Do you know what P0600 error code is? If you don’t know, then it might be difficult to diagnose this error. This is a common type of error code which indicates that the communication link of ECU has failed. You can see this code, along with other trouble codes in addition to the codes of traction control system and ABS.

There are many functions that a PCM performs in a modern vehicle like managing the Fuel system, Ignition system, Transmission, Anti-Lock Brake and Traction Control systems. The control modules can talk to each other with the help of serial communication link. If there is a P0600 error code in PCM it means the communication is lost with 1 or other control modules of PCM.

What causes this problem with the Serial Communication Link Malfunction?

• Defective ECU of the ECU has already failed.
• The battery voltage is very low.
• The wiring harness of the ECU is open, it is either short or the electrical connection is very poor.

1. ECU - The Engine control unit has to function normally. If it has already failed or if the ECU is damaged or broken it will give rise to this error code.
2. Powertrain Control module - A defective powertrain control module is the one common reasons in most of the OBD error code. Replace the defective PCM and if you are looking for the right replacement part, you can grab them easily at Parts Avatar.
3. Wheel sensor - The wheel sensor is generally used for reading the wheel rotation. If the sensor is damaged or faulty replace them immediately. Also, you can grab them at best prices online from Parts Avatar.
