Failure Mode C

Failure Mode B: Cowl Sensor Short or Dash Sensor Open

Fig. 2 Passenger Side Short Connector Location:

1. Connect test harness B between SRS system unit and main harness connector, then measure resistance between terminals B1 and B7. If resistance is more than 200 ohm, proceed to ``Mode E'' diagnosis. If resistance is less than 200 ohms, disconnect battery negative and positive terminals, then connect the short connector to the airbags assembly, Fig. 2. Measure resistance between left dash sensor terminals B12 and B16, and between right dash sensor terminals B4 and B6. If resistance is more than 5000 ohms, go to step 2. If resistance is less than 5000 ohms, the SRS unit is defective. Replace as necessary.
2. Connect test harness D between dash sensor and SRS main harness 2-P connector. Measure resistance between No. 1 and No. 2 terminals. If resistance is more than 5000 ohms, the respective dash sensor is defective. Replace as necessary. If resistance is less than 5000 ohms, SRS main wire harness is defective. Replace as necessary.
