All Gauges Do Not Operate
- Turn ignition on. Using scan tool, select Mechanical Instrument Cluster (MIC) CLUSTER. If scan tool displays BUS OPERATIONAL, go to next step. If scan tool does not display BUS OPERATIONAL, go to appropriate diagnosis and repair procedure under COMMUNICATIONS .
- Turn ignition on. Using scan tool, select MIC CLUSTER. If scan tool displays NO RESPONSE, go to NO RESPONSE FROM INSTRUMENT CLUSTER under COMMUNICATIONS. If scan tool does not display NO RESPONSE, go to next step.
- Using scan tool, read MIC DTCs. If scan tool displays RAM FAULT, replace circuit board in cluster. See appropriate ANALOG INSTRUMENT PANELS article. If scan tool does not display RAM FAULT, go to next step.
- Using scan tool, read MIC CLUSTER TYPE. Verify that cluster matches cluster type (e.g. US or Metric). If scan tool indicates correct instrument cluster, go to next step. If scan tool does not indicate the correct cluster, replace circuit board in cluster. See appropriate ANALOG INSTRUMENT PANELS article.
- Select BODY COMPUTER SYSTEM TEST with scan tool. If scan tool indicates Powertrain Control Module (PCM) status as INACTIVE ON BUS, go to BATTERY POWER TO MODULE DISCONNECT; IGNITION VOLTAGE TOO LOW; NO RESPONSE FROM BCM (BAT PWR DISCON'D); BATTERY POWER TO MODULE under COMMUNICATIONS. If scan tool does not indicate PCM status as INACTIVE ON BUS, go to next step.
- Turn ignition off. Using scan tool, select BODY, ELECTRO/MECH CLUSTER. Select ACTUATION TEST. If gauges move from lower to upper limits, go to next step. If gauges do not move, replace circuit board in cluster. See appropriate ANALOG INSTRUMENT PANELS article.
- Turn ignition on. Using scan tool, select BODY, BODY CONTROL MODULE, INPUT/OUTPUT and read IGNITION SWITCH RUN/START status. If scan tool displays switch CLOSED, replace Body Control Module (BCM). See BODY CONTROL MODULE (BCM) under REMOVAL & INSTALLATION. If scan tool does not display switch CLOSED, see COMMUNICATIONS .
