DESCRIPTION
Automatic headlight beam level control system data and Diagnostic Trouble Codes (DTCs) can be read from the Data Link Connector 3 (DLC3) of the vehicle. When the system seems to be malfunctioning, use the GTS to check for malfunctions and perform repairs.
CHECK DLC3
Check the DLC3.
INSPECT BATTERY VOLTAGE
Measure the battery voltage.
If the voltage is below 11 V, recharge or replace the battery.
DIAGNOSIS SYSTEM
| *a | Headlight Leveling Warning Light |
| *b | Multi-information Display (for Standard) (for Sport Package, Movable meter ring activated) |
| *c | Multi-information Display (for Sport Package, Movable meter ring not activated) |
If the automatic headlight beam level control system malfunctions, the headlight leveling warning light illuminates and "Check Headlight System" is displayed on the multi-information display.
Tech Tips
In this case, the headlight light control ECU sub-assembly LH stores DTCs.
When the system returns to normal, the headlight leveling warning light turns off and "Check Headlight System" is no longer displayed on the multi-information display.
