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 DTCs to set that may have been erased due to a dead battery.
Try to communicate with PCM if not able to communicate check fuses.
Ensure the Powers and Ground to the PCM are ok.
Make sure the PCM communicates with the DRBIII and that there are no DTCs
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 DTCs with the DRBIII . If any DTCs 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 Bus is functional. Attempt to communicate with the Instrument
Cluster and VTSS, If you are unable to establish communications refer to the
Communication category for the proper symptoms.

communication with the DRBIII and check for DTCs that may be stored in the
Sentry Key Immobilizer Module (SKIM). Repair the DTC(s) before continuing.
