| 1 |
Was "Engine and Emission Control System Check" performed? |
Go to Step 2. |
Go to ENGINE AND EMISSION CONTROL SYSTEM CHECK . |
| 2 |
DTC check
- Check DTC.
Is there any CAN-DTC? |
Go to CAN DTC (LOST COMMUNICATION AND COMMUNICATION BUS OFF) TABLE
. |
Go to Step 3. |
| 3 |
Fuel level sensor signal circuit check
- Confirm that ignition mode of keyless push start system is "OFF".
- Disconnect connectors from combination meter and fuel level sensor.
- Check for proper terminal connection to combination meter connector and fuel level sensor connector.
- If connections are OK, check the following points.
- Resistance of "A1" circuit: less than 1 Ω
- Resistance between "A1" circuit and ground: infinity
- Resistance between "A1" circuit and each terminal at fuel level sensor connector: infinity
- Voltage of "A1" circuit: 0 - 1 V (with ignition mode of keyless push start system in "ON")
Are they in good condition? |
2WD model: Go to Step 5. 4WD model: Go to Step 4. |
Repair or replace defective wire harness. |
| 4 |
Sub fuel level sensor signal circuit check
- Push engine switch to change ignition mode to "OFF".
- Disconnect connector from sub fuel level sensor.
- Check for proper terminal connection to sub fuel level sensor connector.
- If connections are OK, check the following points.
- Resistance of "A2" circuit: less than 1 Ω
- Resistance between "A2" circuit and ground: infinity
- Resistance between "A2" circuit and each terminal at sub fuel level sensor connector: infinity
- Voltage of "A2" circuit: 0 - 1 V (with ignition mode of keyless push start system in ON)
Are they in good condition? |
Go to Step 5. |
Repair or replace defective wire harness. |
| 5 |
Fuel level sensor ground circuit check
- Check the following points.
- Resistance of "A3" circuit: less than 3 Ω
- Voltage of "A3" circuit and ground: 0 - 1 V (with ignition mode of keyless push start system in ON)
Are they in good condition? |
Go to Step 6. |
Repair or replace defective wire harness. |
| 6 |
Fuel level sensor check
- Check fuel level sensor, see FUEL LEVEL SENSOR INSPECTION
.
Is it in good condition? |
Replace combination meter, see COMBINATION METER REMOVAL AND INSTALLATION
.
If DTC P0461 is still detected, replace ECM. |
Repair or replace defective parts. |
