Perform DTC TEST Before Proceeding
Important Note:
If the Powertrain Control Module has been changed and the correct VIN and mileage have not been
programmed, a DTC will be set in the ABS, Airbag and SKIM. In addition, if the vehicle is equipped
with a Sentry Key Immobilizer Module (SKIM), Secret Key data must be updated to enable starting.
Refer to GENERAL INFORMATION SECTION 8.0 for programming the Powertrain Control Module
and the SKIM.
NOTE: If the engine will not crank or cranks but will not run, be sure to check the SKIM for
proper communication and trouble codes.
NOTE: If there are any trouble codes present they must be repaired before continuing with
the No Start Symptom diagnostics.
NOTE: The battery must be fully charged before performing any test in this manual. If the
battery is low, charge the battery and then attempt to start vehicle by cranking the engine for
15 seconds 3 consecutive times. This will allow any Trouble Codes to set that may have been
erased due to a dead battery. Read trouble codes with the DRB. If any trouble codes are
present, they must be repaired before continuing with the No Start diagnostics.
Below you will find a list of recommended procedures to correct a no start problem. Start with Test
NS-1A and it will guide you through the No Start Procedures. If you have a symptom and would like
to perform only the test that correlates to that symptom, refer to the list below for the appropriate test
procedures.
