The engine control module (ECM) monitors brake switches and vehicle speed. The ECM will set a fault when it has detected the vehicle speed is above a threshold for a period of time and has stopped twice without brake activity and cycling of the key switch.

Component Location
Refer to the equipment manufacturer information location.

Conditions for Running the Diagnostics
This diagnostic runs continuously when the keyswitch is in the ON position or when the engine is running.

Conditions for Setting the Fault Codes
The ECM has detected the vehicle speed has been above 28 MPH for 5 minutes and has decreased to less than 2 MPH twice without brake activity.

Action Taken When the Fault Code is Active
-The ECM logs the fault code immediately when the diagnostic runs and fails..

Conditions for Clearing the Fault Code
-To validate the repair using a Diagnostic Road Test, utilize a route that incorporates both stop-and-go city-type driving and steady state highway type driving. It may be necessary to load the unit for certain diagnostics in the ECM to run.
-The fault code status displayed by INSITE™ electronic service tool will change to INACTIVE immediately after the diagnostic runs and passes.
-The Reset All Faults command in INSITE™ electronic service tool can be used to clear active and inactive faults, as well as extinguish the malfunction indicator lamp (MIL) for on-board diagnostics (OBD) applications.

Possible Causes
-A malfunctioning brake pedal position switch
-A malfunctioning Vehicle Speed Sensor
-A malfunctioning ECM.
