Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information CEM-8F19

Condition
The central electronic module (CEM) checks the signal from the right-hand Xenon lamp.
The diagnostic trouble code (DTC) is stored if the central electronic module (CEM) registers a fault in the right-hand Xenon bulb.
The diagnostic trouble code (DTC) can be detected with the ignition on and when switching between low and high beam.
The diagnostic trouble code (DTC) can be diagnosed at ignition switch position II.

Note! Each headlamp has two motors and a solenoid. One of the motors is located at the back of the headlamp unit and controls the headlamps' beam length regulation. This motor can be replaced as a separate spare part. The other motor is installed inside the headlamp unit. It manages the active headlamps (ABL) function and can only be replaced by replacing the entire headlamp unit. The solenoid is built into the headlamp and manages the switching between full and dipped beams. It can only be replaced by replacing the entire headlamp unit.
