P1686 Fault Code: Unstable Cluster Communication – Causes And Solutions
The P1686 fault code indicates that the Powertrain Control Module (PCM) is not receiving any messages from the Smart Key Immobilizer Module (SKIM).
This code is set when the PCM detects a lack of communication between the two modules.
The Smart Key Immobilizer Module is responsible for the security of the vehicle and communicates with the PCM to ensure that the correct key is being used to start the engine.
When the PCM does not receive any messages from the SKIM, it sets the P1686 code to indicate a communication problem. If you encounter this fault code, it is important to check the wiring and connections between the PCM and the SKIM. A loose or damaged connection could be causing the lack of communication.
Additionally, it is recommended to check the SKIM module itself for any faults or malfunctions. Addressing the P1686 fault code promptly is crucial to ensure the proper functioning of the vehicle’s security system. It is recommended to consult a qualified technician or mechanic to diagnose and resolve the issue to prevent any potential security or starting problems.
