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).

Carry out any pinpoint tests associated with this 
DTC using the manufacturer approved diagnostic 
system. Refer to the electrical circuit diagrams 
and check CJB power and ground supply circuits 
for short, open circuit and instrument cluster 
power and ground supply circuits for short, open 
circuit. Check CAN communications between CJB 
and instrument cluster. Check for invalid vehicle 
speed signal from ABS/instrument cluster 
gateway. Check for invalid engine speed signal 
from ECM/instrument cluster gateway. Check for 
invalid signal from CJB B100C-87

If the customer has not reported a non start 
issue, clear the DTC and check vehicle starts 
correctly. If a non start issue has been reported 
run the manufacturers approved diagnostic

follow the actions required for this DTC. Carry 
out any pinpoint tests associated with this DTC 
using the manufacturer approved diagnostic 
system. Check CAN communication between

fault with the road wheel against a curb. If the  
column lock is failing to disengage, the customer 
may be able to rectify this by rotating the 
steering wheel while pressing the engine start 
button 
If fault persists, complete a CAN network 
integrity test using the manufacturers approved 
diagnostic system. Alternatively, refer to the 
electrical circuit diagrams and check CAN circuits 
between the central junction box, the instrument 
cluster and the electronic steering column lock. 
Refer to the electrical circuit diagrams and check 
the central junction box, the instrument cluster 
and the electronic steering column lock power 
and ground supply circuits for short circuit to 
ground, short circuit to power, open circuit, high 
resistance. Repair circuit(s) as required. Clear 
DTC, perform an on demand self-test and retest 
If fault persists, check that the vehicle battery 
supply voltage is between 9-16 volts. Rectify as 
required B100D-96

Ensure the column lock bolt movement is not 
obstructed or restricted (the parked position of 
the road wheels may be exerting a turning force 
through the steering column, preventing the lock 
from releasing. The steering wheel may need to 
be held against the force to allow the column 
lock to release). Clear DTC, repeatedly lock and 
unlock car using the key fob and retest 
If fault persists, complete a CAN network 
integrity test using the manufacturers approved 
diagnostic system. Alternatively, refer to the 
electrical circuit diagrams and check CAN circuits 
between the central junction box, the instrument 
cluster and the electronic steering column lock. 
Refer to the electrical circuit diagrams and check 
the central junction box, the instrument cluster 
and the electronic steering column lock power 
and ground supply circuits for short circuit to 
ground, short circuit to power, open circuit, high 
resistance. Repair circuit(s) as required. Clear 
DTC, perform an on demand self-test and retest 
If fault persists, check and install a new electric 
steering column lock control module as required B1024-87
