Control unit for adaptive front lighting system (AFS)
NOTE: If a control module or component is suspected and the vehicle continues to be covered by the manufacturer's warranty, refer to the warranty manual before installing a new module/component (subsection B1.2), or determine if there is any previously approved special program in operation.
NOTE: Universal Scan Tools may not read the listed codes or may only read 5-digit codes. Match the 5 digits from the scan tool with the first 5 digits of the 7-digit code listed to identify the problem (the last 2 digits give additional information read by the diagnostic system approved by the manufacturer).
NOTE: Before starting diagnostic programs using Pinpoint tests, check and correct basic problems.
NOTE: Inspect the connectors for signs of water intrusion and their pins for damage and (or) traces of corrosion.
NOTE: If DTCs are logged and there is no problem after performing Pinpoint tests, an intermittent problem may be the cause. Always check for loose connections and corroded contacts.
NOTE: Before installing/replacing the headlight assembly, perform all necessary visual and mechanical checks for proper cable and terminal placement, including: corrosion, bent or unscrewed terminals or terminals, misplaced connectors, and damage to wiring harnesses due to chafing or wrong gasket.
NOTE: If the control module has been removed or replaced, clear the DTCs, turn the ignition on/off. This operation will clear any DTCs stored during installation of the unit.
Complete list of diagnostic trouble codes (DTC), which can be registered in the vehicle, see section 100-00. For more information, refer to: Diagnostic Trouble Code Index (DTC) - Fault code Headlamp Control Module (HCM) (100-00 General information, Description and principle of operation).
