•  Detection conditions are for understanding the DTC outline before performing an inspection. Performing an inspection according to only the detection conditions may cause injury due to an operating error, or damage the system. When performing an inspection, always follow the inspection procedure.

Possible Cause

Diagnostic Procedure

STEP	INSPECTION		ACTION
1	Turn the ignition switch to the LOCK position. Connect the M-MDS. Turn the ignition switch to the ON position. Using the M-MDS, verify the DTCs and record the past malfunction DTCs. Is the present malfunction DTC B1932 displayed?	Yes	Note •  Indicates a hard malfunction. The malfunction is still present. This malfunction cannot be cleared until it is corrected and the DTC is no longer displayed. Go to the next step.
		No	Intermittent malfunction. The malfunction is not present at this time. Go to the next step.
2	Warning •  Handling the components improperly can accidentally deploy the air bags and pre-tensioner front buckle, which may seriously injure you. Read the service warnings and cautions before handling the SRS air bag system components. (See AIR BAG SYSTEM SERVICE WARNINGS.) (See AIR BAG SYSTEM SERVICE CAUTIONS.) Turn the ignition switch to the LOCK position. Refer to the air bag system deactivation procedure and deactivate the system. Turn the ignition switch to the ON position. Perform the DTC inspection. Is the present malfunction DTC B1932 displayed?	Yes	Go to the next step.
		No	Replace the driver-side air bag module. (See DRIVER-SIDE AIR BAG MODULE REMOVAL/INSTALLATION.) After replacement, go to Step 6.
3	Turn the ignition switch to the LOCK position. Disconnect the negative battery cable. Disconnect SAS control module connector. Disconnect the SST (diagnostic simulator) from clock spring driver-side air bag module-side connector. Measure the resistance between clock spring driver-side air bag module-side connector terminal A and B. Note •  Measure the resistance while shaking the wiring harness between the SAS control module and clock spring. Is the resistance more than 1.4 ohms?	Yes	Go to the next step.
		No	Replace the SAS control module. (See SAS CONTROL MODULE REMOVAL/INSTALLATION.) After replacement, go to Step 6.
4	Disconnect the clock spring connector. Measure the resistance between clock spring terminal C and D. Note •  Inspect the clock spring wiring harness for continuity while shaking it. Is the resistance more than 0.5 ohms?	Yes	Repair the related wiring harness. After repair, go to Step 6.
		No	Replace the clock spring. (See CLOCK SPRING REMOVAL/INSTALLATION.) After replacement, go to Step 6.
5	Refer to the past malfunction DTCs recorded during Step 1. Are the past malfunction DTCs displayed during Step 1 intermittent malfunctions which are not displayed as present malfunction DTCs?	Yes	Inspect for the cause of intermittent high resistance between the driver-side air bag module and the SAS control module, and clock spring. Attempt to replicate the malfunction by flexing the wiring harness and cycling the ignition key between the ON and LOCK position repeatedly. Repair or replace if there is any intermittent malfunction. After repair or replacement. go to the next step.
		No	Go to the next step.
6	Refer to the past malfunction DTCs recorded during Step 1. Was any past malfunction DTC displayed during Step 1?	Yes	If any DTC is displayed, refer to the DTC table, and repair the malfunctioning part according to the DTC inspection.
		No	Refer to the reactivation procedure in the air bag system deactivation procedure, reactivate the system. Clear all DTCs.
