Inspect for continuity between the following terminals (wiring harness-side) and body ground: SAS control module terminal 1J SAS control module terminal 1M SAS control module terminal 1B SAS control module terminal 1F NOTE: Inspect for continuity while shaking the wiring harness between the SAS control module and driver-side side air bag sensor or passenger-side pressure sensor. Is there continuity?	Yes	Refer to the wiring diagram and verify whether or not there is a common connector between SAS control module terminal and driver-side side air bag sensor or passenger-side pressure sensor terminal. If there is a common connector: Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to ground. Replace the malfunctioning part. If there is no common connector: Replace the wiring harness which has a short to ground. Go to Step 7.
3		No	Go to the next step.
4	INSPECT DRIVER-SIDE SIDE AIR BAG SENSOR CIRCUIT FOR OPEN CIRCUIT Driver-side side air bag sensor and SAS control module connectors are disconnected. Inspect for continuity between the following terminals (wiring harness-side): Driver-side side air bag sensor terminal A-SAS control module terminal 1J Driver-side side air bag sensor terminal B-SAS control module terminal 1M NOTE: Inspect for continuity while shaking the wiring harness between the SAS control module and driver-side side air bag sensor. Is there continuity?	Yes	Go to the next step.
4		No	Refer to the wiring diagram and verify whether or not there is a common connector between SAS control module terminal and driver-side side air bag sensor terminal. If there is a common connector: Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for an open circuit. Replace the malfunctioning part. If there is no common connector: Replace the wiring harness which has an open circuit. Go to Step 7.
5	INSPECT DRIVER-SIDE SIDE AIR BAG SENSOR OR PASSENGER-SIDE PRESSURE SENSOR CIRCUIT FOR SHORT TO OTHER AIR BAG SENSOR CIRCUITS Driver-side side air bag sensor, passenger-side pressure sensor and SAS control module connectors are disconnected. Remove the front bumper. (See FRONT BUMPER REMOVAL/INSTALLATION .) Disconnect the driver and passener-side crash zone sensor connectors.

5		No	Go to the next step.
6	INSPECT DRIVER-SIDE SIDE AIR BAG SENSOR OR PASSENGER-SIDE PRESSURE SENSOR CIRCUIT FOR SHORT TO POWER SUPPLY Driver-side side air bag sensor, passenger-side pressure sensor and SAS control module connectors are disconnected. Connect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION .) Switch the ignition ON (engine off or on). Measure the voltage at the following terminals (wiring harness-side): SAS control module terminal 1J SAS control module terminal 1M SAS control module terminal 1B SAS control module terminal 1F NOTE: Measure the voltage while shaking the wiring harness between the SAS control module and driver-side side air bag sensor or passenger-side pressure sensor. Is the voltage 0 V?	Yes	Replace the driver-side side air bag sensor, then go to the next step. (See SIDE AIR BAG SENSOR REMOVAL/INSTALLATION [TWO-STEP DEPLOYMENT CONTROL SYSTEM - US/CANADA SPEC.] .)
6		No	Refer to the wiring diagram and verify whether or not there is a common connector between SAS control module terminal and driver-side side air bag sensor or passenger-side pressure sensor terminal. If there is a common connector: Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to power supply. Replace the malfunctioning part. If there is no common connector: Replace the wiring harness which has a short to power supply. Go to the next step.
7	PERFORM SAS CONTROL MODULE DTC INSPECTION Switch the ignition off. Disconnect the negative battery terminal and wait for 1 min or more. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION .)

Switch the ignition ON (engine off or on). Clear the DTC for the SAS control module using the M-MDS. (See CLEARING DTC [SAS CONTROL MODULE (TWO-STEP DEPLOYMENT CONTROL SYSTEM - US/CANADA SPEC.)] .) Perform the DTC inspection for the SAS control module using the M-MDS. (See DTC INSPECTION [SAS CONTROL MODULE (TWO-STEP DEPLOYMENT CONTROL SYSTEM - US/CANADA SPEC.)] .) Are the same DTCs present?	Yes	Repeat the inspection from Step 1. If the malfunction recurs, replace the SAS control module. (See SAS CONTROL MODULE REMOVAL/INSTALLATION [TWO-STEP DEPLOYMENT CONTROL SYSTEM - US/CANADA SPEC.] .)
7		No	DTC troubleshooting completed.
