YES : Go to Step 3.

NO : There is an intermittent malfunction such as poor engaged connector(s) or open circuit.

STEP 3. Check SRS-ECU connector C-28, driver's air bag module connector C-205 and clock spring connector C-207. (Using scan tool MB991958, read the diagnostic trouble code.)

Mitsubishi Outlander. Supplemental Restraint System (SRS)

  1. Disconnect the negative battery terminal.
  2. Disconnect connectors C-28, C-205 and C-207, and then reconnect them.

Mitsubishi Outlander. Supplemental Restraint System (SRS)

  1. Connect the negative battery terminal.
  2. Erase the diagnostic trouble code memory, and check the diagnostic trouble code.

Q: Is DTC B1B03 <1st squib> or B1B07 <2nd squib> set?

YES : Go to Step 4.

NO : The procedure is complete. It is assumed that DTC B1B03 <1st squib> or B1B07 <2nd squib> set because connector C-28, C-205 or C-207 was engaged improperly.

STEP 4. Check the driver's air bag module. (Using scan tool MB991958, read the diagnostic trouble code.)

Mitsubishi Outlander. Supplemental Restraint System (SRS)

  1. Disconnect the negative battery terminal.
  2. Slide the outer housing of the C-205 driver's air bag module connector in the arrow direction shown, and disconnect the connector.

Mitsubishi Outlander. Supplemental Restraint System (SRS)

  1. Connect special tool MB991865 to special tool MB991866.

CAUTION Do not insert a probe into the terminal from its front side directly as the connector contact pressure may be weakened.

  1. Insert special tool MB991866 into clock spring side of driver's air bag module connector C-205 (terminal No.1 and 2 <1st squib> or No.3 and 4 <2nd squib>) by backprobing.
  2. Connect the negative battery terminal.

CAUTION Always DTC B1B06 is set when checking DTC B1B03. This is because the second side terminal is isolated when checking it. DTC B1B06 is set but this is not a fault. In addition, always DTC B1B02 is set when checking DTC B1B07 because the first side terminal is isolated.

  1. Erase the diagnostic trouble code memory, and check the diagnostic trouble code.

Q: Is the checked DTC set?

YES : Go to Step 5.

NO : Replace the driver's air bag module. Then go to Step 8.

STEP 5. Check the clock spring. (Using scan tool MB991958, read the diagnostic trouble code.)

Mitsubishi Outlander. Supplemental Restraint System (SRS)

  1. Disconnect the negative battery terminal.
  2. Disconnect the clock spring connector C-207.
  3. Connect special tool MB991865 to special tool MB991866.

CAUTION Do not insert a probe into the terminal from C-207 harness side connector front side directly, as the connector contact pressure may be weakened.

  1. Insert special tool MB991866 into clock spring harness side connector C-207 (terminal No.3 and 4 <1st squib> or No.1 and 2 <2nd squib>) by backprobing.
  2. Connect the negative battery terminal.

CAUTION Always DTC B1B06 is set when checking DTC B1B03. This is because the second side terminal is isolated when checking it. DTC B1B06 is set but this is not a fault. In addition, always DTC B1B02 is set when checking DTC B1B07 because the first side terminal is isolated.

  1. Erase the diagnostic trouble code memory, and check the diagnostic trouble code.

Q: Is the checked DTC set?

YES : Go to Step 6.

NO : Replace the clock spring. Then go to Step 8.

STEP 6. Check the driver's air bag module circuit. Measure the resistance at SRS-ECU connector C-28.

Mitsubishi Outlander. Supplemental Restraint System (SRS)

  1. Disconnect the negative battery terminal.
  2. While pushing the part "A" indicated in the figure of the harness side connector, turn the lock lever to the direction of the arrow to release the lock lever, and disconnect the C-28 SRS-ECU connector.

DANGER To prevent the air bag from deploying unintentionally, disconnect clock spring connector C-207 to short the squib circuit.

  1. Disconnect clock spring connector C-207.

CAUTION Insert an insulator such as a cable tie to a depth of 4mm (0.16 inch) or more, otherwise the short spring will not be released.

  1. Insert a cable tie [3 mm (0.12 inch) wide, 0.5 mm (0.02 inch) thick] between terminals 5, 6 <1st squib> or 9, 10 <2nd squib> and the short spring to release the short spring.

Mitsubishi Outlander. Supplemental Restraint System (SRS)

  1. Check for continuity between C-28 harness side connector terminals 5 and 6 <1st squib> or 9 and 10 <2nd squib>.

    It should be open circuit.

Mitsubishi Outlander. Supplemental Restraint System (SRS)

Q: Is it open circuit?

YES : Erase the diagnostic trouble code memory, and check the diagnostic trouble code. If DTC B1B03 <1st squib> or B1B07 <2nd squib> set, replace the SRS-ECU. Go to Step 8.

NO : Go to Step 7.

STEP 7. Check the harness for short circuit between the harness wire and wire.

Q: the check result normal?

YES : Go to Step 8.

NO : Repair the harness wires between SRS-ECU connector C-28 and clock spring connector C-207.

Then go to Step 8.

STEP 8. Recheck for diagnostic trouble code.

Check again if the DTC is set.

Mitsubishi Outlander. Supplemental Restraint System (SRS)

  1. Erase the DTC.
  2. Turn the ignition switch to the "ON" position.
  3. Check if the DTC is set.
  4. Turn the ignition switch to the "LOCK" (OFF) position.

Q: Is DTC B1B03 <1st squib> or B1B07 <2nd squib> set?

YES : Return to Step 1.

NO : The procedure is complete.
