Failure Mode E

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

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

Test Harness D Installation And Testing:

2. Connect Test Harness B (O7MAZ-SPOO5OO) between the SRS unit and the SRS main harness 18-P connector.

Test Harness B Installation And Testing:

3. Reconnect the driver's airbag connector, then measure 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. Failure Mode Diagnostic Chart

Test Harness C Installation:

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 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. Failure Mode Diagnostic Chart

Test Harness C Installation And Testing:

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 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. 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. Failure Mode Diagnostic Chart
