SITUATION
The customer may report that the Active Steering warning lamp had illuminated immediately after starting the engine. However, after cycling the ignition, the active steering operates normally with no warning indicator.

CAUSE
A momentary voltage drop during engine start can cause fault code 6149 "Combined position, speed monitoring" to be stored in the Active Steering Control Module. If this fault was stored the result would be the illumination of the warning lamp for the Active Steering.

PROCEDURE
If other control modules have power supply faults, perform all recommended Test Plans. When diagnosing the Active Steering (AL), perform the Test Plan for fault code 6149 first as this may be the root cause of other voltage related fault codes.
