Repair Procedure Summary

The repair primarily involves updating the software for the Adaptive Cruise Control (ACC) module. The process is as follows:

1. Prepare the Vehicle: Connect a battery charger to the vehicle to maintain a stable 12-volt system voltage throughout the reprogramming process. This prevents power fluctuations that could interrupt the update.
2. Reprogram the ACC Module: Using the wiTECH Diagnostic Application, the technician will reprogram the ACC module with the latest available software. If any issues arise during the flashing process, a ticket should be submitted to the Helpdesk via the Help menu.
3. Clear DTCs: After the software update is complete, any Diagnostic Trouble Codes (DTCs) that may have been set in various modules due to the reprogramming process will be cleared using the wiTECH application.

Required Tools or Parts

The primary tool required for this repair is a wiTECH or Equivalent scan tool, which is necessary for both diagnosis and the software reprogramming procedure.

Important Warnings

• Battery Voltage: It is crucial to install a battery charger to maintain a 12-volt system voltage during the reprogramming process. This prevents potential issues or failures during the software update.
• Interrupted Flash: If the software flash process is interrupted or aborted for any reason, the flash procedure must be restarted from the beginning to ensure proper module programming.
