| Possible cause | Disconnection of harness between ECU and ABS valve, internal disconnection in valve solenoid coil |
| ECU terminals subject to inspect | The 5th and 6th terminals of 18 pin connector |
Detail
- Set the starter key to the "LOCK" position and disconnect the ABS ECU 18 pin connector and 15 pin connector.
- Measure resistance between the 6th terminal of the 18 pin connector (vehicle harness side) and the 13th terminal of the 15 pin connector (vehicle harness side).
Standard value: 10-20 Ω
NO
Proceed to [3] Measuring resistance between valve terminals.YES
Proceed to [2] Measuring resistance between terminals
- Measure resistance between the 5th terminal of the 18 pin connector (vehicle harness side) and the 13th terminal of the 15 pin connector (vehicle harness side).
Standard value: 10-20 Ω
NO
Proceed to [3] Measuring resistance between valve terminals.YES
Normal now. Short-lived disconnection is likely to have occurred in the harness between the ABS ECU and the ABS valve (right, frontward).
Inspect the harness and connectors.
- Disconnect the ABS valve (right, frontward) connector and measure resistance between the 4th and 1st terminals and between the 4th and 3rd terminals of the valve connector.
Standard value: 10-20 Ω
NO
Abnormality in ABS valve (right, frontward)YES
Abnormality in harness
- Confirm the DTC P0805 is inactive
- Start the engine and let it idling condition.
- Verify the DTC P0805 is inactive.
- DTC Clear
- Clear the DTC with Hino DX
- Confirm the same DTC is not reoccurred
- P0805 is reoccur: Return to first process
- Other DTC appear: Refer to concerned Trouble shooting
