Passenger-side air bag module system

DETECTION CONDITION

Warning
• Detection conditions are for understanding DTC outline before performing inspection. Performing inspection with only detection conditions may cause injury due to operating error or damage the system. When performing inspection, always follow inspection procedure.
• Abnormal resistance (other than 1.63-2.71 W) detected in passenger-side air bag module circuit
• Short circuit in wiring harness related SAS unit terminal 2Y or 2AB

POSSIBLE CAUSE

• Passenger-side air bag module malfunction
• Malfunction of connector between passenger-side air bag module and SAS unit

• SAS unit malfunction

Diagnostic procedure

STEP

INSPECTION

ACTION

1
INSPECT SEPARATOR* OF PASSENGER-SIDE AIR BAG MODULE CONNECTOR
Warning
• Handling air bag system components improperly can accidentally deploy air bag modules and pre-tensioner seat belts, which may seriously injure you. Read AIR BAG SYSTEM SERVICE WARNINGS before handling air bag system components. See SERVICE WARNINGS.
• Turn ignition switch to LOCK position.
• Disconnect negative battery cable and wait for more than 1 minute.
• Remove glove compartment.
• Disconnect passenger-side air bag module connector.
• Is separator* of passenger-side air bag module connector okay?
 
*: Consists of two parts of female connector that separate short bar from terminal when connected to male connector.
Yes
Present malfunction diagnosis:
• Go to next step.
Past malfunction diagnosis:
• Go to Step 3.
No
Replace wiring harness.
2
VERIFY WHETHER MALFUNCTION IS IN PASSENGER-SIDE AIR BAG MODULE OR OTHER PARTS
• Connect leads of SST (Fuel And
Thermometer checker) or apply 2 W resistor to passenger-side air bag module connector terminals A and B.
• Set resistance of SST (Fuel And
Thermometer checker) to 2 W.
• Connect negative battery cable.
• Turn ignition switch to ON position.
• Is DTC 7 indicated?
Yes
Go to next step.
No
Replace passenger-side air bag module.

INSPECT WIRING HARNESS BETWEEN PASSENGER-SIDE AIR BAG MODULE AND SAS unit
• Turn ignition switch to LOCK position.
• Disconnect negative battery cable and wait for more than 1 minute.
• Remove clock spring.
• Disconnect driver and passenger-side side air bag module connectors. (Vehicles with side air bag)
• Remove B-pillar lower trims. (Vehicle with pre-tensioner seat belt.)
• Disconnect driver and passenger-side pre-tensioner seat belt connectors. (Vehicle with pre-tensioner seat belt)
• Turn up floor covering.
• Disconnect all SAS unit connectors.
• Inspect following wiring harness between SAS unit and passenger-side air bag module terminals (harness side) for short to ground, short to power supply, and open circuit:
- 2Y and A
- 2AB and B
• Are wiring harnesses okay?
Yes
Present malfunction diagnosis:
• Replace SAS unit.
Past malfunction diagnosis:
• Replace passenger-side air bag module.
No
Replace wiring harnesses.
