Failure Mode E

Failure Mode E: Open In Driver's Airbag Inflater or Cable Reel

NOTE:
The radio may have a five-digit coded theft protection circuit. Be sure to get the customer's code number before disconnecting the battery cables.

1. Before disconnecting any part of the SRS wire harness, install the short connector(s),

Test Harness B Connector Pinout:

2. Connect Test Harness B (07MAZ - SF00500) between the SRS unit and the SRS main harness 18-P connector.

(Without front passenger's airbag: DE type)
Reconnect the driver's airbag connector, then check the resistance between terminals B4 and B6, and between terminals B12 and B16.
- If the resistance is more than 5.0 Kohm for either set of terminals, go to mode C troubleshooting.
- If resistance is less than 5.0 Kohm for both sets of terminals, go to step 3.

Test Harness B Connector Pinout:

3. Check the resistance between the B1 and B7 terminals.
- If resistance is more than 0.2 Kohm, go to step 4.
- If resistance is less than 0.2 Kohm, the SRS unit is faulty. Substitute a known-good SRS unit and recheck the voltages according to the appropriate Failure Mode Diagnostic Chart. Refer to Failure Mode Diagnostic Chart.

Installation Of Test Harness C:

4. Disconnect the cable reel 6-P connector from the SRS main harness, then connect Test Harness C (O7LAZ - SL40300) only to the cable reel side of the connector.

Test Harness C Connector Pinout:

5. Measure the resistance between the No. 4 terminal and the No. 5 terminal.
- If resistance is more than 0.2 Kohm, go to step 6.
- If resistance is less than 0.2 Kohm, the SRS main harness is faulty. Replace it and recheck the voltages according to the appropriate Failure Mode Diagnostic Chart. Refer to Failure Mode Diagnostic Chart.

Installation Of Test Harness C:

6. Disconnect the driver's airbag 3-P connector from the cable reel, then connect Test Harness C (O7LAZ - SL40300) to the driver's airbag 3-P connector.

Test Harness C Connector Pinout:

7. Measure the resistance between the No. 7 terminal and the No.8 terminal.
- If resistance is more than 0.2 Kohm, the driver's airbag inflator is faulty. Replace the airbag assembly and recheck the voltages according to the appropriate Failure Mode Diagnostic Chart. Refer to Failure Mode Diagnostic Chart.
- If resistance is less than 0.2 Kohm, the cable reel is faulty. Replace it and recheck the voltages according to the appropriate Failure Mode Diagnostic Chart. Refer to Failure Mode Diagnostic Chart.
