Using a Scan Tool (wiTECH) with the appropriate Diagnostic Procedures available in TechCONNECT, verify all related systems are functioning as designed. If 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.
CAUTION! There will be a choice between two calibrations. One for three sensor configuration that utilizes an ammonia sensor and one for two sensor configuration for vehicles that have had the ammonia sensor removed.
Be sure to select the correct software based on your configuration.
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.
- Reprogram the PCM with the latest available software. Detailed instructions for flashing control modules using the wiTECH Diagnostic Application are available by selecting the application’s “HELP” tab.
- After reprogramming, turn the ignition off to power down the ECM. The key must remain off for a minimum of 75 seconds.
NOTE: If DTC U05A5 – Implausible Data Received From Ammonia Sensor or U12A4 – Lost Communication With Ammonia Sensor is set after the reprogram then the PCM has the incorrect calibration installed. Reprogram the PCM with the correct calibration.
- Clear all DTCs that may have been set in any module due to reprogramming. The wiTECH application will automatically present all DTCs after the flash and allow them to be cleared.
NOTE: If DTC U1601 is present, the ECM P/N did not update, or the engine did not start after the flash, then the flash may have been unsuccessful. Restart the flash update.
- Perform the PCM Configuration routine in wiTECH located in the PCM “Misc. Functions” menu tab.
- Verify the Dosing Control Unit (DCU) software is up to date in accordance with the service procedures and labor times outlined in all applicable published service bulletins.
Reimbursable within the provisions of the warranty.
