Diagnostic Procedure

Step	Inspection		Action
1	INSPECT PAD SWITCH CONNECTOR Warning •  Handling the component parts improperly can accidentally operate (deploy) the air bag module, 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.) •  Switch the ignition to off. •  Disconnect the negative battery cable and wait for 1 min or more. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5].)(See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5 (WITHOUT i-stop)].)(See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-D 2.2].) •  Remove the passenger-side lower panel. (See LOWER PANEL REMOVAL/INSTALLATION.) •  Disconnect the PAD switch connector. (See PASSENGER AIR BAG DEACTIVATION (PAD) SWITCH REMOVAL/INSTALLATION.) •  Inspect the PAD switch connector. (Corrosion, damage, and disconnected pins) •  Is there any malfunction of the PAD switch connector?	Yes	Replace the malfunctioning part, then go to Step 5.
		No	Go to the next step.
2	INSPECT PAD SWITCH 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 glove compartment. (See GLOVE COMPARTMENT REMOVAL/INSTALLATION.) •  Disconnect the passenger-side air bag module connector. (See PASSENGER-SIDE AIR BAG MODULE REMOVAL/INSTALLATION.) •  Disconnect the driver and passenger-side front seat connector. (See FRONT SEAT REMOVAL/INSTALLATION.) •  Remove the headliner. (See HEADLINER REMOVAL/INSTALLATION.) •  Disconnect the driver and passenger-side curtain air bag module connector. (See CURTAIN AIR BAG MODULE REMOVAL/INSTALLATION.) •  Remove the B-pillar lower trim. (See B-PILLAR LOWER TRIM REMOVAL/INSTALLATION.) •  Disconnect the driver and passenger-side pre-tensioner seat belt connector. (See FRONT SEAT BELT REMOVAL/INSTALLATION.) •  Remove the rear console. (See REAR CONSOLE 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 3N ―  SAS control module terminal 3K Note •  Inspect for continuity while shaking the wiring harness between the SAS control module and PAD switch. •  Is there continuity?	Yes	If there is a common connector:If there is no common connector: Refer to the wiring diagram and verify whether or not there is a common connector between SAS control module terminal and PAD switch terminal. •  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. •  Replace the wiring harness which has a short to ground. Go to Step 5.
		No	Go to the next step.
3	INSPECT PAD SWITCH CIRCUIT FOR OPEN CIRCUIT •  PAD switch and SAS control module connectors are disconnected. •  Inspect for continuity between the following terminals (wiring harness-side): ―  PAD switch terminal D—SAS control module terminal 3N ―  PAD switch terminal C—SAS control module terminal 3K Note •  Inspect for continuity while shaking the wiring harness between the SAS control module and PAD switch. •  Is there continuity?	Yes	Go to the next step.
		No	If there is a common connector:If there is no common connector: Refer to the wiring diagram and verify whether or not there is a common connector between SAS control module terminal and PAD switch terminal. •  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. •  Replace the wiring harness which has an open circuit. Go to Step 5.
4	INSPECT PAD SWITCH CIRCUIT FOR SHORT TO POWER SUPPLY •  PAD switch and SAS control module connectors are disconnected. •  Connect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5].)(See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5 (WITHOUT i-stop)].)(See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-D 2.2].) •  Switch the ignition ON (engine off or on). •  Measure the voltage at the following terminals (wiring harness-side): ―  SAS control module terminal 3N ―  SAS control module terminal 3K Note •  Measure the voltage while shaking the wiring harness between the SAS control module and PAD switch. •  Is the voltage 0 V?	Yes	Replace the PAD switch, then go to the next step. (See PASSENGER AIR BAG DEACTIVATION (PAD) SWITCH REMOVAL/INSTALLATION.)
		No	If there is a common connector:If there is no common connector: Refer to the wiring diagram and verify whether or not there is a common connector between SAS control module terminal and PAD switch terminal. •  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. •  Replace the wiring harness which has a short to power supply. Go to the next step.
5	PERFORM SAS CONTROL MODULE DTC INSPECTION •  Switch the ignition to off. •  Disconnect the negative battery cable and wait for 1min or more. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5].)(See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5 (WITHOUT i-stop)].)(See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-D 2.2].) •  Connect the SAS control module connectors. •  Reconnect all disconnected connectors. •  Connect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5].)(See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5 (WITHOUT i-stop)].)(See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-D 2.2].) •  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].) •  Perform the DTC inspection for the SAS control module using the M-MDS. (See DTC INSPECTION [SAS CONTROL MODULE].) •  Are the same DTCs present?	Yes	Replace the SAS control module. (See SAS CONTROL MODULE REMOVAL/INSTALLATION.)
		No	DTC troubleshooting completed.
