Test D: The Message Center Switch Does Not Operate Correctly (High Series Instrument Cluster [IC])

PINPOINT TEST D: THE MESSAGE CENTER SWITCH DOES NOT OPERATE CORRECTLY (HIGH SERIES INSTRUMENT CLUSTER [IC])

Normal Operation
The message center switch uses circuit CMC29 (GN/VT) to communicate the requested switch function to the instrument cluster (IC) message center. The message center switch is grounded through circuit RMC32 (GN/BU). Each message center switch uses a different resistance value allowing the instrument cluster (IC) to determine which switch is pressed.

This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Message center switch
- Instrument cluster (IC)
