ABS light indication | 4-1 |
Malfunction code | 4-1 (4) |
Description of malfunction | Harness-to-harness short-circuit in the wheel sensor (right, frontward) |
Vehicle status | Not actuated right front wheel ABS |
Possible cause |
|
ECU terminals subject to inspect | The 2nd and 3rd terminals of 18 pin connector |
Detail
- Set the starter key to the "LOCK" position and disconnection the ABS ECU 18 pin connector.
- Connect a tester to the 2nd and 3rd terminals of the 18 pin connector (vehicle harness side). Measure voltage between these two terminals when a tire makes one revolution in 5 seconds.
Standard value: 150-1,999 mV (AC voltage range)
NO
Proceed to [2] Measuring resistance between terminals.YES
Normal now. Short-lived disconnection or short-circuit is likely to have occurred in the harness between the ABS ECU and the wheel sensor (right, frontward).
Inspect the harness and connectors.
Detail
- Measure resistance between the 2nd and 3rd terminals of the 18 pin connector (vehicle harness side).
Standard value: 1.0-1.3 kΩ
NO
Proceed to [3] Measuring resistance between sensor terminals.YES
Normal now. Short-lived disconnection or short-circuit is likely to have occurred in the harness between the ABS ECU and the wheel sensor (right, frontward).
Inspect the harness and connectors.
Detail
- Disconnect the wheel sensor (right, frontward) connector and measure resistance between terminals of the sensor connector.
Standard value: 1.0-1.3 kΩ
NO
Internal disconnection or short-circuit in the wheel sensor (right, frontward)
Replace the wheel sensor.
YES
Normal now. Short-lived disconnection or short-circuit is likely to have occurred in the harness between the ABS ECU and the wheel sensor (right, frontward).
Inspect the harness and connectors.
Detail
- Confirm the DTC P0206 is inactive
- Start the engine and let it idling condition.
- Verify the DTC P0206 is inactive.
- DTC Clear
- Clear the DTC with Hino DX
- Confirm the same DTC is not reoccurred
- P0206 is reoccur: Return to first process
- Other DTC appear: Refer to concerned Trouble shooting
