passenger air bag deactivation (PAD) indicator light does not illuminate

DETECTION CONDITION

Malfunction in passenger air bag deactivation (PAD) indicator light circuit (open circuit or short to power supply)

POSSIBLE CAUSE

• SAS control module malfunction
• passenger air bag deactivation (PAD) indicator light bulb malfunction
• Open or short to power supply circuit in wiring harness between passenger air bag deactivation (PAD) indicator light and SAS control module
• Poor contact at terminals 1U 1X and/or 1W of SAS control module connector
• Poor contact in wiring harness between terminal 1X of SAS control module connector and ground
• Poor contact or short circuits in wiring harness between METER IG 15 A fuse and SAS control module, between AIR BAG 15 A fuse and SAS control module at the time

Diagnostic Procedure

• When performing an asterisked (*) troubleshooting inspection, shake the wiring harness and connectors while doing the inspection to discover whether poor contact points are the cause of any intermittent malfunction. If there is a problem, check to make sure connectors, terminals and wiring harness are connected correctly and undamaged.

STEP

INSPECTION

ACTION

1
INSPECT PASSENGER AIR BAG DEACTIVATION (PAD) INDICATOR LIGHT BULB
• Disconnect the negative battery cable.
• Remove the center panel module.
• Is passenger air bag deactivation (PAD) indicator light bulb functional?
Yes
Reinstall it properly, then go to the next step.
No
Replace bulb, then go to Step 5.
*2
INSPECT WIRING HARNESS BETWEEN PASSENGER AIR BAG DEACTIVATION (PAD) INDICATOR LIGHT AND SAS CONTROL MODULE FOR CONTINUITY
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 service warnings and cautions before handling the air bag system components.
(See SERVICE WARNINGS.)
(See SERVICE CAUTIONS.)

• Remove the B-pillar lower trims. (Vehicle with pre-tensioner seat belt)
• Disconnect the driver- and passenger-side pre-tensioner seat belt connectors. (Vehicle with pre-tensioner seat belt)
• Turn up floor covering.
• Disconnect the all SAS control module connectors.
• Is there continuity between terminal 1U of SAS control module connector and terminal A of passenger air bag deactivation (PAD) indicator light?
Yes
Go to the next step.
No
Replace wiring harness, then go to Step 5.
*3
INSPECT WIRING HARNESS BETWEEN PASSENGER AIR BAG DEACTIVATION (PAD) INDICATOR LIGHT AND SAS CONTROL MODULE FOR SHORT TO POWER SUPPLY
• Connect the negative battery cable.
• Turn ignition switch to ON position.
• Measure voltage at terminal A of passenger air bag deactivation (PAD) indicator light connector.
• Is voltage approx. 9 V or more?
Yes
Replace wiring harness, then go to Step 5.
No
Go to the next step.
4
CHECK TO SEE WHETHER MALFUNCTION IS IN PASSENGER AIR BAG DEACTIVATION (PAD) INDICATOR LIGHT OR SAS CONTROL MODULE
• Connect the SAS control module connector terminal 1U to ground.
• Does passenger air bag deactivation (PAD) indicator light illuminate with ignition switch on?
Yes
Replace SAS control module, then go to the next step.
No
Go to the next step.
5
CONFIRM THAT MALFUNCTION SYMPTOMS DO NOT RECUR AFTER REPAIR
• Turn ignition switch to LOCK position.
• Disconnect the negative battery cable and wait for 1 min or more.
• Connect the all SAS control module connectors.
• Connect the driver and passenger-side pre-tensioner seat belt connectors. (Vehicles with pre-tensioner seat belt)
• Connect the driver and passenger-side curtain air bag module connectors. (Vehicles with curtain air bag)
• Connect the driver and passenger-side side air bag module connectors. (Vehicles with side air bag)
• Connect the passenger-side air bag module connector.
• Connect the clock spring connector.
• Connect the negative battery cable.
• Turn ignition switch to ON position.
• Does passenger air bag deactivation (PAD) indicator light operate properly?
