voltage signal. The BCM sends a serial data message to the engine control module (ECM)/powertrain control module (PCM) indicating the status
of the stop lamps.
Conditions for Running the DTC
The engine is ON.
Conditions for Setting the DTC
* The ECM/PCM receives an invalid brake pedal status serial data message from the BCM.
* This diagnostic runs continuously.
Actions Taken When the DTC Sets
* The cruise control system becomes disabled.
* The malfunction indicator lamp (MIL) will not illuminate.
Conditions for Clearing the DTC
* The condition responsible for setting the DTC no longer exists.
* A history DTC will clear after 40 malfunction-free ignition cycles have occurred.

Circuit/System Verification
1. Verify that DTC P0572 or P0573 is not set.
瀚慖f DTC is set, refer to Diagnostic System Check - Vehicle (See: Testing and Inspection/Initial Inspection and Diagnostic
Overview/Diagnostic System Check - Vehicle).
2. Verify that DTC P0703 is not set.
瀚慖f DTC is set, replace the BCM. Clear the DTC and road test the vehicle. If DTC resets, replace the ECM/PCM.
Repair Instructions
Perform the Diagnostic Repair Verification (See: Verification Tests) after completing the diagnostic procedure.
