General Information - Diagnostic Trouble Code (DTC) Index DTC: Headlamp
Control Module (HCM)
Description and Operation

Headlamp Leveling Control Module (HLCM)


CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not
guarantee confirmation of a fault, and may also cause additional faults in the vehicle being tested and/or the donor vehicle.
NOTES:


If a control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the Warranty
Policy and Procedures manual, or determine if any prior approval programme is in operation, prior to the installation of a new
module/component.


Generic scan tools may not read the codes listed, or may read only 5-digit codes. Match the 5 digits from the scan tool to
the first 5 digits of the 7-digit code listed to identify the fault (the last 2 digits give extra information read by the
manufacturer-approved diagnostic system).


When performing voltage or resistance tests, always use a digital multimeter accurate to three decimal places, and with
an up-to-date calibration certificate. When testing resistance always take the resistance of the digital multimeter leads into
account.


Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.


Inspect connectors for signs of water ingress, and pins for damage and/or corrosion.


If DTCs are recorded and, after performing the pinpoint tests, a fault is not present, an intermittent concern may be the
cause. Always check for loose connections and corroded terminals.


Check DDW for open campaigns. Refer to the corresponding bulletins and SSMs which may be valid for the specific
customer complaint and carry out the recommendations as required.

The table below lists all Diagnostic Trouble Codes (DTCs) that could be logged in the Headlamp Leveling Control Module
(HLCM). For additional diagnosis and testing information, refer to the relevant Diagnosis and Testing section in the workshop
manual.
For additional information, refer to: Headlamps (417-01 Exterior Lighting, Diagnosis and Testing).

- Component internal
failure
Wiring harness fault
Front left inner sensor -
Component internal
failure
Refer to electrical wiring diagrams and check the front
bumper harness for damage/corrosion. Check sensor
circuit for short circuit to ground, short circuit to
power, open circuit. Repair or replace any wiring
harness as required
Check the connector for integrity and damage, then
re-connect sensor to confirm connection
Using the manufacturers approved diagnostic system
clear the DTC and run the on demand self test
If the problem persists remove the suspect sensor
from the bumper. Inspect the sensor connector for
signs of water ingress/corrosion. Exchange the
suspect sensor with another sensor within the
bumper that is not reporting a fault. Clear the DTC
and run the on demand self test to confirm if the
fault code now appears for the new position of the
suspect sensor. Renew the faulty sensor B1B44-01
