LIGHTING (EXT) LIGHTING SYSTEM(w/ Headlight ECU) HOW TO PROCEED WITH TROUBLESHOOTING

CAUTION / NOTICE / HINT

HINT:: ·

Use the following procedure to troubleshoot the lighting system.

·

*: Use the GTS.

PROCEDURE

1.VEHICLE BROUGHT TO WORKSHOP

Result:

Proceed to
NEXT

2.INSPECT BATTERY VOLTAGE

Measure the battery voltage.

Standard voltage:: 11 to 14 V

If the voltage is below 11 V, recharge or replace the battery before proceeding to the next step.

Check the fuses and relays.

Check the connector connections and terminals to make sure that there are no abnormalities such as loose connections, deformation, etc.

Result:

Proceed to
NEXT

3.CHECK CAN COMMUNICATION SYSTEM*

Use the GTS to check if the CAN communication system is functioning normally.
