Normal Operation
The message center switch is hardwired to the instrument cluster through circuits CMC29 (GN/VT) and RMC27 (WH/BN). To communicate the
requested switch function, each message center switch button uses a different resistance value, allowing the instrument cluster to determine which
switch is pressed.
Possible Causes
-
circuit CMC29 (GN/VT) open, short to ground, or short to voltage
-
circuit RMC27 (WH/BN) open, short to ground, or short to voltage
-
message center switch
