Repair Instructions

Step 1: Clear Fault Codes

  1. Connect the OBD-II scanner to the vehicle's diagnostic port.
  2. Read and document any fault codes related to the adaptive headlights.
  3. Clear the codes and turn the vehicle on to see if the issue persists.

Step 2: Check and Replace Bulbs (if necessary)

  1. Open the hood and access the headlight assembly.
  2. Remove the headlight cover to gain access to the bulbs.
  3. Inspect the bulbs for any signs of damage or failure. Replace any faulty bulbs.

Step 3: Inspect Headlight Alignment

  1. Using a headlight alignment tool, check the alignment of both headlights.
  2. Adjust the aim of the headlights according to the specifications in the repair manual.

  2. Follow the instructions in the repair manual to perform the calibration procedure.

Step 6: Headlight Control Module Testing

  1. If issues persist, the Headlight Control Module may be faulty.
  2. Test the HCM by checking for power and ground at the module.
