Test F: DTCs C1790/C1795 - LR/RR Air Suspension Air Spring Solenoid Output Circuit Failure
Test F: DTCs C1790/C1795 - LR/RR Air Suspension Air Spring Solenoid Output Circuit FailureRefer to Vehicle/Diagrams, Vehicle Dynamic Suspension for schematic and connector information.
Normal Operation
The air suspension module controls the air spring solenoid by sending a voltage along circuit 1114 (BN/PK) for the LR solenoid and circuit 1115 (TN/WH) for the RR solenoid. This voltage engages the solenoid allowing air to either enter or leave the air spring. Ground for both solenoids is provided along circuit 57 (BK).
Possible Causes
^ Circuit open
^ Circuit shorted
^ Air spring solenoid
^ Air suspension module
