B1207
B1207-PASSENGER AIRBAG INDICATOR CIRCUIT SHORTED TOGETHER
For a complete wiring diagram Consult 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.
WARNING: To avoid serious or fatal injury when reconnecting Airbag system components, turn the ignition off, disconnect the battery and wait two minutes before proceeding.
Turn the ignition on.
With the scan tool, read Occupant Restraint Controller (ORC) DTCs.
Does the scan tool display active: B1207 PASSENGER AIRBAG INDICATOR CIRCUIT SHORTED TOGETHER?
Yes
- Go To 2
No
- Go To 5
2. CHECK (R104) 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 precautions can result in accidental airbag deployment and serious or fatal injury.
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 C1 and C2 connectors.
Disconnect the Passenger Airbag On/Off Indicator Lamp connector.
NOTE: Check connectors - Clean and repair as necessary.
Connect the appropriate Load Tool ORC Adaptor (8443-25) to the ORC connectors.
Measure the resistance between the (R104) Passenger Airbag Indicator Driver circuit and the (F201) Fused Ignition Switch Output (Run-Start) circuit in the Passenger Airbag On/Off Indicator Lamp connector.
Is the resistance below 100.0 ohms?
Yes
- Repair the (R104) Passenger Airbag Indicator Driver circuit for a short to the (F201) Fused Ignition Switch Output (Run-Start) circuit.
- Perform *AIRBAG SYSTEM VERIFICATION TEST - VER 1.Airbag System Verification Test
No
- Go To 3
3. CHECK (R104) 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 (R104) Passenger Airbag Indicator Driver circuit between ground and the Passenger Airbag On/Off Indicator Lamp connector cavity 3.
Is there any voltage present?
Yes
- Repair the (R104) Passenger Airbag Indicator Driver circuit for a short to voltage.
- Perform *AIRBAG SYSTEM VERIFICATION TEST - VER 1.Airbag System Verification Test
No
- Go To 4
4. CHECK FOR ACTIVE DTC B1207 PASSENGER AIRBAG INDICATOR CIRCUIT SHORTED TOGETHER WITH PASSENGER AIRBAG ON/OFF INDICATOR LAMP 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 C1 and C2 connectors.
Reconnect the Passenger Airbag On/Off Indicator Lamp connectors.
WARNING: To avoid serious or fatal injury, turn the ignition on, then reconnect the battery.
With the scan tool, erase ORC DTCs.
Turn the ignition off, wait 10 seconds, and then turn the ignition on.
With the scan tool, read ORC DTCs.
Does the scan tool display active: B1207 PASSENGER AIRBAG INDICATOR CIRCUIT SHORTED TOGETHER?
Yes
- Replace the ORC.
- Perform *AIRBAG SYSTEM VERIFICATION TEST - VER 1.Airbag System Verification Test
No
- Replace the Passenger Airbag On/Off Indicator Lamp.
- Perform *AIRBAG SYSTEM VERIFICATION TEST - VER 1.Airbag System Verification Test
5. TEST FOR INTERMITTENT CONDITION
With the scan tool, record and erase all DTCs 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 codes are related to the Driver Airbag circuits, rotate the steering wheel from stop to stop.
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 DTCs?
Yes
- Diagnose and repair the DTCs.
No
- No problem found at this time. Erase all codes before returning vehicle to customer.
