Diagnostic Procedure

Step	Inspection		Action
1	INSPECT PASSENGER-SIDE CRASH ZONE SENSOR Warning •  Handling the component parts improperly can accidentally operate (deploy) the air bag modules, pre-tensioner seat belts and active bonnet actuators (with active bonnet) which may seriously injure you. Read the service warnings/cautions and the workshop manual before handling the air bag system components. (See AIR BAG SYSTEM SERVICE WARNINGS.) (See AIR BAG SYSTEM SERVICE CAUTIONS.) (See ACTIVE BONNET SERVICE WARNINGS.) (See ACTIVE BONNET SERVICE CAUTIONS.) •  Switch the ignition off. •  Disconnect the negative battery cable and wait for 1 min or more. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION.) •  Verify that the passenger-side crash zone sensor is correctly installed. (See CRASH ZONE SENSOR REMOVAL/INSTALLATION.) •  Is the passenger-side crash zone sensor correctly installed?	Yes	Go to the next step.
		No	Correctly install the passenger-side crash zone sensor. (See CRASH ZONE SENSOR REMOVAL/INSTALLATION.) Then go to the next step.
2	INSPECT PASSENGER-SIDE CRASH ZONE SENSOR CONNECTOR •  Switch the ignition off. •  Disconnect the negative battery cable and wait for 1 min or more. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION.) •  Remove the front bumper. (See FRONT BUMPER REMOVAL.) •  Disconnect the passenger-side crash zone sensor connector. (See CRASH ZONE SENSOR REMOVAL/INSTALLATION.) •  Inspect the passenger-side crash zone sensor connector. (Corrosion, damage, and disconnected pins) •  Is there any malfunction of the passenger-side crash zone sensor connector?	Yes	Replace the malfunction part, then go to step 6.
		No	Go to the next step.
3	INSPECT PASSENGER-SIDE CRASH ZONE SENSOR CIRCUIT FOR SHORT TO GROUND •  Remove the column cover. (See COLUMN COVER REMOVAL/INSTALLATION.) •  Disconnect the clock spring connector. (See CLOCK SPRING REMOVAL/INSTALLATION.) •  Remove the passenger-side lower panel. (See PASSENGER-SIDE LOWER PANEL REMOVAL/INSTALLATION.) •  Disconnect the passenger-side air bag module connector. (See PASSENGER-SIDE AIR BAG MODULE REMOVAL/INSTALLATION.) •  Disconnect the driver and passenger-side seat connectors. (See SEAT REMOVAL/INSTALLATION.) •  Remove the back trim. (See BACK TRIM REMOVAL/INSTALLATION.) •  Disconnect the driver and passenger-side pre-tensioner seat belt connectors. (See SEAT BELT REMOVAL/INSTALLATION.) •  Disconnect the driver and passenger-side lap pre-tensioner seat belt connectors. (See SEAT BELT REMOVAL/INSTALLATION.) •  Disconnect the active bonnet actuator connector. (with active bonnet) (See ACTIVE BONNET ACTUATOR REMOVAL/INSTALLATION.) •  Disconnect the all SAS control module connectors. (See SAS CONTROL MODULE REMOVAL/INSTALLATION.) •  Inspect for continuity between the following terminals (wiring harness-side) and body ground: ―  SAS control module terminal 2H ―  SAS control module terminal 2L Note •  Inspect for continuity while shaking the wiring harness between the SAS control module and passenger-side crash zone 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 passenger-side crash zone 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 6.
		No	Go to the next step.
4	INSPECT PASSENGER-SIDE CRASH ZONE SENSOR CIRCUIT FOR OPEN CIRCUIT •  Passenger-side crash zone sensor and SAS control module connectors are disconnected. •  Inspect for continuity between the following terminals (wiring harness-side): ―  Passenger-side crash zone sensor terminal A—SAS control module terminal 2H ―  Passenger-side crash zone sensor terminal B—SAS control module terminal 2L Note •  Inspect for continuity while shaking the wiring harness between the SAS control module and passenger-side crash zone sensor. •  Is there continuity?	Yes	Go to the next step.
		No	Refer to the wiring diagram and verify whether or not there is a common connector between SAS control module terminal and passenger-side crash zone 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 6.
5	INSPECT PASSENGER-SIDE CRASH ZONE SENSOR CIRCUIT FOR SHORT TO POWER SUPPLY •  Passenger-side crash zone sensor and SAS control module connectors are disconnected. •  Connect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION.) •  Switch the ignition ON (engine off or on). •  Measure the voltage at the following terminals (wiring harness-side): ―  SAS control module terminal 2H ―  SAS control module terminal 2L Note •  Measure the voltage while shaking the wiring harness between the SAS control module and passenger-side crash zone sensor. •  Is the voltage 0 V?	Yes	Replace the passenger-side crash zone sensor, then go to the next step. (See CRASH ZONE SENSOR REMOVAL/INSTALLATION.)
		No	Refer to the wiring diagram and verify whether or not there is a common connector between SAS control module terminal and passenger-side crash zone 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.
6	PERFORM SAS CONTROL MODULE DTC INSPECTION •  Switch the ignition off. •  Disconnect the negative battery cable and wait for 1 min or more. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION.) •  Connect the SAS control module connectors. •  Reconnect all disconnected connectors. •  Connect the negative battery cable. (See NEGATIVE BATTERY CABLE 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 (AIR BAG SYSTEM)].) •  Perform the DTC inspection for the SAS control module using the M-MDS. (See DTC INSPECTION [SAS CONTROL MODULE (AIR BAG SYSTEM)].) •  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.)
		No	DTC troubleshooting completed.
