Park Enable Relay Control | B3631 00 | 1 | 2 | -- |
1. Adjustable Pedal Inhibit Inoperative 2. Adjustable Pedals Inoperative |
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.
• | The ignition is ON. |
• | The BCM attempts to energize the park enable relay. |
The BCM detects a short to ground on the park enable relay control circuit while attempting to activate the output.
The output will be disabled.
• | 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. |
Adjustable Pedals Description and Operation
Control Module References for scan tool information
Ignition ON, transmission in reverse, attempt to operate the adjustable pedals. The adjustable pedals should be disabled.
⇒ | 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. |
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
