DTC 41: IG1 Power Supply Circuit System (Fuse No.23 Circuit): 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 junction block multi-purpose fuse number 23. 

    Q: Is the fuse burned out? 

    YES  : Go to  Step 4.

      CAUTION: Do not insert a test probe into the terminal from its front side directly as the connector contact pressure may be weakened.
    5. Measure the voltage between the C-137 harness side connector terminal 12 and body ground. Voltage should be 9 volts or more.

    Q: Is the measured voltage within the specified range? 

    YES  : Erase the DTC memory, and recheck if any DTC sets. If DTC 41 sets, replace the SRS-ECU (Refer to SRS CONTROL UNIT (SRS-ECU)  ). Then go to  Step 10.

    NO:  Go to Step 3.

  3. STEP 3. Check the harness wire for open circuit between the SRS-ECU connector C-137 (terminal No.12) and the ignition switch connector C-202 (terminal No.2). 
    NOTE: After inspecting the intermediate connectors C-308 and C-311, inspect the wiring harness. If the intermediate connector C-308 or C-311 is damaged, repair or replace it. Refer to , HARNESS CONNECTOR INSPECTION . Then go to  Step 10.

  4. STEP 4. Check a burned-out fuse. 
    1. Replace the fuse.
    2. Turn the ignition switch to the "ON" position, wait for at least one minute and then turn the ignition switch to the "LOCK" (OFF) position.
    3. Check the fuse.

    Q: Is the fuse in good condition? 

    YES  : Go to  Step 10.

    NO:  Go to Step 5.

  5. STEP 5. Check the SRS-ECU power supply circuit for short circuit to ground at the junction block connector C-308. 
    1. Disconnect the junction block connector C-308, and measure at the harness side connector.

      CAUTION: Do not insert a test probe into the terminal from its front side directly as the connector contact pressure may be weakened.
    2. Check for continuity between the terminal 24 and body ground.

      It should be open circuit.

    Q: Does continuity exist? 

    YES  : Go to  Step 8.

    NO:  Go to Step 6.

      CAUTION: Do not insert a test probe into the terminal from its front side directly as the connector contact pressure may be weakened.
    2. Check for continuity between terminals 25 and body ground.

      It should be open circuit.

    Q: Does continuity exist? 

    YES  : Go to Step 7.

    NO:  Check the other circuit, which flows through fuse number 23.

  7. STEP 7. Check the harness wire for short circuit to ground between the junction block connector C-308 (terminal No.25) and the combination meter connector C-101 (terminal No.12). 

    Q: Is the harness wire between the junction block connector C-308 (terminal No.25) and the combination meter connector C-101 (terminal No.12) in good condition? 

    YES  : Go to  Step 10.

    NO:  Repair the harness wire between the junction block connector C-308 and the combination meter connector C-101. Then go to  Step 10.

      CAUTION: Do not insert a test probe into the terminal from its front side directly as the connector contact pressure may be weakened.
    3. Check for continuity between the terminal 12 and body ground.

      It should be open circuit.

    Q: Is the circuit normal? 

    YES  : Go to Step 9.

    NO:  Erase the DTC memory, and recheck if any DTC sets, If DTC 41 sets, replace the SRS-ECU (Refer to SRS CONTROL UNIT (SRS-ECU)  ). Then go to  Step 10.
