Test B: DTC C1724 - Air Suspension Height Sensor Power Circuit Failure
Test B: DTC C1724 - Air Suspension Height Sensor Power Circuit FailureRefer to Vehicle/Diagrams, Vehicle Dynamic Suspension for schematic and connector information.
Normal 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) and 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
^ Circuit open
^ Circuit shorted
^ Height sensor(s)
^ Air suspension module
