Changing confusing message, "S&S Not Available to Hood Open".
Improved idle stability during tip in tip out.

DIAGNOSIS

Using a Scan Tool (wiTECH 2) with the appropriate Diagnostic Procedures available in DealerCONNECT/Service Library, verify all related systems are functioning as designed. If any DTCs or symptom conditions, other than the ones listed above are present, record the issues on the repair order and repair as necessary before proceeding further with this bulletin.

If the customer describes the symptom/condition listed above or if the technician finds the DTC, perform the Repair Procedure.

REPAIR PROCEDURE

NOTE: Install a battery charger to ensure battery voltage does not drop below 13.2 volts. Do not allow the charging voltage to climb above 13.5 volts during the flash process.

NOTE: If this flash process is interrupted/aborted, the flash should be restarted.

NOTE: The Body Control module (BCM) and Transmission Control Module (TCM) must be updated to the latest available software at the conclusion of this repair procedure. Refer to all applicable published service bulletins for detailed repair procedures and labor times regarding updating the BCM and TCM software.

Reprogram the ECM with the latest software. Detailed instructions for flashing control modules using the wiTECH Diagnostic Application are available by selecting the application's "HELP" tab.
Using wiTECH, Perform the PROXI Alignment Procedure Routine. This routine is available under the 'MISC functions tab of the BCM Module.
NOTE: If the "Phonic Wheel Replacement" and "RPM Sensor and/or timing chain replacement" procedures are not done correctly, DTC P1300 - Flywheel Self Learning will stay active.
Using wiTECH 2, go into the ECM Misc. Functions tab and perform one of the following procedures:
NOTE: Perform the "Phonic Wheel Replacement" procedure first and if errors occur, than perform the "RPM Sensor and/or timing chain replacement" procedure.
- "Phonic Wheel Replacement".
- "RPM Sensor and/or timing chain replacement".
Clear all DTCs that may have been set in any module due to reprogramming. The wiTECH 2 application will automatically present all DTCs after the flash and allow them to be cleared.
Verify the BCM and TCM are programmed with the latest available software. Refer to all applicable published service bulletins for detailed repair procedures and labor times regarding updating the BCM and TCM software.
