DIAGNOSTIC TEST
1. POWERTRAIN CONTROL MODULE
Turn the ignition on.
With the DRBIII(R), read DTCs.
Q: Does the DRBIII(R) display any PCM DTCs?
YES: Refer to the DRIVEABILITY category and perform the appropriate symptom. Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
NO: Go To 2
2. INSTRUMENT CLUSTER
Turn the ignition off.
Perform the Instrument Cluster Self Test.
NOTE: The Self Test can be initiated manually by depressing and holding the Trip Reset button while turning the ignition on, or by using the DRBIII(R).
Observe the gauge in question while the Instrument Cluster performs the Self Test.
The gauges should position at the following calibrations points:
Speedometer MPH: 0, 20, 60, 90
Tachometer Gas: 0, 1000, 3000, 6000
Fuel: E, 1/4, 1/2, 3/4, F
Coolant: Cold, 1/4, 1/2, 3/4, HI
Volts: 6, 9, 12, 15, 17
Q: Did the gauge in question operate properly?
YES: The condition is not present at this time. Monitor DRBIII(R) parameters while wiggling the related wire harness. Refer to any Technical Service Bulletins (TSB) that may apply. Visually inspect the related wiring harness and connector terminals. Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
NO: Replace and configure the Instrument Cluster. Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
