A Hummer H2 actually, Trouble with air Suspension. Replace

Customer Question

A Hummer H2 actually, Trouble with air Suspension. Replace the right air spring but now won't lift. Disconnected the pump for a week waiting for the part. Pump work to inflate tires. When I start the car and close the door the pump runs for Exactly one minute each and every time. The Height control light blinks at all times that the vehicle is running.
JA: Have you checked the battery's voltage?
Customer: New battery.
JA: What year is your H2?
Customer: 2004
JA: Are you fixing your H2 yourself? What have you tried so far?
Customer: Just replaced the right air spring. That's the side that began sagging first
JA: Anything else you want the mechanic to know before I connect you?
Customer: Also checked fuses. No. That's about it. Thanks.

The flashing light means there is a trouble code stored. It will be one of these in this file.

Do you have a scan tool to see which code it is?

my reader shows 'no codes'
Expert:  Chris (aka- Moose) replied 11 months ago.

Since you have no codes stored for the electronic suspension. I will not be able to help. Opting out and removing myself from this question now. Hopefully another can help.

Chris, Of course it's not your fault. I just wonder if I have the right kind of scanner to read the code. ... Of if I can read 'blinks' by jumping points where the reader should be plugged in. How to properly jump the connections for an H2 Hummer would be help enough.
