CAUTION / NOTICE / HINT

Tech Tips

Inspect the fuses for circuits related to this system before performing the following procedure.

PROCEDURE


  1. INSPECT BATTERY VOLTAGE


    1. Measure the battery voltage.

      Standard voltage
      11 to 14 V

      Tech Tips

      If the voltage is below 11 V, recharge or replace the battery before proceeding to the next step.

    2. Check the connector connections and terminals to make sure that there are no abnormalities such as loose connections, deformation, etc.

      Tester Connection Condition Specified Condition
      Y30-40 (+B) - Body ground Always 11 to 14 V
      Y31-2 (+B1) - Body ground Always 11 to 14 V
      Y29-2 (+B2) - Body ground Always 11 to 14 V
      Y30-20 (IG) - Body ground Engine switch off Below 1 V
      Engine switch on (IG) 11 to 14 V
      for Rear RH Side
      Tester Connection Condition Specified Condition
      Y10-40 (+B) - Body ground Always 11 to 14 V
      Y11-2 (+B1) - Body ground Always 11 to 14 V
      Y9-2 (+B2) - Body ground Always 11 to 14 V
      Y10-20 (IG) - Body ground Engine switch off Below 1 V
      Engine switch on (IG) 11 to 14 V

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

      Standard Resistance
      for Rear LH Side
      Tester Connection Condition Specified Condition
      Y31-10 (GND1) - Body ground Always Below 1 Ω
      Y29-10 (GND2) - Body ground Always Below 1 Ω
      Y30-38 (E) - Body ground Always Below 1 Ω
      for Rear RH Side
      Tester Connection Condition Specified Condition
      Y11-10 (GND1) - Body ground Always Below 1 Ω
      Y9-10 (GND2) - Body ground Always Below 1 Ω
      Y10-38 (E) - Body ground Always Below 1 Ω
