Electronic Stability Program: Notes

2009 Jeep Compass Limited, EDG, Automatic CVTSECTION Notes

Electronic Stability Program (ESP®), which includes Hydraulic Brake Assist, Traction Control, Electronic Roll Mitigation, and Brake Lock Differentials is standard on all vehicles. ESP® aids the driver in maintaining vehicle directional stability. ESP will do whatever can be done, within the limits of available traction, to keep the car on course.

ESP® uses the ABS with Traction Control (MK25E) along with the following components to operate:

  • Dynamics (ESP) Sensor
  • Steering Angle Sensor (SAS)

The Dynamics Sensor that is mounted under the center console, which is near the center of gravity of the car for effective sensing. See Brakes/Electrical/SENSOR, Dynamics - Description . The Steering Angle Sensor is located in the steering column. See Brakes/Electrical/SENSOR, Steering Wheel Angle - Description .

On this vehicle, ESP® has three modes: Full-On, Partial and Full-Off. The ESP® default mode is Full-On with every key-on. Pressing the ESP Off switch button in the center stack once activates the Partial mode. In Partial mode, Traction Control is deactivated and ESP® operates at a higher threshold, therefore, it will not come on as aggressively as in the Full-On mode. Pressing and holding the ESP Off switch button for five seconds or longer turns the system completely off. This condition is confirmed by a single warning chime and a text message in the odometer display "ESP FULL OFF." The system can be returned to "normal" Full-On mode by briefly pressing and releasing the ESP Off switch.
