Question about 1997 Hyundai Elantra

Open Question

My 1997 Hyundai Elantra will not connect to the Smog Machine, so my car can not be smogged.

I went to get a smog check done on my car because I needed it to get a new registration. When they hooked up the computer to my car they could not get a connection. I even too the car back to the person who did the smog check on this same car twice before and they could not get a connection to their computer, they even try hooking up a scanner and still no reading. Any help here?

Ok you will have to have it scanned. It probably has cylinder misfire codes and random cylnder misfires. You could need spark plugs and or coils. The scan will tell you exactly which cylinder is missing. That will cure your problem and remember to change your oil and filter right before you go in for the smog test. Also if the car hasn't been serviced in a while it would be a good idea to replace the air filter and fuel filter.

CA you can take the car to a referree and get a one time waiver if you have spent a minimum of $450 on repairs not including smog fees. Gives you two years to get it fixed. Smog Referee Call Center
Toll Free: 1.800.622.7733
You can also sell the car to the state for "up to" $1,000

You will need to get it scanned and get the codes for the problem. If it failed the test due to emissions I would almost guarantee it will be your oxygen sensor or cat

2006 hyundai elantra obd won't communicate with smog check station


Just to clear things up, having the monitors ready has nothing do to with OBD Communications. Ready or not, it will communicate. The original issue here was a station with a bad scanner. she did the right thing trying somewhere else and following up to get her $ back.

Cannot get the 2001 Hyundai Elantra to pass the emissions test as the light stays on. When we shut it off, it will come back on after a few miles.


You need to have your check engine light checked to see what the code errors are and repair the problem so that it will pass smog. The check engine light is on telling you that something is wrong with the vehicle.

2000 Bettle won't connect to smog machine.


The term "flash" has to do with the on board OBD2 computer flash memory. New software updates or sometimes performance tuning will be programmed to "flash" this memory effectively changing certain preset values such as ignition timing and air/fuel tables. Most cases i have experience with are for the performance market but have been developed in accordance with factory guidlines.
