ID25 Air Line Check (Slow Inflation)

^ In order to determine why the left rear corner of the vehicle is inflating very slowly or not at all the following actions are required:

^ Disconnect left rear air line from left rear air spring solenoid valve.

^ Disconnect left rear air spring solenoid valve electrical connector so that the solenoid valve is not connected to vehicle wiring harness.

^ Release STAR test button so that the solenoid valve is not connected to vehicle wiring harness.

^ Release STAR test button so that it remains in the up HOLD position after code 28 has been displayed for at least 5 seconds.

NOTE: As long as STAR test button remains in the up HOLD position the air compressor assembly will continue to pump air through the air line.

^ Air is coming out of the air line:

Very slowly or none at all -- GO to ID26.

At a normal rate -- GO to ID27.
