DRIVER SEAT BELT TENSIONER SQUIB CIRCUIT (CONTINUED)
When Monitored and Set Condition
•
When Monitored: Ignition on. The Occupant Restraint Controller (ORC) monitors the resistance of the Driver
Seat Belt Squib circuits.
•
Set Condition: The Occupant Restraint Controller (ORC) has detected abnormally high voltage, low resistance,
high resistance or an open circuit on one or both of the Driver Seat Belt Squib circuits.
POSSIBLE CAUSES
DRIVER SEAT BELT SQUIB CIRCUIT(S) OPEN
DRIVER SEAT BELT SQUIB CIRCUIT(S) SHORT TO VOLTAGE
DRIVER SEAT BELT SQUIB CIRCUIT(S) SHORT TO GROUND
DRIVER SEAT BELT SQUIB CIRCUITS SHORT TO EACH OTHER

Diagnostic Test
1.
WITH THE DRB III
T
, READ DTCs
Note: When reconnecting the Airbag System components, the
ignition must be turned off and the battery must be disconnected.
Note: Ensure the battery is fully charged.
Turn the ignition on.
With the DRB III
T
, select ACTIVE or STORED DTCs.
Is the DTC ACTIVE?
Yes
>> Go to 2
No
>> Go to 10

2.
WITH THE DRB III
T
, READ ACTIVE DTCs
WARNING: TURN THE IGNITION OFF, DISCONNECT THE BAT-
TERY AND WAIT TWO MINUTES BEFORE PROCEEDING.
Disconnect the Driver Seat Belt Tensioner connector.
Note: Check connectors - Clean/repair as necessary.
Connect the appropriate Load Tool to the Driver Seat Belt Tensioner
Squib connector.
WARNING: TURN THE IGNITION ON, THEN RECONNECT THE
BATTERY.
With the DRB III
T
, read the active DTCs.
Does the DRB III
T
display an active Driver Seat Belt Tensioner
Squib DTC?
Yes
>> Go to 3
No
>> Replace the Driver Seat Belt Tensioner. (Refer to 8 - ELECTRICAL/RESTRAINTS/SEAT BELT &
RETRACTOR - REMOVAL).
Perform AIRBAG VERIFICATION TEST. (Refer to 8 - ELECTRICAL/RESTRAINTS - DIAGNOSIS AND
TESTING).
3.
MEASURE THE RESISTANCE OF THE DRIVER SEAT BELT SQUIB LINE 1 CIRCUIT
WARNING: TURN THE IGNITION OFF, DISCONNECT THE BAT-
TERY AND WAIT TWO MINUTES BEFORE PROCEEDING.
Disconnect the ORC harness connector.
Note: Check connectors - Clean/repair as necessary.
Connect the appropriate harness adapter to the ORC connector.
Disconnect the Load Tool from the Driver Seat Belt Tensioner Squib
connector.
Measure the resistance of the Driver Seat Belt Squib Line 1 circuit
from the ORC connector to the Driver Seat Belt Tensioner Squib con-
nector.
Is the resistance below 1.0 ohm?
Yes
>> Go to 4
No
>> Repair the Driver Seat Belt Squib Line 1 circuit for an
open.
Perform AIRBAG VERIFICATION TEST. (Refer to 8 -
ELECTRICAL/RESTRAINTS - DIAGNOSIS AND TEST-
ING).
Note: When reconnecting the Airbag System components, the
ignition must be turned off and the battery must be disconnected.

4.
MEASURE THE RESISTANCE OF THE DRIVER SEAT BELT SQUIB LINE 2 CIRCUIT
With the ignition off.
Measure the resistance of the Driver Seat Belt Squib Line 2 circuit
from the ORC connector to the Driver Seat Belt Tensioner Squib con-
nector.
Is the resistance below 1.0 ohm?
Yes
>> Go to 5
No
>> Repair the Driver Seat Belt Squib Line 2 circuit for an
open.
Perform AIRBAG VERIFICATION TEST. (Refer to 8 -
ELECTRICAL/RESTRAINTS - DIAGNOSIS AND TEST-
ING).
Note: When reconnecting the Airbag System components, the
ignition must be turned off and the battery must be disconnected.
5.
MEASURE THE RESISTANCE OF THE DRIVER SEAT BELT SQUIB CIRCUITS
With the ignition off.
Measure the resistance between the Driver Seat Belt Squib Line 1 cir-
cuit and the Driver Seat Belt Squib Line 2 circuit at the Driver Seat
Belt Tensioner Squib connector.
Is the resistance below 10K ohms?
Yes
>> Repair the Driver Seat Belt Squib circuits for a short to
each other.
Perform AIRBAG VERIFICATION TEST. (Refer to 8 -
ELECTRICAL/RESTRAINTS - DIAGNOSIS AND TEST-
ING).
Note: When reconnecting the Airbag System components, the
ignition must be turned off and the battery must be disconnected.
No
>> Go to 6
6.
MEASURE THE VOLTAGE OF THE DRIVER SEAT BELT SQUIB LINE 1 CIRCUIT
WARNING: TURN THE IGNITION ON, THEN RECONNECT THE
BATTERY.
Measure the voltage of the Driver Seat Belt Squib Line 1 circuit at the
Squib connector.
Is voltage present?
Yes
>> Repair the Driver Seat Belt Squib Line 1 circuit for a short
to voltage.
Perform AIRBAG VERIFICATION TEST. (Refer to 8 -
ELECTRICAL/RESTRAINTS - DIAGNOSIS AND TEST-
ING).
Note: When reconnecting the Airbag System components, the
ignition must be turned off and the battery must be disconnected.
