Short question: What “3F [063] ALC reports an error at LSZ” means.
Background: My driver side low beam stopped working. I discovered water damage in the headlight control unit (number 5) on the drawing of the headlight from RealOEM. RealOEM.com * BMW E53 X5 4.8is Headlight, electronic parts, Xenon light The module and the corresponding headlight connector were corroded. I replaced the module and the headlight.
LCM reports an error from AHL module (57/01 - Level control system) and does not turn on headlight unless I disable AHL option in the LCM configuration. (I use BMW scanner 1.4.0) The scanner shows AHL error “3F [063] ALC reports an error at LSZ”. I replaced the AHL module, coded it but the errors stay the same:
LCM -> 16/01 - Wire, HVAC (LRA) potentiometer, open circuit
Shadow-memory:
57/01 - Level control system
AHL -> Shadow-memory:
39/6C - Telegram Speed invalid
3A/27 - Telegram yaw rate invalid
3B/37 - Telegram steering angle invalid
3D/27 - Telegram Terminal status, timeout or invalid
3F/62 - ALC reports an error at LSZ
