C1810 Description

 

The 2 rear height sensors receive a 5-volt reference voltage from the Vehicle Dynamics Module (VDM), both sensors share a common return path. The RR sensor sends the suspension height voltage back to the VDM. The LR sensor sends the suspension height voltage back to the module. The VDM monitors the 2 height sensors and makes adjustments to the rear suspension based on sensor input. The ECM sets the OBDII code when the Air Suspension Height Sensor is not to factory specifications.
