DESCRIPTION
Lighting 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 AUXILIARY BATTERY VOLTAGE
Measure the auxiliary battery voltage with the power switch off.
If the voltage is below 11 V, recharge or replace the auxiliary battery.
DIAGNOSIS SYSTEM
| *a | Multi-information Display (for Optitron Meter Type) (for Sport Package, Movable meter ring activated) |
| *b | Multi-information Display (for TFT Meter Type, Movable meter ring not activated) |
If a lighting system malfunctions, "Check Headlight System" is displayed on the multi-information display.
Tech Tips
In this case, the main body ECU (multiplex network body ECU) stores DTCs.
When the system returns to normal, "Check Headlight System" is no longer displayed on the multi-information display.
