    2. Disconnect the D58 yaw rate sensor connector.
    3. Measure the resistance according to the value(s) in the table below.

      Standard Resistance

      Tester Connection Switch Condition Specified Condition
      D58-3 (CANH) - D58-2 (CANL) Ignition switch off 54 to 69 Ω

      (to Yaw Rate Sensor)
    4. Reconnect the yaw rate sensor connector.

    NG → REPAIR OR REPLACE CAN BRANCH WIRE OR CONNECTOR (CAN-H, CAN-L) 

    OK: Go to next step 

  2. CHECK HARNESS AND CONNECTOR (YAW RATE SENSOR - BATTERY AND BODY GROUND) 
    1. Disconnect the D58 yaw rate sensor connector.

    2. Measure the resistance according to the value(s) in the table below.

      Standard Resistance

      Tester Connection Condition Specified Condition
      D58-1 (GND) - Body ground Always Below 1 Ω
    3. Measure the voltage according to the value(s) in the table below.

      Standard Voltage

      Tester Connection Switch Condition Specified Condition
      D58-4 (IG) - Body ground Ignition switch ON 11 to 14 V

      *a Front view of wire harness connector
      (to Yaw Rate Sensor)
    4. Reconnect the yaw rate sensor connector.

    NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

    OK → See step   3 

  3. REPLACE YAW RATE SENSOR. Refer to  REMOVAL
