Failure Mode D
Failure Mode D: Cowl Sensor Short or Dash Sensor Open1. Before disconnecting any part of the SRS wire harness, install the short connector(s) (RED) on the airbag(s).
Test Harness B Installation And Testing:
2. Connect Test Harness B (O7MAZ-SPOO5OO) between the SRS unit and SRS main harness 18-P connector.
Test Harness B Pinout:
3. Check the resistance between the left dash sensor terminals B12 and B16, and between the right dash sensor terminals B4 and B6.
- If resistance is more than 5 Kohm for either set of terminals, go to step 4.
- If resistance is less than 5 Kohm for both sets of terminals, 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 D Installation And Testing:
4. Connect Test Harness D (O7LAZ-SL40400) between the dash sensor and SRS main harness 2-P connector. Check the resistance between the No. 1 terminal and No. 2 terminal.
- If resistance is more than 5 Kohm, the dash sensor is faulty. Replace it and recheck the voltages according to the appropriate Failure Mode Diagnostic Chart. Failure Mode Diagnostic Chart
- If resistance is less than 5 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
