IPM-ORC #1 (F100 Circuit) Output Open
IPM-ORC #1 (F100 CIRCUIT) OUTPUT OPEN
For a complete wiring diagram Consult Diagrams/Electrical.
- When Monitored:
While the CAN bus ignition status received is RUN or signal not available, the module checks the (F100) ORC Run Driver circuit voltage.
- Set Condition:
If the Occupant Restraint Controller (ORC) detects battery voltage less than or equal to 6.50 ±0.25 volts on F100 circuit.
Diagnostic Test
1. CHECK FOR AN ACTIVE DTC
NOTE: Ensure the battery is fully charged.
NOTE: Troubleshoot any PCM charging/cranking DTCs before proceeding.
Turn the ignition on.
With the scan tool, read Occupant Restraint Controller (ORC) DTCs.
Does the scan tool display active: IPM-ORC #1 (F100 CIRCUIT) OUTPUT OPEN?
Yes
- Go To 2
No
- Go To 4
2. MEASURE THE VOLTAGE OF ORC (F100) ORC RUN DRIVER CIRCUIT
WARNING: To avoid serious or fatal injury, turn the ignition off, disconnect the battery and wait two minutes before proceeding.
Disconnect the ORC connectors.
Connect the Load Tool ORC 8443-24 Adapter to the ORC C2 connectors.
Using a 12 - volt test light connected to ground, check the (F100) ORC Run Driver circuit cavity 24 of the ORC 8443-24 Adapter.
WARNING: To avoid serious or fatal injury, turn the ignition on, then reconnect the battery.
Turn the ignition off, wait 90 seconds, then turn the ignition on.
Does the test light illuminate brightly?
Yes
WARNING: If the Occupant Restraint Controller 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.
- Replace the ORC.
- Perform *ORC VERIFICATION TEST - VER 1. Occupant Restraint Controller (ORC) Verification Test
No
- Go To 3
3. CHECKING THE IPM (F100) ORC RUN DRIVER CIRCUIT
WARNING: To avoid serious or fatal injury, turn the ignition off, disconnect the battery and wait two minutes before proceeding.
Gain access to the IPM C4 connector.
Using a 12 - volt test light connected to ground, back probe the (F100) ORC Runt Driver circuit IPM C9 connector cavity 1.
WARNING: To avoid serious or fatal injury, turn the ignition on, then reconnect the battery.
Turn the ignition off, wait 90 seconds, then turn the ignition on.
Does the test light illuminate brightly?
Yes
- Repair the open or high resistance in the (F100) ORC Run Driver circuit.
- Perform *ORC VERIFICATION TEST - VER 1. Occupant Restraint Controller (ORC) Verification Test
No
- Replace the IPM.
- Perform *ORC VERIFICATION TEST - VER 1. Occupant Restraint Controller (ORC) Verification Test
4. 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 DTC(s).
No
- No problem found Erase all codes before returning vehicle to customer.
