Failure Mode C and D

Mode C: Short in cowl sensor, or open in dash sensor.

Mode D: Open in one dash sensor.

NOTE: Before you disconnect the battery, be sure you get the customer's anti-theft radio code number.

CAUTION:
- Disconnect the battery negative cable and then disconnect the positive cable.
- Before disconnecting the airbag connector(s), turn off the ignition switch and wait for at least 3 minutes to let the capacitor in the back-up circuit discharge. This will prevent a malfunction of the seat belt pretensioners.
- Before disconnecting any part of the SRS wire harness, install short connectors (RED) on the air- bag(s). and both seat belt pretensioners. After installing the short connector(s) on the airbag(s), immediately install one Short Connector "A" (Tool Number O7MAZ-SPOO2OO) on the cable reel connector (for the driver's airbag), and another on the SRS main harness connector (for the passenger's airbag). This will prevent any static electricity from triggering the seat belt pretensioners before you disconnect them - refer to "Short Connector Installation" procedure.

1. Connect Test Harness B between the SRS unit and SRS main harness 18-P connector.
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 5K ohms, go to step 2.

- If resistance is less than 5K ohms, the SRS unit is faulty. Substitute a known-good SRS unit and recheck the voltages according to the chart in the "Indicator Stays On Continuously" procedure.

2. Connect Test Harness D 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 5K ohms, the dash sensor is faulty. Replace and recheck the voltages according to the chart in the "Indicator Stays On Continuously" procedure.

- If resistance is less than 5 K(2, the SRS main harness is faulty. Replace the SRS main harness and recheck the voltages according to the chart in the "Indicator Stays On Continuously" procedure.
