All| ABS light indication | 3-3 |
| Malfunction code | 3-3 (3) |
| Description of malfunction |
|
| Vehicle status | Not actuated right rear wheel ABS |
| Possible cause |
|
| ECU terminals subject to inspect | The 7th and 13th terminals of 18 pin connector |
Detail
- Set the starter key to the "LOCK" position and disconnect the ABS ECU 18 pin connector.
- Connect a tester to the 13th and 7th 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 terminalsYES
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, rearward).
Inspect the harness and connectors.
- Measure resistance between the 7th and 13th 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, rearward).
Inspect the harness and connectors.
- Disconnect the wheel sensor (right, rearward) 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, rearward)
Replace the wheel sensor.
YES
between the ABS ECU and the wheel sensor (right, rearward).
Inspect the harness and connectors.
- Confirm the DTC P040A is inactive
- Start the engine and let it idling condition.
- Verify the DTC P040A is inactive.
- DTC Clear
- Clear the DTC with Hino DX
- Confirm the same DTC is not reoccurred
- P040A is reoccur: Return to first process
- Other DTC appear: Refer to concerned Trouble shooting
