For a complete wiring diagram Refer to Section 8W.
•
When Monitored:
With the ignition on.
•
Set Condition:
1. If the Occupant Restraint Controller (ORC) senses a low resistance to battery voltage on the (G104) Pas-
senger Airbag Indicator Driver circuit. NOTE: Use the B1205-PASSENGER AIRBAG INDICATOR CIRCUIT
HIGH diagnostic test to repair the B1207-PASSENGER AIRBAG INDICATOR CIRCUIT SHORTED
TOGETHER trouble code. The Scan Tool will display both DTCs for a single problem.
Possible Causes
(G104) PASSENGER AIRBAG INDICATOR DRIVER CIRCUIT SHORTED TO (F23) FUSED IGNITION SWITCH
OUTPUT (RUN-START) CIRCUIT
(G104) PASSENGER AIRBAG INDICATOR DRIVER CIRCUIT SHORTED TO VOLTAGE
PASSENGER AIRBAG ON/OFF INDICATOR LAMP
ORC
Diagnostic Test
1.
VERIFY THAT DTC B1205 PASSENGER AIRBAG INDICATOR CIRCUIT HIGH IS ACTIVE
NOTE: Ensure the battery is fully charged.
NOTE: The scan tool, SRS Airbag Load Tool MRL 8443, and DVOM are required to perform the following
test.
NOTE: When reconnecting Airbag system components, the ignition must be turned off and the battery must
be disconnected.
Turn the ignition on.
With the scan tool, read ORC DTCs.
NOTE: B1207-PASSENGER AIRBAG INDICATOR CIRCUIT SHORTED TOGETHER

CHECK (G104) PASSENGER AIRBAG INDICATOR DRIVER CIRCUIT FOR A SHORT TO (F201) FUSED
IGNITION SWITCH OUTPUT (RUN-START) CIRCUIT
WARNING: If the Occupant Restraint Controller (ORC) is dropped
at any time, it must be replaced. Failure to take the proper pre-
cautions can result in accidental airbag deployment and personal
injury or death.
WARNING: If the Occupant Classification Module (OCM) is
dropped at any time, it must be replaced. Failure to take the
proper precautions can result in accidental airbag deployment
and personal injury or death.
WARNING: To avoid personal injury or death, turn the ignition off,
disconnect the battery and wait two minutes before proceeding.
Remove the Airbag Run-Start Fuse from the PDC.
Disconnect the ORC C1 and C2 connectors.
Disconnect the OCM C1 connector.
Disconnect the Switch Bank connector.
NOTE: Check connectors - Clean and repair as necessary.
Connect the appropriate Load Tool ORC Adaptor to the ORC connec-
tors.
Measure the resistance between the (G104) Passenger Airbag Indicator Driver circuit and the (F201) Fused Ignition
Switch Output (Run-Start) circuit in the Switch Bank connector.
Is the resistance below 100.0 ohms?
Yes
>> Repair the (G104) Passenger Airbag Indicator Driver circuit for a short to the (F201) Fused Ignition
Switch Output (Run-Start) circuit.
Perform ORC VERIFICATION TEST - VER 1.
No
>> Go To 3
3.
CHECK (G104) PASSENGER AIRBAG INDICATOR DRIVER CIRCUIT FOR A SHORT TO VOLTAGE
WARNING: To avoid personal injury or death, turn the ignition on,
then reconnect the battery.
Measure the voltage of the (G104) Passenger Airbag Indicator Driver
circuit.
Is there any voltage present?
Yes
>> Repair the (G104) Passenger Airbag Indicator Driver cir-
cuit for a short to voltage.
Perform ORC VERIFICATION TEST - VER 1.
No
