4) Check the main relay
5) Check that the Brown-Black cable of the main relay is earthed.
6) With the key switch set to «ON», check if there is voltage between the Orange cable of the main
relay and the ground connection.
7) If there is no voltage, check the continuity of the cable harness with the fuse box (fuse No. 1).
8) Check the working order of fuse No. 7.
9) Check the continuity of the cable harness between the main relay, fuse box (fuse No. 7) and the low-
beam light relay (Red-Green cables).
10) Check the low-beam light relay.
11) Check the continuity of the cable harness between the low-beam light relay and the bulb (Brown-
White cable).
12) Check the continuity of the cable harness between the low-beam light relay and the control unit
vehicle-side connector (Yellow-Grey cable).
13) Check that the Black cable of the bulb is earthed.
HIGH-BEAM LIGHT CHECK
1) Check the bulb and, if necessary, replace it as indicated in the bulb table.
2) Check the continuity of the cable harness between the light switch and the low-beam light relay
(Brown-White cable).
3) Check the light switch contacts.
4) Check the continuity of the cable harness between the light switch and the high-beam light relay
(Purple cable).
5) Check the high-beam light relay.
6) Check the continuity of the cable harness between the high-beam light relay and fuse No. 7 (Red-
Green cable).
7) Check that the Black cable of the high-beam light relay is earthed.
8) Check the continuity of the cable harness between the high-beam light relay and the bulb (Purple-
White cable).
9) Check that the Black cable of the bulb is earthed.
10) If the high-beam light does not work in flashing mode:
- Check the continuity of the cable harness of the main relay and fuse No. 8 (Orange cable).
- Check fuse No. 8.
- Check the continuity of the cable harness between the fuse box (fuse No. 8) and the light switch
(Purple-White cable).
- Check the high-beam flash switch contacts.
- Check the continuity of the cable harness between the high-beam flash switch and the high-beam light
relay (Purple cable).
STOP LIGHT CHECK
1) Check LEDs and replace the rear light assembly if necessary.
