Shift Indicator: Testing and Inspection
If the UPSHIFT lamp does not operate properly:
Use the TECH-1 to monitor PCM to IPC Normal Mode Communication. If the UPSHIFT Telltale reading corresponds with the malfunctioning lamp,
refer to Computers and Controls / System Diagnosis to diagnose the PCM. If the UPSHIFT Telltale reading is not the same as the lamp, then replace the
Instrument Panel Cluster (IPC).
