Make: International
Engine: MaxxForce DT (2010 & Newer)
PID: N/A
SPN: 521
FMI: 19
Description: Brake switch circuit fault
Troubleshooting:
The Accelerator Pedal Position (APP) Sensor reads the position of the accelerator pedal. The
Electronic Control Module compares signals from two separate sensors to determine pedal
position. When the pedal is pressed, resistance decreases and the change in voltage is
interpreted by the Electronic Control Module
Probable Causes:
1) Brake Pedal switch or circuit fault

Description: Engine stopped by IST
Troubleshooting:
The Idle Shutdown Timer (IST) allows the ECM to shutdown the engine during extended
engine idle times.

Description: Cruise Control Enable Switch not detected on J1939
Troubleshooting:
The Cruise Control System allows the operator to set, resume, accelerate, or coast at the
desired speed.
Probable causes:
1) Cruise Control switch or circuit fault
2) See BCM for troubleshooting switch

FMI: 2
Description: Brake switch or circuit fault
Troubleshooting:
The Brake Switch provides the Electronic Control Module (ECM) with the brake position.
Probable causes:
1) Brake and accelerator depressed at same time
2) Body controller false input
3) Brake On / Off (BOO) switch dislodged (always on)
4) BOO switch closed
5) Not able to use cruise control
