TEST
1 Note: The following list of items must be checked before continuing with
any no start tests.
The battery must be fully charged and in good condition. A low charged battery may
produce invalid test results. If the battery is low, charge the battery and then attempt
to start the vehicle by cranking the engine for 15 seconds, 3 consecutive times.
This will allow any DTC's to set that may have been erased due to a dead battery.
Ensure the Powers and Ground to the PCM are ok.
Make sure the PCM communicates with the DRB and that there are no DTC's stored
in the PCM memory. If the PCM reports a No Response condition, refer to the
Communication category for the proper tests.
Read the PCM DTC's with the DRB. If any DTC's are present, they must be repaired
before continuing with any other No Start diagnostic tests. Refer to the Symptom list
for the related P-code that is reported by the PCM.
Ensure that the PCI bus is functional. Attempt to communicate with the Instrument
Cluster and SKIM, If you are unable to establish communicate refer to the
Communication category for the proper symptoms.
The Sentry Key Immoblilizer System must be operating properly. Check for proper
communication with the DRB and check for DTC's that may be stored in the Sentry
Key Immobilizer Module (SKIM). repair the DTC(s) before continuing.
If no DTC's are found, using the DRB select Clear PCM (Batt Disconnect).
Crank the engine several times. Using the DRB, read DTC's. If a DTC is present
perform the DTC diagnostics before continuing.
