Range Rover Evoque: Headlamp Leveling Control Module (HLCM)
Headlamp Control Module (HCM)
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 the control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the Warranty Policy and Procedures manual (section B1.2), 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 diagnostic trouble codes 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
Where an 'on demand self-test' is referred to, this can be accessed via the 'DTC Monitor' tab on the manufacturers approved diagnostic system
The table below lists all diagnostic trouble codes (DTCs) that could be logged in the headlamp control module, for additional diagnosis and testing information refer to the relevant diagnosis and testing section.
For additional information, refer to: Headlamps (417-01 Exterior Lighting, Diagnosis and Testing) / Headlamp Leveling (417-01 Exterior Lighting, Diagnosis and Testing).
