WIRING DIAGRAM
INSPECTION PROCEDURE
| 1.CHECK HEADLIGHT ASSEMBLY (LO BEAM) |
Check that the headlights illuminate in LO beam.
- OK:
- Headlights illuminate in LO beam
| 2.INSPECT HEADLIGHT CLEANER SWITCH ASSEMBLY |
Disconnect the G4 cleaner switch connector.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
| Tester Connection | Condition | Specified Condition |
| 8 (B) - 5 (L) | Headlight cleaner switch off | 10 kΩ or higher |
| 8 (B) - 5 (L) | Headlight cleaner switch on | Below 1 Ω |
| | REPLACE HEADLIGHT CLEANER SWITCH ASSEMBLY ()
|
|
|
| 3.CHECK HARNESS AND CONNECTOR (HEADLIGHT CLEANER SWITCH ASSEMBLY - HEADLIGHT CLEANER CONTROL RELAY AND MAIN BODY ECU) |
Disconnect the headlight cleaner control relay connector.
Disconnect the G4 switch connector.
Disconnect the 2D main body ECU connector.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
| Tester Connection | Condition | Specified Condition |
| 2 (H) - G4-8 (B) | Always | Below 1 Ω |
| G4-5 (L) - 2D-23 (HRLY) |
| 2 (H) - Body ground | Always | 10 kΩ or higher |
| G4-8 (B) - Body ground |
| G4-5 (L) - Body ground |
| 2D-23 (HRLY) - Body ground |
| | REPAIR OR REPLACE HARNESS OR CONNECTOR |
|
|
| OK | |
| |
| REPLACE HEADLIGHT CLEANER CONTROL RELAY ()
