CAUSE

Error in the Headunit-Basic (HU-B), also called Radio Professional or ENTRY head unit.
CORRECTION

1. Perform a vehicle test using the latest ISTA (Integrated Service Technical Application) 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-B, reprogram the vehicle using ISTA/P 2.49.2 or later.
Otherwise, complete all test modules relevant to head unit faults.
New integration level: F020-13-03-503 or higher
Note that ISTA/P will automatically reprogram and code all programmable control modules that do not have the
latest software.
For information on programming and coding with ISTA/P, refer to CenterNet / Aftersales Portal / Service /
Workshop Technology / Vehicle Programming.
