Test L: DTC 1810 - Height Sensor Delta Out of Range
Test L: DTC 1810 - Height Sensor Delta Out of RangeNormal Operation
The 2 rear height sensors receive a 5-volt reference voltage from the air suspension module 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 air suspension module along circuit VCL12 (WH/VT). The LR sensor sends the suspension height voltage back to the module along circuit VCL13 (BN/BU). The air suspension module monitors the 2 height sensors and makes adjustments to the rear suspension based on sensor input.
Possible Causes
^ 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
