Test B: DTC C1724 - Air Suspension Height Sensor Power Circuit Failure

Pinpoint Test B: DTC C1724 - Air Suspension Height Sensor Power Circuit Failure
Refer to Vehicle/Diagrams, Vehicle Dynamic Suspension for schematic and connector information.

Normal Operation
The air suspension module sends power to the height sensor along circuit 417 (VT/OG) and the voltage returns along circuit 432 (BK/PK). The sensor sends the position signal back to the air suspension module along circuit 427 (PK/BK).
^ DTC C1724 Air Suspension Height Sensor Power Circuit Failure - This DTC can be set during normal operation and during the air suspension module on-demand self test. DTC C1724 will set during normal operation if the ignition key is in the RUN position and the height sensor supply voltage is not at the expected level for more than 2 minutes. DTC C1724 will set during the on-demand self test if the height sensor voltage is not detected after being enabled during the test.

This pinpoint test is intended to diagnose the following:
^ Wiring, terminals or connectors
^ Air suspension height sensor
^ Air suspension module
