3

Passenger air bag deactivation (PAD) indicator light dose not illuminate

DETECTION CONDITION

Malfunction in PAD indicator light circuit (open circuit or short to power supply)

POSSIBLE CAUSE
•  SAS control module malfunction
•  PAD indicator light bulb malfunction
•  Open or short to power supply circuit in wiring harness between PAD indicator light and SAS control module
•  poor contact at terminals 1D and/or 2AB of SAS control module connector
•  poor contact in wiring harness between terminal 1D of SAS control module connector and ground
•  poor contact or short circuits in wiring harness between METER IG 15A fuse and SAS control module, between AIR BAG 15A 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 DTCS IN SAS CONTROL MODULE
•  Inspect the DTC for the SAS ON-BOARD DIAGNOSTIC SYSTEM.
•  Have DTCs B1844 and/or B1890 been recorded in memory?
Yes
Perform the applicable DTC inspection, then go to step6.
(See DTC TABLE.)
No
Go to the next step.
2
INSPECT PAD INDICATOR LIGHT BULB
•  Disconnect the negative battery cable.
•  Remove the center panel unit.
•  Is PAD indicator light bulb functional?
Yes
Reinstall it properly, then go to the next step.
No
Replace bulb, then go to step 6.
*3
INSPECT WIRING HARNESS BETWEEN 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.
•  Turn the ignition switch to LOCK position.
•  Disconnect the negative battery cable and wait for 1min or more.
•  Remove the column cover.
•  Disconnect the clock spring connector.
•  Remove the glove compartment.
•  Disconnect the passenger-side air bag module connector.
•  Disconnect the front seat connectors. (Vehicles with side air bag)
•  Disconnect the driver and passenger-side curtain air bag module connectors. (Vehicles with curtain air bag)
•  Remove the B-pillar lower trims.
•  Disconnect the driver and passenger-side pre-tensioner seat belt connectors.
•  Turn up floor covering.
•  Disconnect the all SAS control module connectors.
•  Is there continuity between terminal 1G of SAS control module connector and terminal A of PAD indicator light?
Yes
Go to the next step.
No
Replace wiring harness, then go to step 6.
*4
INSPECT WIRING HARNESS BETWEEN 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 PAD indicator light connector.
•  Is voltage approx. 9V or more?
Yes
Replace wiring harness, then go to step 6.
No
Go to the next step.
5
CHECK TO SEE WHETHER MALFUNCTION IS IN PAD INDICATOR LIGHT OR SAS CONTROL MODULE
•  connect the SAS control module connector terminal 1G to ground.
•  Does 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.
6
CONFIRM THAT MALFUNCTION SYMPTOMS DO NOT RECUR AFTER REPAIR
•  Turn ignition switch to LOCK position.
•  Disconnect the negative battery cable and wait for 1min or more.
•  Connect the all SAS control module connectors.
•  Connect the driver and passenger-side pre-tensioner seat belt connectors.
•  Connect the driver and passenger-side curtain air bag module connectors. (Vehicles with curtain air bag)
•  Connect the front seat 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
•  Dose PAD indicator light operate properly?
Yes
Complete troubleshooting, then explain repairs to customer.
No
Recheck malfunction symptoms, then repeat from Step 1 if malfunction recurs.
