CORRECTION
1. Perform a vehicle test using the latest ISTA diagnostic software.
Note:
When the ISTA system message displays: Battery voltage only "XX.XX" V. Please connect charger. Please note the displayed battery
voltage reading in the repair order comments section. This documentation is not necessary when part of an approved Technical Service repair
procedure; the battery charger is required to be attached before performing the Vehicle Test.
2. When fault code B7F8C3 is stored in the HU-H, replace the head unit. Otherwise, complete all test modules relevant to head unit faults.
3. Only after parts replacement, reprogram the vehicle using ISTA/P 2.49.2 or later.
