check engine light

AVIMAX · 05-28-2014, 11:01 AM

Does the key fob store error codes? Will an error code associated with the check engine light be readable on the key fob? Just wondering if I can stop by a dealer and have someone read the key to quickly check it without making an appointment.

Yes it does. Every time I take my car to the dealer my CA gives me a print out of the info stored in the key fob.

so if you got JB4, make sure your key syncs without CEL on dash.

I'm curious, how do you force key to sync?

reprogram the remote or remove battery and put it back in

But i think remote syncs every time you start car because remote keeps track of mileage on car. But I don't know if remote removes codes from itself or keep history. This little turd can cause problem.

What other info does it store?

I popped into a dealer when an engine fan error msg appeared (told me to drive cautiously and seek service assistance).

When I arrived at dealer I explained I had been driving normally.

The assistant scanned the fob and smirked at me (I just did a quick sprint up the road at peaked at about 110mph).

When I saw the look on her face I joked that I was going fast to get more air though the engine.

Neither of us sought to confirm or deny....!

So, can they seriously see all that info? Max RPM as well??
