Condition
Some customers may comment on the following conditions:
- Intermittent extended crank or hard start when the engine is still at operating temperature (hot soak). Engine cranks for approximately three seconds, starts, may misfire after starting, then clears and operates normally for the duration of the drive cycle.
- The engine cranks but will not start.
- The technician may determine that the scan tool fails to initialize with the PCM and diagnosis reveals no injector pulse or spark during cranking.
Cause
These conditions may be caused by the following:
- The PCM calibration may not be maximized for hot restart.
- The PCM may have experienced an internal fault.
Correction
- Review SI for the symptoms and conditions described above. Refer to Diagnostic Trouble Code (DTC) List - Vehicle.
• If SI does not isolate a fault, reprogram the PCM with the latest calibration available.
- Use a multiple diagnostic interface (MDI) for reprogramming and ensure that it is updated with the latest software version.
- During programming, the battery voltage must be maintained within the proper range of 12-15 volts. Only use the approved Midtronics(R) PSC 550 Battery Maintainer (SPS Programming Support Tool EL-49642) or equivalent during programming.
