Supersedes Technical Service Bulletin Group 94 number 11 - 43 dated April 18, 2011 for reasons listed below.





Affected Vehicles





Condition
This Update has been proactively released to prevent the following condition from occurring in the vehicle:

^ Bulb out warning appearing in the DIS.

^ Main halogen bulb on one side fails.

This Update is in effect until removed.

Vehicle must meet all of the following criteria:

^ Procedure is valid only for vehicles that show the 94F4 code in the ElsaWeb Campaign/Action Information screen on the day of repair.

^ Vehicle must be within the New Vehicle Limited Warranty.

^ Procedure must be performed within the allotted time frame stated in this bulletin.

^ Procedure must be performed on applicable vehicles in dealer inventory prior to sale.

Technical Background

The service life of bulbs decreases with rising operating voltage.

Depending on the driving style (i.e. rapid acceleration) power surges can occur, which leads to increased lamp wear.

By reducing the permissible maximum voltage to 13.5 V in adaptation channel 19 of J519 the service life of the lamp can be increased.

Production Solution

Adaptation channel 19 in J519 changed to reduce permissible maximum voltage.
