DIAGNOSTIC PROCEDURE CHART

Step Check Yes No
1 CHECK POWER SUPPLY FOR STEERING ANGLE SENSOR. 
  1. Turn the ignition switch to OFF.
  2. Disconnect the connector from steering angle sensor.
  3. Turn the ignition switch to ON.
  4. Measure the voltage between steering angle sensor and chassis ground.

    Connector & terminal 

    (B231) No. 4 (+) - Chassis ground (-): 

 Is the voltage 10 - 15 V? Go to step 2.  Repair the steering angle sensor power supply circuit.
2 CHECK GROUND CIRCUIT OF STEERING ANGLE SENSOR. 
Measure the resistance between steering angle sensor and chassis ground.
Connector & terminal 
(B231) No. 3 - Chassis ground: 		 Is the resistance less than 10 Ω? Go to step 3.  Repair ground circuit in the steering angle sensor.
3 CHECK STEERING ANGLE SENSOR HARNESS. 
  1. Disconnect the connector from the VDCCM&H/U.
  2. Measure the resistance between VDCCM&H/U and steering angel sensor.

    Connector & terminal 

    (B231) No. 1 - (B310) No. 10: 

    (B231) No. 2 - (B310) No. 35: 

 Is the resistance less than 1 Ω? Go to step 4.  Repair the harness between the steering angle sensor and VDCCM&H/U.
4 CHECK GROUND SHORT CIRCUIT OF STEERING ANGLE SENSOR HARNESS. 
Measure the resistance between steering angle sensor and chassis ground.
Connector & terminal 
(B231) No. 1 - Chassis ground: 
(B231) No. 2 - Chassis ground: 		 Is the resistance 1 MΩ or more? Go to step 5.  Repair the harness between the steering angle sensor and VDCCM&H/U.
5 CHECK STEERING ANGLE SENSOR. 
  1. Turn the ignition switch to OFF.
  2. Connect all connectors.
  3. Clear the memory. < Ref. to CLEAR MEMORY MODE . >
  4. Perform the Inspection Mode. < Ref. to INSPECTION MODE . >
  5. Read the DTC.
 Is the same DTC displayed? Go to step 6.  Go to step 7  .
6 CHECK VDCCM&H/U. 
  1. Turn the ignition switch to OFF.
  2. Replace the steering angle sensor. < Ref. to STEERING ANGLE SENSOR . >
  3. Clear the memory. < Ref. to CLEAR MEMORY MODE . >
  4. Perform the Inspection Mode. < Ref. to INSPECTION MODE . >
  5. Read the DTC.
 Is the same DTC displayed? Replace the VDCCM only. < Ref. to REPLACEMENT , VDC Control Module and Hydraulic Control Unit (VDCCM&amp;H/U). > Go to step 8  .
7 CHECK OTHER DTC DETECTION.  Is any other DTC displayed? Perform the diagnosis according to DTC. < Ref. to LIST OF DIAGNOSTIC TROUBLE CODE (DTC) . > Temporary poor contact occurs.
8 CHECK OTHER DTC DETECTION.  Is any other DTC displayed? Perform the diagnosis according to DTC. < Ref. to LIST OF DIAGNOSTIC TROUBLE CODE (DTC) . > Original steering angle sensor malfunction
