NOTE: When the measured resistance value is more than 52 Ω and less than 62 Ω, main wiring harness or related lines may be shorted to ground, or shorted to power supply line, or related lines may be open.
  1. CHECK BETWEEN RELATED LINES AND MAIN WIRING HARNESS  .
    1. Turn the ignition switch to OFF.
    2. Disconnect the steering angle sensor connector.
    3. Use a tester to measure the resistance between the steering angle sensor connector and chassis ground.

      Connector & terminal 

      (i74) No. 2 - Chassis ground:

      (i74) No. 3 - Chassis ground:

      Is the resistance less than 10 Ω?

      Yes  : Go to  2.

      No  : Go to  3.

  2. CHECK CONTROL MODULE  .

    With the tester connected, disconnect control module.

    NOTE: Disconnect the body integrated unit at the end.

    Connector & terminal 

    (i74) No. 2 - Chassis ground:

    (i74) No. 3 - Chassis ground:

    Did the resistance change to 10 Ω or more?

    Yes  : Replace the control module whose resistance has changed. When the value changed at disconnecting the body integrated unit, replace the body integrated unit. Ref. to SECURITY AND LOCKS>Body Integrated Unit>REMOVAL .

    Go to  3.

    No  : Repair or replace the short circuit of the harness between body integrated unit and ECM.

  3. CHECK BETWEEN RELATED LINES AND MAIN WIRING HARNESS  .
    1. Turn the ignition switch to ON.
    2. Use a tester to measure the voltage between the steering angle sensor connector and chassis ground.

      Connector & terminal 

      (i74) No. 2 (+) - Chassis ground (-):

      (i74) No. 3 (+) - Chassis ground (-):

      Is the voltage 5 V or less?

      Yes  : CAN communication circuit is normal.

      No  : Go to  4.

  4. CHECK CONTROL MODULE  .

    With the tester connected, disconnect control module.

    NOTE: Disconnect the body integrated unit at the end.

    Connector & terminal 

    (i74) No. 2 (+) - Chassis ground (-):

    (i74) No. 3 (+) - Chassis ground (-):

    Did the voltage change to 5 V or less?

    Yes  : Replace the control module whose voltage has changed. When the value changed at disconnecting the body integrated unit, replace the body integrated unit. Ref. to SECURITY AND LOCKS>Body Integrated Unit>REMOVAL .

    Go to  5.

    No  : Repair or replace the short circuit of the harness between body integrated unit and ECM.

  5. CHECK HARNESS  .

    Measure the voltage between body integrated unit connector and chassis ground using tester.

    Connector & terminal 

    (i171) No. 1 (+) - Chassis ground (-):

    (i171) No. 2 (+) - Chassis ground (-):

    Is the voltage 5 V or less?

    Yes  : CAN communication circuit is normal.

    No  : Repair or replace the short circuit of the harness between ECM - body integrated unit.
