Failed inspection today

[mzr2240]

Haven't done any mods, replaced the alternator a couple months ago. Drives great, no issues or lights on the dash. I use a range obd plugin but I took that off and it still failed. Any suggestions?

Try another shop. If your O2 sensor is not working you would have a check engine light.

We've heard that unplugging the Range device can reset some of the monitors, although it seems to vary. Anyway, your pic is showing that there are three monitors that have not completed, and usually you're allowed only one incomplete monitor. You'll need to drive it for a bit without the Range device to get the monitors to set, so be sure to re-check them with your scanner before going back to retest.

In Jersey all monitors need to be set, if not you fail.

I use a range OBD plug in my Yukon. I’m fairly certain it also caused my systems to fail this past week.

Have to do a drive cycle with the range unplugged then try to get it tested again

I'll try driving it around without the range device in, we'll see if that helps. It was failing on 4 monitors but as soon as I unplugged it I only failed for 3. I'm in Tx but I don't know how many I'm allowed to fail here. Thanks guys

I don’t think any emission states will let you fail any of the test.

Probably true. But we're talking not about failing, but monitors being ready.

Here’s the work around to manually reset the equipment. I had my Tech2 plugged in during the drive cycle so that after each drive cycle I could verify the BCM showed success.

Thank God I never was around the tool trucks when I was in the trade. There’s a tool for anything and everything. In the HVAC trade there was also a service call for every tool. After being out in the field for two years there’s no way I could have made it if I stayed in the buss in CA at the...

Yeah I agree we got off track with the terminology. But monitors that aren’t set would be a fail in the eyes of the inspector if I’m not mistaken

But no need for diagnostics, just need to complete drive cycle
