INSPECTION PROCEDURE O-7: The driver's seat belt switch is not sent to the ETACS-ECU.: Diagnosis

WARNING: This page is about a different car, the 2005 Dodge Stratus and 2005 Chrysler Sebring. However, it is still accessible from the selected car via links, so may be relevant.

Required Special Tools: 

  1. STEP 1. Check the driver's seat belt switch. 
    TESTER CONNECTION SPECIFIED CONDITION CHART

    ITEM TESTER CONNECTION SPECIFIED CONDITION
    Fastened seat belt 1 - 2 Open circuit
    Unfastened seat belt 1 - 2 Less than 2 ohms

    Q: Is the driver's seat belt switch in good condition? 

    YES  : Go to Step 2.

    NO:  Replace the driver's inner seat belt. The driver's seat belt switch input signal should be able to be checked and the functions, which are described in the "TECHNICAL DESCRIPTION (COMMENT) ," should work normally.

    2. Measure the resistance between terminal 2 and ground.
      • The resistance should equal 2 ohms or less.

    Q: Is the measured resistance 2 ohms or less? 

    YES  : Go to  Step 5.

    NO:  Go to Step 3.
