Customer Concern

The dealer must choose which failure code to use depending on if this is a Rapid Service Update
(RSU) or Technical Service Bulletin.
• The “RF” failure code is required for essential module flash/reprogramming and can only be used after
confirmation that the VIN is included on the RSU.
• The failure code “RF” (Required Flash) can no longer be used on Technical Service Bulletin flashes.
The “RF” failure code must be used on an RSU.
• If the customer’s concern matches the SYMPTOM/CONDITION identified in the Technical Service
Bulletin, failure code CC is to be used. When utilizing this failure code, the 3C’s must be supplied.

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.
1. Is the vehicle on the RSU VIN list?
• YES>>> Proceed to Step 2.
• NO>>> Proceed to Step 3.
2. Does the PCM have the latest software already installed?
• YES>>> This bulletin has been completed, use inspect LOP **(18-19-06-GY)** to close the active
RSU. Normal diagnosis should be performed.
• NO>>> Proceed to Step 3.
3. 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.
NOTE: If the phonic wheel replacement procedure is not done correctly, DTC P1300 - Flywheel Self
Learning, will stay active.
4. Using wiTECH 2, perform a Body Control Module (BCM) “Proxi Alignment.” The procedure is located in
BCM under misc. functions.
5. Using wiTECH 2, go into the ECM Misc. Functions tab and perform the “Phonic Wheel Replacement”
routine.
6. Fully press the accelerator pedal (bring RPM up to limitation), then release up to idle three times. If the
procedure was performed properly the MIL lamp will stop blinking.
7. 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.
