Greetings and Welcome to Just answer.
Check the Stud 1 fuse in the underhood fuse block. That fuse is the one that feeds power to the compressor. THe other fuse is for the rest of the system.
OK, that confirms the fuse is good.
What would help now is the code from the suspesion system. But you need a scan tool for that. All I can suggest now is check the wiring, check the level sensors and see if the are damaged.
The OBD II will only show emission codes. I Would call the dealer and ask them for the codes.
If they had the battery off, it could be relearning the adapts.
It could be the sensor, hard to say. Lets try a reset for both.
take the battery cables off and touch them together for 10 seconds, then attach them to the battery and see what happens.
did it. Idle didnt surge but SRC is still on...Is there a relay or something that controls power to that pump?
Yes, thats the one.
Jump the termials 87 to 30 in the connector and see if the pump turns on.
THat would be the best. With the number, I can tell you why it is not working and suggest even more tests.
THe relay is not a common failing point so I doubt it.
Get the code and we will continue.
IT does not have a programming, but there is a setup that is required.
IT needs a scan tool to complete the setup. THere is a chance because the module is not new that it may work, but if that does not, or it operates incorrectly, then yes it will require a TECH 2 scan tool, so a dealer or a shop that has one of these.
