- Perform INSTRUMENT CLUSTER DIAGNOSTIC SYSTEM CHECK under SYSTEM TESTS. Go to next step.
- Disconnect Multifunction Alarm Module (MAM) connectors. Place ignition key in ignition switch. Connect a test light between MAM connector C2 terminal "D" (Orange wire) and MAM connector C1 terminal "E" (Light Green wire). See WIRING DIAGRAMS . See Figure . If test light illuminates, go to step 12 . If test light does not illuminate, go to next step.
- Connect test light between ground and MAM connector C2 terminal "D" (Orange wire). If test light illuminates, go step 5 . If test light does not illuminate, go to next step.
- Repair open in Orange wire between fuse block and MAM connector C2 terminal "D". After repairs, go to INSTRUMENT CLUSTER DIAGNOSTIC SYSTEM CHECK under SYSTEM TESTS.
- Disconnect ignition key connector C2. Remove ignition key from ignition switch. Using DVOM, check voltage between ground and MAM connector C1 terminal "E" (Light Green wire). If no voltage is present, go to step 7 . If any voltage is present, go to next step.
- Repair short to battery voltage in Light Green wire between MAM connector C1 terminal "E" and ignition switch connector C2 terminal "F". After repairs, go to INSTRUMENT CLUSTER DIAGNOSTIC SYSTEM CHECK under SYSTEM TESTS.
- Using DVOM, check resistance in Light Green wire between MAM connector C1 terminal "E" and ignition switch connector C2 terminal "F". If resistance is 0-2 ohms, go to step 9 . If resistance is not 0-2 ohms, go to next step.
- Repair open Light Green wire between MAM connector C1 terminal "E" and ignition switch connector C2 terminal "F". After repairs, go to INSTRUMENT CLUSTER DIAGNOSTIC SYSTEM CHECK under SYSTEM TESTS.
