Diagnostic Aids

For diagnosis of the Instrument Panel, perform the System Check in the Instrument Panel Cluster.

Check for the following conditions:

^ Poor connection at PCM or Coolant Level Indicator. Inspect harness connectors for backed out terminals, improper mating, broken locks, improperly formed or damaged terminals, and poor terminal to wire connection.

^ Damaged harness. Inspect the wiring harness for damage. If the harness appears to be OK, disconnect the PCM and turn the ignition ON. Observe a voltmeter connected to the affected PCM circuit while moving connectors and wiring harnesses related to the PCM circuit. A change in voltage will indicate the location of the fault.

Test Description

The numbers below refer to the step numbers on the Diagnostic Table.

10. Refer to IPC Microprocessor for further diagnostics. This diagnostic only covers inputs to the PCM.

11. This vehicle is equipped with a PCM which utilizes an Electrically Erasable Programmable Read Only Memory (EEPROM). When the PCM is being replaced, the new PCM must be programmed. Refer to PCM Replacement/Programming.
