Condition
^ Warning light for dynamic headlight range control is displayed in the instrument cluster.
^ DTC 00003 / 14 (Control unit faulty) is registered in the dynamic headlight range control unit, address word 55.
^ Both headlights function normally.
^ Vehicles equipped with adaptive (cornering) lighting.
Technical Background
There is a software issue in the dynamic headlight range control module.
Production Solution
New software version 0010 in the dynamic headlight range control module addresses this condition. If the headlight range control module has a
software version lower than 0010 installed, then use the SVM code listed in Service to update the module.
Some control units will already have software version 0010 installed but can still exhibit the conditions mentioned above. When this occurs, the
software will need to be reflashed using a separate SVM code. The corrupt software will be overwritten. The software version does not change after
the update.
Service
1. Follow all instructions in the attached TSB 2011732 00 Software Version Management (SVM), operating instructions.
2. Update the dynamic headlight range control unit (address word 55) using the SVM action code as listed in the table above. Do not execute
both SVM action codes.
