Signal Function

WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2004 Ford RV Cutaway, 2004 Ford Pickup, 2004 Ford F550 Super Duty, 2004 Ford F450 Super Duty, and 2004 Ford Excursion. However, it is still accessible from the selected car via links, so may be relevant.

The parking brake switch provides an input signal to the powertrain control module (PCM) indicating the current status of the parking brake (applied or released). The parking brake signal circuit is pulled to ground with the application of the parking brake.

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.
NOTE: When the PCM is disconnected additional DTCs will be set. Clear all DTCs after restoring the vehicle.
