Test D: DTC C1770 - Air Suspension Vent Solenoid Output Circuit Failure
Test D: DTC C1770 - Air Suspension Vent Solenoid Output Circuit FailureRefer to Vehicle/Diagrams, Vehicle Dynamic Suspension for schematic and connector information.
Normal Operation
The air suspension module will command the air suspension system vent solenoid ON or OFF when certain conditions are met. The air suspension module supplies voltage to the vent solenoid through circuit CCL14 (BN/VT), which activates the vent solenoid and vents the air suspension system. The vent solenoid is grounded through circuit GD123 (BK/GY).
The vent solenoid is part of the air suspension compressor, if a new vent solenoid is needed, an air suspension compressor must be installed.
Possible Causes
^ Circuit open
^ Circuit shorted
^ Air suspension compressor
^ Air suspension module
