5	FUSE INSPECTION •  Switch the ignition off. •  Disconnect the negative battery terminal and wait 1 min or more. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION.) •  Remove the SRS1 7.5 A fuse. •  Is the fuse normal?	Yes	Go to the next step.
		No	If the fuse is blown: •  Refer to the wiring diagram and verify whether or not there is a common connector between SRS1 7.5 A fuse and SAS control module 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. ―  Repair or replace the malfunctioning part. If there is no common connector: ―  Repair or replace the wiring harness which has a short to ground. •  Replace the fuse. If the fuse is damaged: •  Replace the fuse. Then go to Step 8.
6	INSPECT WIRING HARNESS BETWEEN SAS CONTROL MODULE AND IG1 RELAY No.1 Warning •  Handling the component parts improperly can accidentally operate (deploy) the air bag module, which may seriously injure you.

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 body ground. 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 the next step.
8	PERFORM SAS CONTROL MODULE DTC INSPECTION •  Connect the SAS control module connectors. •  Reconnect all disconnected connectors. •  Connect the negative battery terminal. (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 (STANDARD DEPLOYMENT CONTROL SYSTEM)].) •  Perform the DTC inspection for the SAS control module using the M-MDS. (See DTC INSPECTION [SAS CONTROL MODULE (STANDARD DEPLOYMENT CONTROL SYSTEM)].) •  Are the same Pending DTCs present?	Yes	Repeat the inspection from Step 1. •  If the malfunction recurs, replace the SAS control module. (See SAS CONTROL MODULE REMOVAL/INSTALLATION [STANDARD DEPLOYMENT CONTROL SYSTEM].)
