INSPECTION PROCEDURE O-19: ETACS-ECU does not receive a interior light loaded signal.: 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 battery power supply circuit to the ETACS-ECU. Test at ETACS-ECU connector C-319. 
    1. Disconnect ETACS-ECU connector C-319 and measure the voltage available at the junction block side of the connector.

    2. Measure the voltage between terminal 20 and ground.
      • The voltage should equal approximately 12 volts (battery positive voltage).

    Q: Is the measured voltage approximately 12 volts (battery positive voltage)? 

    YES  : Go to  Step 4.

    NO:  Go to Step 2.

  2. STEP 2. Check the ETACS-ECU connector C-319 for loose, corroded or damaged terminals, or terminals pushed back in the connector. 

    Q: Is ETACS-ECU connector C-319 in good condition? 

    YES  : Go to Step 3.

    NO:  Repair or replace the damaged component(s). Refer to , HARNESS CONNECTOR INSPECTION . The functions, which are described in the "TECHNICAL DESCRIPTION (COMMENT) ," should work normally.

    NOTE: Also check junction block connector C-312, joint connector C-141 and intermediate connector C-209 for loose, corroded, or damaged terminals, or terminals pushed back in the connector. If junction block connector C-312, joint connector C-141 or intermediate connector C-209 is damaged, repair or replace the damaged component(s) as described in , HARNESS CONNECTOR INSPECTION .

    Q: Is the wiring harness between ETACS-ECU connector C-319 (terminal 20) and the battery in good condition? 

    YES  : No action is necessary and testing is complete.

    NO:  Repair the wiring harness. If the functions or equipment, which are described in "CIRCUIT OPERATION ", work normally, the interior light loaded signal should be normal.

    3. Measure the voltage between terminal 8 and ground.
      • The voltage should equal approximately 12 volts (battery positive voltage).

    Q: Is the measured voltage approximately 12 volts (battery positive voltage)? 

    YES  : Go to  Step 7.

    NO:  Go to Step 5.
