WIRING DIAGRAM
INSPECTION PROCEDURE
1.CHECK WIRE HARNESS (NO. 1 TRANSFER INDICATOR SWITCH - BODY GROUND) |
Disconnect the T4 switch connector.
Measure the resistance of the wire harness side connector.
- Standard resistance:
Tester Connection Condition Specified Condition T4-2 - Body ground Always Below 1 Ω
|
| ||||
OK | |
2.INSPECT NO. 1 TRANSFER INDICATOR SWITCH (L4 POSITION SWITCH) |
Remove the transfer indicator switch.
Measure the resistance of the switch when pushing the ball at the tip of the switch.
- Standard resistance:
Tester Connection Switch Condition Specified Condition 1 - 2 Not pushed 10 kΩ or higher 1 - 2 Pushed Below 1 Ω
|
| ||||
OK | |
3.CHECK WIRE HARNESS (NO. 1 TRANSFER INDICATOR SWITCH - ECM) |
Disconnect the T4 switch connector.
Disconnect the E9 ECM connector.
Measure the resistance of the wire harness side connectors.
- Standard resistance:
Tester Connection Condition Specified Condition E9-11 (L4) - T4-1 Always Below 1 Ω E9-11 (L4) or T4-1 - Body ground Always 10 kΩ or higher
