Test H: The Air Compressor Continuously Cycles With the Ignition Switch in the OFF Position and No DTC is SetNormal Operation
The air suspension module will command the air compressor ON or OFF when certain conditions are met. The air suspension module supplies voltage to the air suspension compressor relay through circuit CCL01 (WH/VT), which engages the relay and supplies fused battery voltage along circuit SBB39 (WH/RD) through the air compressor relay and then to the air compressor along circuit CCL08 (BN/BU). The air compressor is supplied a ground along circuit AGD123 (BK/GY) and the air compressor relay is supplied a ground along circuit GD 123 (BK/GY).
Possible Causes
^ Circuit shorted
^ Air compressor relay
^ Air suspension module
