After AEM install, screen reads "test"

17MaroSS · 03-30-2021, 09:01 PM

Hello everyone. I just finished installing full bolt ons and after installing a AEM wideband and starting the car, the screen just reads "test". The mode and set buttons don't change anything and there's nothing written about it in the manual. I would appreciate some help here. Thanks in advance!!

Which aem did you install?

Usually if an aem unit gets stuck on test or heat up mode the power source for the gauge isn’t a strong enough or reliable source. Where are you getting 12v from?

It's the aem 30 0334. I didn't know a switch can be weak. Thought it either has power or doesn't cause it's a 12v car. No? This is where i put it

Double check your ground. Connect the power directly to the battery. If your power and grounds are good, you may have a defective unit. The next step would be to contact AEM.

I took my power from the cigarette plug and no issues. I doubt it's a power issue snice you want directly from a fuse. Are you sure your on the correct side of the fuse?
