DTC 6

Driver-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 1.85-3.46 W) detected in driver-side air bag module circuit
• Short circuit in wiring harness related SAS unit terminal 2D or 2G

POSSIBLE CAUSE

• Driver-side air bag module malfunction
• Clock spring malfunction
• Malfunction of connectors between clock spring and SAS unit
• Open or short circuit in wiring harness between clock spring and SAS unit
• SAS unit malfunction

Diagnostic procedure

STEP

INSPECTION

ACTION

1
INSPECT SEPARATOR* OF CLOCK SPRING
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 driver-side air bag module. (Vehicle with side air bag)
• Is separator* of clock spring 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 6.
No
Replace clock spring.
2
VERIFY WHETHER MALFUNCTION IS IN DRIVER-SIDE AIR BAG MODULE OR OTHER PARTS
• Connect leads of SST (Fuel And Thermometer checker) or apply 2 W resistor to clock spring terminals 3A and 3B.
• Set resistance of SST (Fuel And Thermometer checker) to 2 W.
• Connect negative battery cable.
• Turn ignition switch to ON position.
• Is DTC 6 indicated?
Yes
Go to next step.
No
Replace driver-side air bag module.
3
INSPECT SEPARATOR* OF CLOCK SPRING CONNECTOR
• Turn ignition switch to LOCK position.
• Disconnect negative battery cable and wait for more than 1 minute.
• Remove clock spring.
• Is separator* of clock spring connector okay?
 
*: Consists of two parts of female connector that separate short bar from terminal when connected to male connector.
Yes
Go to next step.
No
Replace wiring harness.
4
VERIFY WHETHER MALFUNCTION IS IN CLOCK SPRING OR OTHER PARTS
• Connect leads of SST (Fuel And Thermometer checker) or apply 2 W resistor to clock spring 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 6 indicated?
Yes
Go to next step.
No
Replace clock spring.
5
INSPECT WIRING HARNESS BETWEEN CLOCK SPRING AND SAS unit
• 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.
• Disconnect driver and passenger-side side air bag module connectors. (Vehicle 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 clock spring terminals (harness side) for short to ground, short to power supply, and open circuit:
- 2D and A
- 2G and B
• Are wiring harnesses okay?
Yes
Replace SAS unit.
No
Replace wiring harnesses.
6
INSPECT SEPARATOR* OF CLOCK SPRING CONNECTOR
• Remove clock spring.
• Is separator* of clock spring connector okay?
 
*: Consists of two parts of female connector that separate short bar from terminal when connected to male connector.
Yes
Go to next step.
No
Replace wiring harness.
7
INSPECT CLOCK SPRING
• Remove clock spring.
• Inspect clock spring.
• Is clock spring okay?
Yes
Go to next step.
No
Replace clock spring.
8
INSPECT WIRING HARNESS BETWEEN CLOCK SPRING AND SAS unit
• Remove glove compartment.
• Disconnect passenger-side air bag module connector.
• 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 clock spring terminals (harness side) for short to ground, short to power supply, and open circuit:
- 2D and A
- 2G and B
• Are wiring harnesses okay?
Yes
Replace driver-side air bag module.
No
Replace wiring harnesses.
