I bought a Range AFM several years ago. I remember before installing it, there was an indicator on the dash that showed "V4" or "V6" depending on the driving conditions.

It's time for the first "smog test" and I need to remove the device so they can do the test. I wasn't sure if, after removing the device, I would have to drive the car a certain number of miles/cycles to set the ECU for diagnostics. I know if you replace the battery, you cannot immediately do a smog test. I called Range and they said, "NO, just unplug the AFM and drive it to the test station."

I unplugged the AFM and drove around for a bit, but I'm just now noticing there is no V4/V6 indicator on the dash! I have not driven much, so I'm not sure if it is switching between the 2 now.

Where did the indicator go? What am I missing?

Thanks!!
