On-Vehicle Inspection

  1. DISCONNECT CABLE FROM NEGATIVE BATTERY TERMINAL 
    CAUTION: Wait at least 90 seconds after disconnecting the cable from the negative (-) battery terminal to prevent airbag and seat belt pretensioner activation.
  2. INSPECT CIRCUIT OPENING RELAY 
    1. Measure the resistance between the terminals.

    Standard resistance 

    TESTER CONNECTION SPECIFIED CONDITION CHART

    Tester Connection Specified Condition
    1B (11) - 1A (8) 10 kΩ or higher
    1B (11) - 1A(8) Below 1 Ω (when battery voltage is applied to terminals 1E (5) and 1D (1))

    If the result is not as specified, replace the instrument panel junction block.

  3. CONNECT CABLE TO NEGATIVE BATTERY TERMINAL 
  4. PERFORM INITIALIZATION 
    1. Perform initialization (see INITIALIZATION ).
    NOTE: Certain systems need to be initialized after disconnecting and reconnecting the cable from the negative (-) battery
