Action Taken
DERM turns on INFLATABLE RESTRAINT indicator light.
NOTE:
Test numbers refer to test numbers on diagnostic chart. For circuit number identification, see WIRING DIAGRAMS.
WARNING:
To avoid air bag deployment while troubleshooting the SIR system, only use test equipment specified in diagnostic charts. Under no circumstances should battery powered test equipment or test light be used. Carefully follow all instructions.
- Checks for short to ground in DRIVER SOURCE SENSE circuit between DERM and dual pole arming sensor.
- Checks for an open in DRIVER SOURCE SENSE circuit.
- Checks for a short to 5 volts on DRIVER SOURCE SENSE circuit.
- Checks for proper connector terminal contact at DERM and dual pole arming sensor connectors.
- Checks dual pole arming sensor for an open 2490-ohm resistor by measuring for correct voltage.
