Test L: DTC 1810 - Air Suspension Height Sensor Delta Out of Range
Pinpoint Test L: DTC 1810 - Air Suspension Height Sensor Delta Out of RangeNormal Operation
The 2 rear height sensors receive a 5-volt reference voltage from the vehicle dynamics module (VDM) along circuit LCL12 (VT/OG), both sensors share a common return path along circuit RCL12 (GN/WH). The RR sensor sends the suspension height voltage back to the VDM along circuit VCL12 (WH/VT). The LR sensor sends the suspension height voltage back to the module along circuit VCL13 (BN/BU). The VDM monitors the 2 height sensors and makes adjustments to the rear suspension based on sensor input.
^ DTC C1810 Air Suspension Height Sensor Delta Out Of Range - When performing a self-test, a ride height adjustment or when the VDM adjusts the ride height through normal operation, if the left and right calculated ride height value differs by 100 mm (3.93 inch) or more, DTC C1810 will be set.
This pinpoint test is intended to diagnose the following:
^ Vehicle lean (air spring leak, asymmetric loading)
^ Height sensor bracket bent or loose
^ Height sensor link arm bent, loose or disconnected
^ Height sensor(s) out of calibration
^ Air tube restriction
