C0200 ABNORMALITY OF FRONT RIGHT WHEEL SENSOR

1. Perform the following checks:
   
   • No damage at the sensor tip.
   • No adhesion of foreign material of more than 1 mm³.
   • No clearance between sensor and the face to be installed.
   • No air gap expansion between sensor and sensor rotor.
     Standard: No abnormality

Repair or replace the sensor installing part.

[1]-2

2. Set the starter switch to "LOCK", disconnect the 31 pin connector of ECU.
3. Measure the resistance between 25th and 26th terminals of the 31 pin connector (chassis harness side).
   Standard: 0.8-2.0 kΩ
   
   
   　

Go to the item "3".

[2] ECU CHECK

1. Connect the connector, check the continuity between 2nd and 25th terminals of the 31 pin connector of ECU. (Leaving the connector connected with ECU.)
   Standard: Continuity
   
   
   　

Abnormality of the ECU.

[2]-2

2. Connect oscilloscope between 2nd and 26th terminals of the 31 pin connector, measure any waveform to be output when running at speed of 30 km/h {19 mile/h}. (Leaving the connector connected with ECU.)
   Standard: Waveform output
   
   
   　

Abnormality of the ECU.

Normal.

1. Disconnect the connector of front right wheel sensor.
2. Measure the resistance between 26th terminal of the 31 pin connector of ECU (chassis harness side) and 1st terminal of the sensor connector (chassis harness side).
   Standard: Less than 5 Ω
   
   
   　

Abnormality of the wire harness.

[3]-3

3. Measure the resistance between 25th terminal of the 31 pin connector of ECU (chassis harness side) and 2nd terminal of the sensor connector (chassis harness side).
   Standard: Less than 5 Ω
   
   

　

Abnormality of the wire harness.

[4] SENSOR CHECK

1. Measure the resistance between 1st and 2nd terminals of the connector of front right wheel sensor (sensor side).
   Standard: 0.8-2.0 kΩ
   
   

　

Abnormality of the sensor.

Normal.

1. Confirm the DTC C0200 is inactive

   • Start the engine and let it idling condition.
   • Verify the DTC C0200 is inactive.

   

2. DTC Clear

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

   

C0200 is reoccur: Return to first process Other DTC appear: Refer to concerned Trouble shooting
