DTC Descriptor
DTC B3631 00: Adjustable Foot Pedal Inhibit CircuitDiagnostic Fault Information
Circuit | Short to Ground | Open/High Resistance | Short to Voltage | Signal Performance |
|---|---|---|---|---|
Park Enable Relay Control | B3631 00 | 1 | 2 | -- |
1. Adjustable Pedal Inhibit Inoperative 2. Adjustable Pedals Inoperative | ||||
Circuit/System Description
Voltage to the adjustable pedal switch is supplied through the park enable relay while in a de-energized state. The park enable relay is controlled by the body control module (BCM) through a high side drive control circuit and will be energized whenever the ignition is in the accessory, run, or crank positions and the transmission is in reverse or the cruise control is engaged.
Conditions for Running the DTC
| • | The ignition is ON. |
| • | The BCM attempts to energize the park enable relay. |
Conditions for Setting the DTC
The BCM detects a short to ground on the park enable relay control circuit while attempting to activate the output.
Action Taken When the DTC Sets
The output will be disabled.
Conditions for Clearing the DTC
| • | The DTC becomes history when the conditions for setting the DTC are no longer present. |
| • | The history DTC clears after 100 malfunction-free ignition cycles. |

Circuit/System Verification
Ignition ON, transmission in reverse, attempt to operate the adjustable pedals. The adjustable pedals should be disabled.
Circuit/System Testing
- Ignition OFF, disconnect the X2 harness connector at the left IP junction block.
- Ignition ON, transmission in reverse, verify that a test lamp illuminates between the control circuit terminal E3 and ground.
- If all circuits test normal, test or replace the left IP junction block.
| ⇒ | If the test lamp does not illuminate, test the control circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the BCM. |
Repair Instructions
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
