REPAIR PROCEDURE:
NOTE: This is a coordinated update that requires flashing both the ABS module and
the RBC module in no particular order.
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. Reprogram the ABS and RBC modules with the latest software. Detailed instructions
for flashing control modules using the wiTECH Diagnostic Application are available by
selecting the application’s “HELP” tab.
2. 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.

second key cycle (off to on) may be required to mature an active DTCM (Drive
Train Control Module) DTC to stored allowing DTC to be cleared.
