Powertrain Verification Test VER-4

NOTE: After completing the Powertrain Verification Test the TRANSMISSION VERIFICATION TEST  must be performed. See PROGRAMMING .
NOTE: If the PCM has been replaced and the vehicle is equipped with a 2.4L Turbo, manual transmission, the pinion factor must be programmed into the PCM. Failure to do so will cause the speedometer to become inoperative or inaccurate.
NOTE: If the PCM has been replaced and the correct VIN and mileage have not been programmed, a DTC will be set in the ABS Module, AIRBAG Module and the SKIM. See PROGRAMMING .
NOTE: If the vehicle is equipped with a Sentry Key Immobilizer System, Secret Key data must be updated. See PROGRAMMING  for the PCM, SKIM and the Transponder (ignition key) for programming information.
