1. Set the starter key to the "LOCK" position and disconnect the auxiliary brake cut relay.
   
   

   

   
   

   

2. Turn the starter key "ON" and measure voltage between the auxiliary brake cut relay connector and a GND on the vehicle body.
   
   

   

   Standard value: 20 V or more
   

NO Disconnection of harness between ABS 10 A fuse and auxiliary brake cut relay Inspect the harness.

YES Proceed to [2] Measuring continuity between terminals

1. Set the starter key to the "LOCK" position and disconnect the ABS ECU 15 pin connector.
2. Measure continuity between the 6th terminal of the 15 pin connector (vehicle harness side) and a terminal of the auxiliary brake cut relay connector.
   
   

   Standard: With continuity

NO Disconnection of harness between ABS ECU and auxiliary brake cut relay Inspect the harness.

YES Proceed to [3] Measuring continuity between terminals

1. Measure resistance between terminals of the auxiliary brake cut relay.
   
   

   Standard value: 370-540 Ω

NO Abnormality in auxiliary brake cut relay

YES Normal now. Short-lived disconnection is likely to have occurred in the harnesses between the ABS ECU and the auxiliary brake cut relay or between the auxiliary brake cut relay and the ABS 10 A fuse. Inspect the harness and connectors.

1. Confirm the DTC P0D05 is inactive

   • Start the engine and let it idling condition.
   • Verify the DTC P0D05 is inactive.

   

2. DTC Clear

   • Clear the DTC with Hino DX
   • Confirm the same DTC is not reoccurred

   

P0D05 is reoccur: Return to first process Other DTC appear: Refer to concerned Trouble shooting
