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 BPA switch provides a backup signal for the brake pedal position (BPP) switch. If the BPP switch signal is lost, the BPA switch provides the brakes-applied signal to deactivate the speed control system.

CAUTION: The powertrain control module (PCM) harness connectors must be properly seated and the connector latch properly attached to eliminate possible driveability concerns or a no-start condition. Installing 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.
