The lights flashing indicates a failure. You need a scan tool to determine the failure.
You will need a shop to help you.

I scanned for codes already and none came up, I saw on a test for sentra that you can test the switch by presing the brake while driving and pushing the set or excell button and if cruze light does not flash it is the switch. I was wondering if those test done on sentra will also work on the altima, I would also like to know how to test the pump and adjust the pedal swich.
