B215B-14-IGNITION RUN/START 2 CONTROL - CIRCUIT SHORT TO GROUND OR OPEN





For a complete wiring diagram, refer to the Wiring Information.

- When Monitored:
During a Passive Entry or Keyless Go event.

- Set Condition:
Whenever the Radio Frequency Hub (RF Hub) senses an open, or a short to ground on the F20 Ignition Run/Start Output circuit, this code will set.

- NOTE: This F20 circuit is a sense circuit from the Radio Frequency Hub to the Body Control Module. It has a maximum draw of 10mA.





1. TEST FOR INTERMITTENT CONDITION
1. Turn the ignition on.
2. Using the scan tool, record and erase the D's.
3. Try to start the engine.
4. With the scan tool, read the Active DTCs and wait one minute.

Does the scan tool display: B215B-14-IGNITION RUN/START 2 CONTROL - CIRCUIT SHORT TO GROUND OR OPEN as active?

Yes

- Go To 2

No

- Test complete, the condition or conditions that originally set this DTC are not present at this time. Using the wiring diagrams as a guide, check all related splices and connectors for signs of water intrusion, corrosion, pushed out or bent terminals and correct pin tension.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

2. (F20) IGNITION SWITCH OUTPUT CIRCUIT OPEN




1. Turn the ignition off.
2. Disconnect the Body Control Module E harness connector.
3. Turn the ignition on.
4. Measure the voltage between ground and the (F20) Ignition Switch Output circuit in the Body Control Module E connector.

Is the voltage above 11.5 Volts?

Yes

- Replace the Body Control Module. Body Control Module - Removal.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Go To 3

3. (F20) IGNITION SWITCH OUTPUT CIRCUIT SHORT TO GROUND




1. Turn the ignition off.
2. Disconnect the Radio Frequency Hub (RF Hub) C1 harness connector.
3. Measure the resistance between ground and the (F20) Ignition Switch Output circuit.

Is the resistance below 30K Ohms?

Yes

- Repair the short to ground in the (F20) Ignition Switch Output circuit.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Go To 4

4. (F20) IGNITION SWITCH OUTPUT CIRCUIT WIRE OPEN




1. Measure the resistance of the (F20) Ignition Switch Output wire between the Body Control Module E harness connector and the RF Hub C1 connector.

Is the resistance below 2.0 Ohms?

Yes

- Replace the Radio Frequency Hub (RF Hub) Module. Radio Frequency Module (RF Hub) - Removal.
- NOTE: If this vehicle is equipped with a Steering Wheel Lock Module (Export) it will have to be replaced also.

- Replace the Steering Wheel Lock Module. Shaft Lock Module - Removal
- Perform the RADIO FREQUENCY HUB VERIFICATION TEST. RF Hub Verification Test

No

- Repair the open in the (F20) Ignition Switch Output wire.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
