The automobile fault code P1687 indicates a problem with the instrument cluster.

The most common symptom is the engine light being ON or the service engine soon warning light. The cause could be a faulty instrument cluster, an open or shorted instrument cluster harness, a poor electrical connection in the instrument cluster circuit, or a faulty powertrain control module (PCM). To fix this issue, you should visually inspect the wiring harness and connectors, checking for any damage or broken, bent, pushed out, or corroded pins in the connectors.

The repair time for this problem is estimated to be around 1.0. To interpret the fault code, you can refer to the possible causes listed above and perform the necessary inspections and repairs.

The automobile fault code P1687 can be diagnosed and fixed within an estimated repair time of 1.0 hour.

The cost of the repair will depend on the hourly rate charged by the auto repair shop, which typically ranges between $75 and $150 per hour.

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.

What are the possible causes of the automobile fault code P1687?

If you see the engine light or service engine soon warning light on, the fault code P1687 could be the culprit. This code is often caused by a faulty instrument cluster, an open or shorted instrument cluster harness, a poor electrical connection in the instrument cluster circuit, or a faulty powertrain control module (PCM). To fix this issue, visually inspect the wiring harness and connectors, checking for any damage or broken, bent, pushed out, or corroded pins in the connectors. Don’t forget to also check the possible causes listed above.

How can I visually inspect the wiring harness and connectors to fix the P1687 fault code?

If you’re dealing with the P1687 fault code and notice that your engine light is on, it’s time to take action. The possible causes could be a faulty instrument cluster, an open or shorted instrument cluster harness, a poor electrical connection in the instrument cluster circuit, or a faulty powertrain control module (PCM). To fix this issue, visually inspect the wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded pins in the connectors. Don’t delay, get to the bottom of this problem and ensure your vehicle is running smoothly.

What should I look for when checking for damaged components and connector pins to resolve the P1687 fault code?

To resolve the P1687 fault code, start by visually inspecting the wiring harness and connectors. Look for any signs of damage and check for broken, bent, pushed out, or corroded connector pins. These issues can cause a poor electrical connection or an open or shorted circuit in the instrument cluster. Additionally, check for a faulty instrument cluster or powertrain control module (PCM). By addressing these possible causes, you can fix the issue and turn off the engine light or service engine soon warning light.
