Failure Mode G




Mode G: Open in front passenger's airbag inflator.

NOTES:
- Before you disconnect the battery, be sure you get the customer's anti-theft radio code number.
- Do not disconnect the front passenger's airbag connector for the following test.

CAUTION:
- Disconnect the battery negative cable and then disconnect the positive cable.
- Before disconnecting the driver's airbag connector, turn off the ignition switch and wait for at least 3 minutes to let the capacitor in the backup 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 driver's airbag. and both seat belt pretensioners. After installing the short connector on the driver's airbag, immediately install a Short Connector "A" (Tool Number O7MAZ-5P00200) on the cable reel connector. 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.






2. Measure the resistance between the No.2 terminal and No.8 terminal.






- If resistance is more than 0.2K ohms, go to step 3.

- If resistance is less than 0.2K 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.

3. Disconnect the front passenger's airbag 3-P connector from the SRS main harness, then connect Test Harness C to the front passenger's airbag side of the connector.






4. Measure the resistance between the No.9 terminal and the No. 10 terminal.






- If resistance is more than 0.2K ohms, the front passenger's airbag inflator is faulty. Replace the front passenger's airbag assembly and recheck the voltages according to the chart in the "Indicator Stays On Continuously" procedure.

- If resistance is less than 0.2K ohms, 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.
