SENSOR-DYNAMICS (ESP)
DESCRIPTION
The Yaw Rate and Lateral Acceleration Sensors are housed into one unit known as the Dynamics Sensor (1). The sensor is used to measure side-to-side (Lateral) motion and vehicle rotational sensing (how fast the vehicle is turning - Yaw).
Yaw and Lateral Acceleration Sensors cannot be serviced separately. The entire Dynamics Sensor must be replaced when necessary.
REMOVAL
1. Disconnect and isolate the battery negative cable from the battery post.
2. Remove the shifter housing center console. (Refer to 23 - BODY/INTERIOR/CENTER CONSOLE - REMOVAL)
3. Disconnect the wiring harness connector (3) at the dynamics sensor (1).
4. Remove the nuts (2) mounting the dynamics sensor to the floor pan tunnel (4).
5. Remove the dynamics sensor (1).
INSTALLATION
1. Install the dynamics sensor (1) over the studs mounted to the floor pan tunnel (4).
2. Install the two mounting nuts (2). Tighten the nuts to 9 N·m (80 in. lbs.).
3. Connect the wiring harness connector (3) to the dynamics sensor (1).
4. Install the shifter housing center console. (Refer to 23 - BODY/INTERIOR/CENTER CONSOLE - INSTALLATION)
5. Connect the battery negative cable to the battery post. It is important that this be performed properly. (Refer to 8 - ELECTRICAL/BATTERY SYSTEM - STANDARD PROCEDURE)
6. Perform the Verification Test and clear any faults. (Refer to 5 - BRAKES - STANDARD PROCEDURE)
