Software in the Dynamic Stability Control unit (DSC)
CORRECTION
Run diagnostics with ISTA/D and work through any corresponding test modules, then program and code the vehicle with ISTA/P 2.48.0 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.
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.
