Diagnosis and repair



NOTE: For more information on the pneumatic system components, proceed to the Air Suspension Pneumatic Diagram.

1.Connect NGS Tester to the data link connector C228F.
2.Select the proper vehicle year, model, and engine type.
3.Select the "Active Command Modes" menu "Air Suspension Control " for the 4WAS-AIR SUSP/EVO (4x2 and 4x4) module.
4.Monitor the PID FHGTSEN.
5.Use the active command "LIFT FRNT" to lift the front noticeably higher (should only take about 30 seconds).

NOTE: If vehicle does not raise at all, inspect for kinks or excessive leaks in all front air lines and all connectors.

6.Wait a few seconds for the front air suspension height sensor voltage reading to stabilize. If the front air suspension height sensor voltage reading does not stabilize (voltage value increases), check for leaks and kinks in the air line between the air suspension LF air shock and the air suspension gate solenoid. Check the air lines for incorrect connection(s) at the air suspension LF air shock and air suspension gate solenoid. Check air suspension LF air shock for failure. Repair and/or replace as necessary. If fault is not found, check for leaks and kinks in the air line between the air suspension RF air shock, air suspension gate solenoid, air suspension front fill solenoid, and the T-fitting. Check the air lines for incorrect connection(s) at the air suspension RF air shock, air suspension gate solenoid, air suspension front fill solenoid and the T-fitting. Check air suspension RF shock for failure. Repair and/or replace as necessary.

7.Open the air suspension gate solenoid with the active command "GATEVALVE".
8.Wait a few seconds for the front air suspension height sensor voltage reading to stabilize. If the front air suspension height sensor voltage reading does not stabilize (voltage value increases), check for leaks and kinks in the air line between the air suspension, RF and LF air shocks, air suspension gate solenoid, air suspension front fill solenoid, and the T-fitting. Check the air lines for incorrect connection(s) at the air suspension RF and LF air shocks, air suspension gate solenoid, air suspension front fill solenoid and the T-fitting. Repair and/or replace as necessary.
9.Open the air suspension front fill solenoid with the active command "FRNT FILL". Leave the air suspension gate solenoid open.
10.Wait a few seconds for the front air suspension height sensor voltage reading to stabilize. If the front air suspension height sensor voltage reading does not stabilize (voltage value increases), check for leaks and kinks in the air line between the air suspension front fill solenoid and the air suspension air drier, and between the air suspension air drier and the air suspension rear fill solenoid. Check the air lines for incorrect connection(s) at the air suspension front fill solenoid, air suspension air drier, air suspension rear fill solenoid and the union connector. Check the O-ring seal of the air suspension air drier to the air compressor assembly. Repair and/or replace as necessary. If the fault can not be found, replace the air compressor assembly.
11.Close all air suspension solenoids.
12.If the Air Leak Test-Rear has not been performed, perform the Air Leak Test-Rear.
