    3. Connect special tool MB991865 to special tool MB991866.
      CAUTION: Do not insert a test probe into the terminal from its front side directly as the connector contact pressure may be weakened.
    4. Insert special tool MB991866 into the clock spring harness side connector C-204 (terminal No.3 and 4) by backprobing.
    5. Connect the negative battery terminal.
    6. Erase the DTC memory, and then recheck the DTC.

    Q: Is DTC 61 set? 

    YES  : Go to  Step 3.

    NO:  Go to Step 2.

  2. STEP 2. Check the clock spring and the driver's air bag module. 
    1. Disconnect the negative battery terminal.
    2. Connect connector (4) of special tool MB991613 to clock spring connector C-208.
    3. Connect connector (1) of special tool MB991613 to connector (2).
    4. Connect terminals 22 to 24, and terminals 23 to 25 of special tool MB991613 to connector (5).
    5. Connect the clock spring to the instrument panel wiring harness.
    6. Connect the negative battery terminal.
    7. Erase the DTC memory, and then recheck the DTC.

    Q: Is DTC 61 set? 

    YES  : Replace the clock spring (Refer to AIR BAG MODULES AND CLOCK SPRING  ). Then 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.
    4. Measure the voltage between the C-137 harness side connector terminals 7, 8 and body ground.

      Voltage should be 0 volt.

    Q: Is the measured voltage within the specified range? 

    YES  : Erase the DTC memory, and recheck if any DTC sets. If DTC 61 sets, replace the SRS-ECU (Refer to SRS CONTROL UNIT (SRS-ECU)  ). Then go to  Step 5.

    NO:  Go to Step 4.

  4. STEP 4. Check the harness wires for short circuit to power supply between the SRS-ECU connector C-137 (terminal No.7 and 8) and the clock spring connector C-204 (terminal No.3 and 4). 

    Q: Are the harness wires between the SRS-ECU connector C-137 (terminal No.7 and 8) and the clock spring connector C-204 (terminal No.3 and 4) in good condition? 

    YES  : Go to Step 5.

    NO:  Repair the harness wires between the SRS-ECU connector C-137 and clock spring connector C-204. Then go to Step 5.
