. . . read wrong code


You should have read the codes from the DIAG module, (Menu#5), which is "AIR inoperative" as Arthur said.

Yes, some of the codes are different for your auto, but most are the same.

LOL, I figured out how you got the that code!! You interpreted the Menu #4 (4 blinks in your case) as the place to look!

Here's how it works. The LED/Sw combo reads out codes ALWAYS from the DM (Diag Module). You always go there first to see what's it telling you. That's Menu# 5.

Of course, if you have a scanner, then you can read all of the ECU modules for their individual DTCs. Make sense??
