B1D4E-11
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 Adjustable Pedals Relay Driver circuit.
Diagnostic Test
1. CHECK FOR ACTIVE DTC
1. Turn the ignition on.
2. With the brakes firmly applied, shift the gear selector into REVERSE.
3. 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 (P201) ADJUSTABLE PEDALS RELAY DRIVER CIRCUIT FOR A SHORT TO GROUND
1. Turn the ignition off.
2. Disconnect the PDC C5 harness connector.
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
- Go To 3
No
- Repair the short to ground in the (P201) Adjustable Pedals Relay Driver circuit.
- Perform the BODY VERIFICATION TEST. Body Verification Test .
3. CHECK THE BCM FOR CORRECT OPERATION
1. Turn the ignition off.
2. Reconnect the BCM E harness connector.
3. Using a 12-volt test light connected to ground, check the (X4) Horn Relay Control circuit at the PDC C5 harness connector.
4. Turn the ignition on.
5. With the brakes firmly applied, shift the gear selector into REVERSE.
Does the test light illuminate?
Yes
- Replace the PDC.
- Perform the BODY VERIFICATION TEST. Body Verification Test .
No
- Replace the Body Control Module (BCM). Body Control Module - Removal.
- Perform the BODY VERIFICATION TEST. Body Verification Test .
