P1687 Fault Code: Understanding The Mysterious Electrical System Issue
When you see the fault code P1687 on your automobile, it means that the Powertrain Control Module (PCM) has not received a specific message from the Instrument Cluster within the last 20 seconds.
This code is related to the communication between the PCM and the Instrument Cluster. The Instrument Cluster messages are constantly monitored when the ignition is on.
If the PCM does not receive the expected cluster status bus message within the specified time frame, the P1687 code will be triggered. This code indicates a lack of communication between these two important components of your vehicle.
If you encounter the P1687 fault code, it is crucial to address the issue promptly. A professional diagnostic scan tool can help identify the exact cause of the communication failure. Once the problem is identified, the necessary repairs or replacements can be made to restore proper communication between the PCM and the Instrument Cluster.
Ignoring this fault code can lead to further complications and potential malfunctions in your vehicle’s systems.
FAQ
