Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Dynamic Stability Control Sensor
1. DSC sensor
Located under the center console, the dynamic stability control sensor provides two inputs to the ABS ECU, lateral acceleration and rotational rate. The sensor is isolated from body/chassis vibrations through its rubber mounting.
For rotational speed, the sensor produces a reference signal of 2.5 volts and a linear voltage signal from 0.7 to 4.3 volts. This linear voltage input signal is used by the ABS ECU as the degree of rotational rate (yaw).
The sensor also produces a linear voltage signal for the lateral acceleration that ranges from 0.5 to 4.5 volts. The ABS ECU uses this input to determine the side forces acting on the vehicle for DSC regulation.
The DSC sensor has diagnostic capability via the ABS ECU through T4.
The DSC sensor also supplies the air suspension ECU cornering information.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
