C0236 ABNORMALITY OF SOLENOID FOR FRONT LEFT WHEEL

1. Firstly, perform the check of "DISCONNECTION OF SOLENOID RELAY (DTC No.C0278)".

1. Set the starter switch to "LOCK", disconnect the 24 pin connector of ABS actuator..
2. Measure the resistance between 16th and 22th terminals of the 24 pin connector (actuator side).
   Standard: 26-40 Ω
   
   
   　

Abnormality of the ABS actuator.

[2]-3

3. Measure the resistance between 15th and 16th terminals of the 24 pin connector (actuator side).
   Standard: 13-20 Ω
   
   
   　

Abnormality of the ABS actuator.

[3] WIRE HARNESS CHECK

1. Disconnect the 31 pin connector of ECU.
2. Measure the resistance between 8th terminal of the 31 pin connector of ECU (chassis harness side) and 22th terminal of the 24 pin connector of ABS actuator (chassis harness side).
   Standard: Less than 5 Ω
   
   
   　

Abnormality of the wire harness.

[3]-3

3. Measure the resistance between 9th terminal of the 31 pin connector of ECU (chassis harness side) and 15th terminal of the 24 pin connector of ABS actuator (chassis harness side).
   Standard: Less than 5 Ω
   
   

   　

Abnormality of the wire harness.

[4] ECU CHECK.

1. Connect all the connector, turn the starter switch to "ON".
2. Measure the voltage between 8th and 2nd terminals of the 31 pin connector of ECU. (Leaving the connector connected with ECU.)
   Standard: 20-28V
   
   
   　

Abnormality of the ECU power supply voltage.

[4]-3

3. Measure the voltage between 9th and 2nd terminals of the 31 pin connector. (Leaving the connector connected with ECU.)
   Standard: 20-28V
   
   

   　

Abnormality of the ECU power supply voltage.

Normal.

1. Confirm the DTC C0236 is inactive

   • Start the engine and let it idling condition.
   • Verify the DTC C0236 is inactive.

   

2. DTC Clear

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

   

C0236 is reoccur: Return to first process Other DTC appear: Refer to concerned Trouble shooting
