PINPOINT TEST A: THE MESSAGE CENTER IS NOT OPERATING CORRECTLY

A1-A2:

Normal Operation
The message center functionality is controlled through the message center switch. The RESET and SETUP buttons are hardwired to the instrument cluster through circuit 143 (LB/YE). The INFO and SELECT buttons are hardwired to the instrument cluster through circuit 152 (LB/WH). The message center switch return is routed back to the instrument cluster through circuit 1411 (GY/OG). Each message center switch uses a different resistance value allowing the instrument cluster to determine which switch is pressed.

Possible Causes
- Instrument cluster
