What is the P0600 fault number? What is Serial Communication Link Failure? How can you fix P0600 fault codes? What are the symptoms and causes for the P0600 fault code
What is the P0600 Fault code? What does it signify?
Diagnose trouble code P0600 “Serial Communication Link Problem” . It means that the powertrain control modules (PCMs) have failed internally or are unable to communicate with each other over the data network.
This code is indicative of a problem in the wiring between one of the supporting control module and the PCM. This code, P0600, is generic and applies to all computer-controlled vehicles. This code indicates that the PCM has lost control of one or more control module. Many vehicles have up to 18 supporting control modules that are controlled by the primary computer. A series of wiring harnesses called the controller area networks (Can Bus Automotive Network), allows for communication between modules. If the PCM cannot communicate with one or more module after eight consecutive start cycles, a fault code P0600 will be issued.
What causes the P0600 Fault code?
Here are some reasons why P0600 should be set.
- – Defective PCM
- – Control module circuit problems, such as loose or damaged connections or wiring.
- – Data network problems (Can Bus) harness
- – Low battery charge
- Software for controlling the out-of-date control module
What are the symptoms of P0600 Malfunction Code?
This code refers to the control mechanism of the system, rather than any component. Depending on the exact location of the loss in communication control, these symptoms could occur:
- – Warning lamps located on the instrument panel (engine and transmission fault lamps), ABS and traction control system lamp lamps, etc.
- – Engine running very hard or not at all
- – Idle fluctuations
- Engine misfire
- – Engine stalling
- – Low engine performance
- – Irregular transmission shifting
- – Increased fuel consumption
- – The vehicle may enter fail-safe mode
The PCM controls most car systems and can cause malfunctions to disable many other processes. Keep in mind that the code P0600 indicates a communication breakdown. If the communication between the PCM (the ignition control module) is broken, misfire symptoms could occur. Inexperienced mechanics may not be able to find the problem.
How to Fix the P0600 Fault Code
These repairs could resolve the P0600 fault code
- Repair or replacement of the PCM harness
- – Repair of bad electrical connections
- Low battery voltage? Diagnose the problem and repair it
- – Reprogramming or replacing of the PCM/ECM/ECU
The PCM will stop working if it has lost its memory because it is not powered enough.
How Serious Is the P0600 Fault Coding?
Fault code 600 can lead to symptoms that may affect the vehicle’s functioning. The vehicle should be stopped from being used if severe symptoms develop. A code P0600 will disable the ABS and traction controls systems. Driving in bad weather is dangerous for your safety.
