We have a 2013 Fiat Pop that we purchased about a little over a year ago. Back in July, the battery died and we replaced it. It happened to be the same month that our registration and inspection expired. I took it in for an inspection a week or so later (having forgotten about the battery replacement) and the smog readiness tests had not been completed....no big whoop, we've had this problem with other cars we've owned; just drive a handful of cycles, put on a few dozen miles on the odometer and we should be good.


we use the car for just short commuting to and from work (<10 mi each way), so that wasn't a big surprise. So....we came back a week later after putting in about 150 more miles, and still not complete. Read that some people had to put in up to 500 miles before it reset, so a few weeks later (after it had expired) still no dice. At this point I started looking up other ways to get the vehicle to complete the tests -- tried about 3 or 4 different tests (eg. cold start, idle for 5 minutes, bring up to 2,000+ rpm for 10 minutes, come down to 25 mph with no brakes...etc.). All with no luck. I Got a new OBD reader that reads the smog codes and over 3,000 miles later, still no results.


I finally broke down and took it to a dealer and they rebooted or flashed (forget which) the ECU and here we are 2 weeks, ~500 miles later (and still doing a few of those cold-start tests) and still no changes. They said if that didn't work, they'd have to replace the ECU and said it would cost $1,000.I thought that was a bit high -- checked to see how much a used one would cost, and saw that they run in $50-150 range.


I wanted to check to see if anyone had any advice -- is there any thing else I should check before going the replacement route? I've never replaced one before but it doesn't appear to be too difficult to change the ECU -- are there any pitfalls I should be aware of? Will I still need to take it to a dealer once a replacement one is installed? The registration at this point is over 3 months over due and I've already been stopped twice and gotten off with a warning...I'm trying to avoid another encounter with the local police. (I lucked out; I had my ODB reader attached and explained the situation)
 
Hello and welcome to the forum.

Sorry to hear about your problem.

In Europe, emissions testing is done by directly measuring tailpipe emissions, not by reading information stored by the ECU. It's likely that North American models have a completely different ECU setup, so your question can only really be answered by someone familiar with the cars produced specifically for that market.
 
It looks like I'm having the same issue. 4 different sensors/ tests still reading incomplete. Appreciate any help with this.
 
I read up on my warranty, and it looks like there is a federal mandated warranty on the PCU/ECU for up to 80,000 miles/8 years in relation to emissions failures. I'm going to have to go back to the dealership to get them to fix this since I'm tired of dealing with it.

Yesterday, I checked to see if I could do an ASM emissions test (as opposed to the ODB scan test) and none of the shops that were open would do it...I didn't get a straight answer why -- not sure if it's a technical issue or a legal issue.
 
I too am stymied by ODB monitors not resetting, and I’ve driven 800 miles (mostly highway). So frustrating. Btw, you shouldn’t need a reader to tell if the car is ready - if you turn key but don’t turn on car, the check engine light will flash after 15 seconds for a few seconds and then stay on. If your monitors are ready it shouldn’t flash.
 
I'm just past the 80,000 mark, so I cant claim a warranty issue. IF you get an answer from the dealership, please let me know. Thanks

OBD Readiness Checks or Drive Cycle process for FCA (Fiat Chrysler Automotive in the U.S.) are set by Chrysler because it is the host company for FIAT in the U.S.

Since this is my 1st post I am not able to add any hyperlinks.
However, if you google search:
fiat chrysler drive cycle
You will get various methods to complete the drive cycle checks.
Its very tedious, and typically I have to go find a flat, smooth, traffic free rural road, usually super early in the morning to preform the OBD Readiness / Drive Cycle test.

Also the majority of these test involving emission rely on engine and exhaust temperatures being met.
Thus, if you have aftermarket exhaust your exhaust temps might be lower at the 2nd Oxygen sensor, and will make the process very difficult if not impossible to complete.
