Automatic Vertical Headlight Aim Control System, On-Board Diagnostic (OBD)

Diagnostic Trouble Code (DTC) Table

NOTE:
- All possible malfunctions recognized by the automatic vertical headlight aim control system and printed out by the VAG1551 Scan Tool (ST) are listed according to the 5-digit DTC.
- The 5-digit DTC numbers are only shown on the printout.
- Before replacing a component suspected of malfunctioning, check all related wiring connections, harness connections and Ground (GND) connections according to the appropriate wiring diagram.
- After completing necessary repairs, connect the VAG1551 scan tool, check DTC memory (scan tool function 02) and, if necessary, erase DTC memory (scan tool function 05).
- DTC memory contains all static and sporadic faults. A malfunction is recognized as static if it exists for at least 2 seconds. If a static malfunction is no longer present after 2 seconds it will be classified as a sporadic malfunction and identified by the letters "/SP" in the lower right of the VAG1551 scan tool display.
- When the ignition is switched on, all malfunctions present are identified as "sporadic" and are only stored as static malfunctions if they are detected in the next check routine.
- A sporadic malfunction will be erased if it no longer exists after 50 driving cycles (ignition on for at least 5 minutes, road speed above 30 km/h or 18 mph).
