Low-beam failure - incorrectly shown message

VEHICLES CONCERNED

Saab 9-3 MY03-MY08 with Halogen headlights.

BACKGROUND

The Information Display in the car can in some cases erroneously show a "low beam bulb failure" message. In most cases the reason is of course that the bulb has failed, but in a minority of the cases the message is shown erroneously due to a software bug in the Underhood Electrical Center (UEC). Saab will introduce a updated software for the UEC later in 2007. It will then be possible to update the UEC via TECH2.

SYMPTOM DESCRIPTION

Information Display shows the message Low Beam, open load. Also DTC B2575 or B2699 is stored as history in the UEC. Troubleshooting via WIS has not solved the problem.

ACTION

Note

Be aware that it does not help to change the UEC or the bulb.


Recommendation is to inform the customer about the behavior and the future software update.
