Signal Function

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2005 Ford RV Cutaway, 2005 Ford Pickup, 2005 Ford F550 Super Duty, 2005 Ford F450 Super Duty, and 2005 Ford Excursion. However, it is still accessible from the selected car via links, so may be relevant.

The BPP switch provides a 12-volt input signal to the powertrain control module (PCM) whenever the brake pedal is applied. The BPP switch input is used to deactivate the speed control system and the power take-off (PTO) system (if equipped).

CAUTION: The PCM harness connectors must be properly seated and the connector latch properly attached to eliminate possible driveability concerns or a no start condition. Installing the PCM connectors on an angle may cause an improper connection, misdiagnosis, and damaged components. Install the connector until the lever pivots and seats itself. Apply light pressure to get the connector into position on the PCM and then fully seat the connector.
NOTE: Visually inspect the harness connectors for corrosion, damage, proper mating, and correct pin tension.
