DTC B1D75:62


id080200827900


System Malfunction Location

•  Passenger air bag deactivation (PAD) switch signal failure

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.
•  The SAS control module monitors the PAD switch status using the SAS control module terminals 3F and 3H voltages while the ignition switch is turned to the ON position. When the SAS control module detects that the compared terminal voltages values between SAS control module terminal 3F and 3H are the same, the SAS control module determines that the PAD switch related circuit is open or there is a short to GND

Possible Causes

•  Open or short to GND circuit in the wiring harness between SAS control module terminal 3F and PAD switch terminal C
•  Open or short to GND circuit in the wiring harness between SAS control module terminal 3H and PAD switch terminal D
•  Open circuit in the wiring harness between PAD switch terminal E and GND
•  PAD switch malfunction
•  SAS control module malfunction

Diagnostic Procedure

Step

Inspection

Action

1
INSPECT WHETHER MALFUNCTION IS SHORT TO GND CIRCUIT IN WIRING HARNESS BETWEEN SAS CONTROL MODULE AND PAD SWITCH
Warning
•  Handling the component parts improperly can accidentally operate (deploy) the air bag module, which may seriously injure you. Read the service warnings/cautions and the workshop manual before handling the air bag system components.
•  Switch the ignition to off.
•  Disconnect the negative battery cable and wait for 1 min or more.
•  Remove the column cover.
•  Disconnect the clock spring connector.
•  Remove the glove compartment cover.
•  Disconnect the passenger-side air bag module connector.
•  Disconnect the driver and passenger-side side air bag module connectors.
•  Disconnect the driver-side curtain air bag module connector.
•  Disconnect the driver and passenger-side pre-tensioner seat belt connectors.
•  Remove the rear console. (See REAR CONSOLE REMOVAL/INSTALLATION.)
•  Disconnect the SAS control module connectors.
•  Disconnect the PAD switch connector.
―  Terminal 3F (at harness-side connector)
―  Terminal 3H (at harness-side connector)
•  Is continuity detected?
Yes
Repair or replace the suspected wiring harness for the short to GND circuit.
No
Go to the next step.
2
INSPECT WHETHER MALFUNCTION IS OPEN CIRCUIT IN WIRING HARNESS BETWEEN SAS CONTROL MODULE AND PAD SWITCH OR ELSEWHERE
•  Disconnect the all SAS control module connectors.
•  Disconnect the PAD switch connector.
•  Verify that there is continuity between the SAS control module and the PAD switch for the following at the harness-side connector:
―  SAS control module terminal 3F—PAD switch terminal C
―  SAS control module terminal 3H—PAD switch terminal D
•  Is there continuity?
Yes
Go to the next step.
No
Repair or replace the suspected wiring harness for open circuit.
3
INSPECT WHETHER MALFUNCTION IS OPEN CIRCUIT IN WIRING HARNESS BETWEEN PAD SWITCH AND GND OR ELSEWHERE
•  Disconnect the all SAS control module connectors.
•  Disconnect the PAD switch connector.
•  Verify that there is continuity between PAD switch harness-side connector terminal E and GND.
•  Is there continuity?
Yes
Go to the next step.
No
Repair or replace the suspected wiring harness for an open circuit and inspect the GND point for poor contact.
4
INSPECT WHETHER MALFUNCTION SWITCH OR SAS CONTROL MODULE
•  Inspect the PAD switch.
•  Is the PAD switch normal?
Yes
Replace the SAS control module.
Then reconnect all disconnected connectors.
No
Then reconnect all disconnected connectors.


Passenger Air Bag Deactivation (PAD) Switch Inspection

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

2.  Remove the PAD switch.

3.  Verify that the continuity between the PAD switch terminals is as indicated in the table.
