Faulty Wiring or Connectors

Faulty wiring or connectors can also be the cause of the U0131:87 code. Because the PSCM and GWM communicate through the wiring, any problems with the wiring can prevent the two from communicating correctly. If this is the case, it is essential to replace any faulty wiring or connectors to ensure that the two are able to communicate appropriately.

Defective GWM

The GWM, or Generic Wiring Module, is responsible for controlling the communication between the PSCM and the vehicle’s other systems. When the GWM is defective, it can cause the U0131:87 code to appear. In this case, it is essential to replace the GWM in order to resolve the issue.
