INSPECT DIFFERENTIAL OIL TEMPERATURE SENSOR
|
Yes |
Replace the differential oil temperature sensor, then go to Step 7. (See DIFFERENTIAL OIL TEMPERATURE SENSOR REMOVAL/INSTALLATION
.) |
| No |
Go to the next step. |
| 2 |
INSPECT DIFFERENTIAL OIL TEMPERATURE SENSOR SIGNAL CIRCUIT FOR OPEN CIRCUIT
- Switch the ignition off.
- Disconnect the AWD control module connector. (See AWD CONTROL MODULE REMOVAL/INSTALLATION
.)
- Disconnect the differential oil temperature sensor connector. (See COUPLING COMPONENT REMOVAL/INSTALLATION
.)
- Inspect for continuity between AWD control module terminal A (wiring harness-side) and differential oil temperature sensor terminal A (wiring harness-side).
- Is there continuity?
|
Yes |
Go to the next step. |
| No |
Refer to the wiring diagram and verify whether or not there is a common connector between AWD control module terminal A and differential oil temperature sensor terminal A.
If there is a common connector:
- Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for an open circuit.
- Repair or replace the malfunctioning part.
If there is no common connector:
- Repair or replace the wiring harness which has an open circuit.
Go to Step 7. |
| 3 |
INSPECT DIFFERENTIAL OIL TEMPERATURE SENSOR SIGNAL CIRCUIT FOR SHORT TO POWER SUPPLY
- Verify that the differential oil temperature sensor and AWD control module connectors are disconnected.
- Measure the voltage between AWD control module terminal A (wiring harness-side) and body ground.
- Is the voltage B+?
|
Yes |
Refer to the wiring diagram and verify whether or not there is a common connector between AWD control module terminal A and differential oil temperature sensor terminal A.
If there is a common connector:
- Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to power supply.
- Repair or replace the malfunctioning part.
If there is no common connector:
- Repair or replace the wiring harness which has a short to power supply.
Go to Step 7. |
| No |
Go to next step. |
| 4 |
INSPECT DIFFERENTIAL OIL TEMPERATURE SENSOR SIGNAL CIRCUIT FOR SHORT TO GROUND
- Verify that the differential oil temperature sensor and AWD control module connectors are disconnected.
- Inspect for continuity between AWD control module terminal A (wiring harness-side) and body ground.
- Is there continuity?
|
Yes |
Refer to the wiring diagram and verify whether or not there is a common connector between AWD control module terminal A and differential oil temperature sensor terminal A.
If there is a common connector:
- Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to ground.
- Repair or replace the malfunctioning part.
If there is no common connector:
- Repair or replace the wiring harness which has a short to ground.
Go to Step 7. |
| No |
Go to the next step. |
| 5 |
INSPECT DIFFERENTIAL OIL TEMPERATURE SENSOR GROUND CIRCUIT FOR OPEN CIRCUIT
- Verify that the differential oil temperature sensor and AWD control module connectors are disconnected.
- Inspect for continuity between AWD control module terminal C (wiring harness-side) and differential oil temperature sensor terminal B (wiring harness-side).
- Is there continuity?
|
Yes |
Go to the next step. |
| No |
Refer to the wiring diagram and verify whether or not there is a common connector between AWD control module terminal C and differential oil temperature sensor terminal B.
If there is a common connector:
- Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for an open circuit.
- Repair or replace the malfunctioning part.
If there is no common connector:
- Repair or replace the wiring harness which has an open circuit.
Go to Step 7. |
| 6 |
INSPECT DIFFERENTIAL OIL TEMPERATURE SENSOR GROUND CIRCUIT FOR SHORT TO POWER SUPPLY
- Verify that the differential oil temperature sensor and AWD control module connectors are disconnected.
- Measure the voltage between AWD control module terminal C (wiring harness-side) and body ground.
- Is the voltage B+?
|
Yes |
Refer to the wiring diagram and verify whether or not there is a common connector between AWD control module terminal C and differential oil temperature sensor terminal B.
If there is a common connector:
- Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to power supply.
- Repair or replace the malfunctioning part.
If there is no common connector:
- Repair or replace the wiring harness which has a short to power supply.
