B1207
B1207-PASSENGER AIRBAG INDICATOR CIRCUIT SHORTED TOGETHER
For a complete wiring diagram refer to Diagrams/Electrical.
- When Monitored:
With the ignition on.
- Set Condition:
When the ORC detects over current on the Indicator Driver circuit.
Diagnostic Test
1. VERIFY THAT DTC B1207-PASSENGER AIRBAG INDICATOR CIRCUIT SHORTED TOGETHER IS ACTIVE
NOTE: Ensure the battery is fully charged.
Turn the ignition on.
With the scan tool, read Occupant Restraint Controller (ORC) DTC.
Does the scan tool display active: B1207-PASSENGER AIRBAG INDICATOR CIRCUIT SHORTED TOGETHER?
Yes
- Go To 2
No
- Go To 5
2. CHECK (G104) PASSENGER AIRBAG INDICATOR DRIVER CIRCUIT FOR A SHORT TO (F201) FUSED IGNITION SWITCH OUTPUT (RUN-START) CIRCUIT
WARNING: To avoid serious or fatal injury, turn the ignition off, disconnect the battery and wait two minutes before proceeding.
Remove the Passenger Airbag (PAB) Indicator Run-Start Fuse from the Junction Block.
Disconnect the ORC connectors.
WARNING: If the Occupant Restraint Controller (ORC) is dropped at any time, it must be replaced. Failure to take the proper precautions could result in accidental airbag deployment and serious or fatal injury.
Disconnect the Passenger Airbag On/Off Switch connector.
NOTE: Check connectors - Clean and repair as necessary.
Connect the appropriate Load Tool ORC 8443-25 Adaptor to the ORC connectors.
Measure the resistance between the (G104) Passenger Airbag Indicator Driver circuit and the (F201) Fused Ignition Switch Output (Run-Start) circuit in the Passenger Airbag On/Off Switch 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. Occupant Restraint Controller (ORC) Verification Test
No
- Go To 3
3. CHECK (G104) PASSENGER AIRBAG INDICATOR DRIVER CIRCUIT FOR A SHORT TO VOLTAGE
WARNING: To avoid serious or fatal injury, turn the ignition on, then reconnect the battery.
Measure the voltage of the (G104) Passenger Airbag Indicator Driver circuit between ground and the Passenger Airbag On/Off Switch Lamp connector cavity 3.
Is there any voltage present?
Yes
- Repair the (G104) Passenger Airbag Indicator Driver circuit for a short to voltage.
- Perform *ORC VERIFICATION TEST - VER 1. Occupant Restraint Controller (ORC) Verification Test
No
- Go To 4
4. CHECK FOR ACTIVE DTC B1207-PASSENGER AIRBAG INDICATOR CIRCUIT SHORTED TOGETHER WITH PASSENGER AIRBAG ON/OFF SWITCH DISCONNECTED
WARNING: To avoid serious or fatal injury, turn the ignition off, disconnect the battery and wait two minutes before proceeding.
Remove the Load Tool ORC Adaptor from the ORC connectors.
Reconnect the ORC connectors.
WARNING: To avoid serious or fatal injury, turn the ignition on, then reconnect the battery.
Turn the ignition off, wait 10 seconds, and then turn the ignition on.
With the scan tool, read ORC DTC.
Does the scan tool display active: B1207-PASSENGER AIRBAG INDICATOR CIRCUIT SHORTED TOGETHER?
Yes
- Replace the ORC.
- Perform *ORC VERIFICATION TEST - VER 1. Occupant Restraint Controller (ORC) Verification Test
No
- Replace the Passenger Airbag On/Off Switch.
- Perform *ORC VERIFICATION TEST - VER 1. Occupant Restraint Controller (ORC) Verification Test
5. TEST FOR INTERMITTENT CONDITION
With the scan tool, record and erase all DTC from all Airbag modules.
If any ACTIVE codes are present they must be resolved before diagnosing any stored codes.
WARNING: To avoid serious or fatal injury, turn the ignition off, disconnect the battery and wait two minutes before proceeding.
Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.
Look for chafed, pierced, pinched, or partially broken wires and broken, bent, pushed out, spread, corroded, or contaminated terminals.
The following additional checks may assist you in identifying a possible intermittent problem.
Reconnect any disconnected components and harness connector.
WARNING: To avoid serious or fatal injury, turn the ignition on, then reconnect the battery.
With the scan tool, monitor active codes as you work through the following steps.
WARNING: To avoid serious or fatal injury, maintain a safe distance from all airbags while performing the following steps.
Wiggle the wiring harness and connectors of the related airbag circuit or component.
If only stored codes return, continue the test until the problem area has been isolated.
In the previous steps you have attempted to recreate the conditions responsible for setting the active DTC in question.
Does the scan tool display any ACTIVE DTC?
Yes
- Select appropriate symptom from Symptom List.
No
- No problem found at this time. Erase all codes before returning vehicle to customer.
