Some customers may comment on an intermittent extended crank time in hot engine restart and the starter motor may not disengage after engine start.
Important: Before reprogramming the PCM, verify the customer concern. Refer to SI- Diagnostic System Check-Vehicle in Vehicle Control Systems. Follow the diagnostic for a possible cause of an extended crank time in hot engine restart. If no trouble is found, reprogram the PCM.
Reprogram the PCM with the latest calibrations if the above concern is encountered. An updated PCM calibration is now available to address this concern. This calibration, or any that follow, is designed to address this concern. Refer to Service Programming System (SPS) using the appropriate Service Information (SI) procedures.
