B1D4E-11-ADJUSTABLE PEDAL INHIBIT - CIRCUIT SHORT TO GROUND





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

Theory of Operation

The Body Control Module (BCM) will disable the adjustable pedal function when the vehicle is in reverse or if the speed control is on. The BCM does this by providing voltage to the coil of the normally closed Adjustable Pedals Relay, which opens the contacts in the relay.

- When Monitored:
With the ignition on.

Vehicle is in reverse.

Speed control is active.

- Set Condition:
If the BCM detects a low voltage condition on the (P201) Adjustable Pedals Relay Driver circuit.





1. CHECK FOR ACTIVE DTC
1. Turn the ignition on, engine off.
2. With the scan tool, clear DTCs.
3. With the brakes firmly applied, shift the gear selector into REVERSE.
4. With the scan tool, read the active DTCs.

Does the scan tool display this DTC 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. CHECK THE ADJUSTABLE PEDALS RELAY FOR CORRECT OPERATION
1. Shift the gear selector into PARK.
2. Turn the ignition off.
3. Remove the Adjustable Pedals Relay and substitute it with a known good relay.
4. Turn the ignition on.
5. With the brakes firmly applied, shift the gear selector into REVERSE.
6. With the scan tool, read the active DTCs.

Does the scan tool display this DTC as active?

Yes

- Go To 3

No

- Replace the Adjustable Pedals Relay.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

3. CHECK THE (P201) ADJUSTABLE PEDALS RELAY DRIVER CIRCUIT FOR A SHORT TO GROUND
1. Turn the ignition off.
2. Remove the Adjustable Pedals Relay.
3. Disconnect the BCM E harness connector.
4. Measure the resistance between ground and the (P201) Adjustable Pedals Relay Driver circuit.

Is the resistance above 10k Ohms?

Yes

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

No

- Repair the short to ground in the (P201) Adjustable Pedals Relay Driver circuit.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
