Code C0630 Description

The Suspension Control Module supplies a 5 V reference signal to each Suspension Position Sensor. The Suspension Position Sensors supply a signal of 0.35–4.75 V to the Suspension Control Module which represents the position between the body and the wheel. The sensors are also grounded through the Suspension Control Module. The Diagnostic Trouble Code (DTC) will be set when the Suspension Control Module measures a Suspension Position Sensor signal less than 0.35 V or greater than 4.75 V for more than 5 s while the vehicle is operated under normal driving conditions.
