DTC 002
DTC 002
Circuit Description
The air suspension compressor assembly sends a pulse width modulation (PWM) voltage to the left height sensor at 25 ms intervals on the air suspension sensor signal circuit. The air suspension compressor assembly then measures the return voltage on the air suspension sensor low reference circuit and determines the vehicle height.
DTC Descriptor
This diagnostic procedure supports the following DTC:
DTC 002 Left Rear Position Sensor Circuit
Conditions for Running the DTC
The ignition is ON.
Conditions for Setting the DTC
The air suspension compressor assembly detects a invalid height sensor signal.
Action Taken When the DTC Sets
The air suspension compressor assembly shall disregard the left air suspension sensor input and use the right air suspension sensor to determine the vehicle height.
If both air suspension sensor DTCs are set, the air suspension compressor assembly shall deactivate the compressor, corner solenoids and exhaust solenoids. All leveling functions will be disabled. Inflator functions will not be disabled.
Conditions for Clearing the DTC
The DTC will automatically clear when the condition for setting the DTC is removed.
Diagnostic Aids
Resistance of the air suspension sensor at room temperature and normal vehicle height is approximately 87 ohms. The resistance range of the sensor is 75 - 100 ohms
