DETECTION CONDITION

WARNING:

• 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.

• Resistance other than 1.3—4.7 ohms detected in passenger-side side air bag module circuit

• Malfunction in wiring harness between passenger-side side air bag module and SAS control module

POSSIBLE CAUSE

• Open or short circuit in wiring harness between passenger-side side air bag module and SAS control module

• Passenger-side side air bag module malfunction

• SAS control module malfunction

STEP

INSPECTION

ACTION

1

• Using the M-MDS, verify the following PID/DATA monitor.

  (See PID/DATA MONITOR TABLE.)

• RES_SAB_P

• Is the resistance of the passenger-side side air bag module normal?

• Resistance: 1.3—4.7 ohms

Yes

Replace the SAS control module.

(See SAS CONTROL MODULE REMOVAL/INSTALLATION.)

No

Go to the next step.

2

WARNING:

• Handling the air bag system components improperly can accidentally deploy the air bag modules and pre-tensioner seat belts, which may seriously injure you. Read the air bag system service warnings and cautions before handling the air bag system components.

  (See AIR BAG SYSTEM SERVICE WARNINGS.)

  (See AIR BAG SYSTEM SERVICE CAUTIONS.)

• Turn the ignition switch to the LOCK position.

• Remove the battery cover.

• Disconnect the negative battery cable and wait for 1 min or more.

  (See BATTERY REMOVAL/INSTALLATION [LF].)

• Disconnect the passenger-side side air bag module connector.

• Is there any malfunction of the passenger-side side air bag module connector?

Yes

Replace the air bag wiring harness.

No

Go to the next step.

3

• Connect the leads of the SST (Fuel and thermometer checker) or apply 2-ohm resistance to passenger-side side air bag module connector terminals A and B.

• Set the resistance of the SST (Fuel and thermometer checker) to the 2-ohm position.

• Connect the negative battery cable.

• Turn the ignition switch to the ON position.

• Are DTCs B1055, B1996, B1997, B1998 and/or B1999 indicated?

Yes

Go to the next step.

No

Replace the passenger-side side air bag module.

(See SIDE AIR BAG MODULE REMOVAL/INSTALLATION.)

4

• Turn the ignition switch to the LOCK position.

• Remove the battery cover.

• Disconnect the negative battery cable and wait for 1 min or more.

  (See BATTERY REMOVAL/INSTALLATION [LF].)

• Remove the column cover.

• Disconnect the clock spring connector.

• Remove the glove compartment.

• Disconnect the passenger-side air bag module connector.

  (See PASSENGER-SIDE AIR BAG MODULE REMOVAL/INSTALLATION.)

• Disconnect the driver and passenger-side seat connectors.

• Remove the back trim.

• Disconnect the driver and passenger-side pre-tensioner seat belt connectors.

• Inspect the wiring harness between SAS control module terminal 2P and passenger-side side air bag module terminal A, SAS control module terminal 2S and passenger-side side air bag module terminal B for the following:

• Short to ground

• Short to power supply

• Open circuit

• Is the wiring harness normal?

Yes

Replace the SAS control module.

(See SAS CONTROL MODULE REMOVAL/INSTALLATION.)

No

Replace the air bag wiring harness.
