2017 remote start issue

[jim larson]

Hi, my remote start would not work, check engine light on.  I disconnected battery cable, let it sit a while, re-connected battery cable.  Started car, no engine light. Put new battery in remote.  Remote start does not work.  Check engine light does not come on.

 

Any  idea why remote start will not work?  Would like some ideas before I go to a dealer.  Possibly some kind of emissions sensor or a fuse?  Can NAPA check the code if there is not a check engine light on?  Thanks

 CEL is stopping remote start

Code is still present. Remote will not work until it is cleared by problem being fixed.

 

Safety feature.

Are you sure the remote start is non functional? Mine would not work because of a check engine light. So I fixed that, and it still would not remote start.

 

Turns out that I needed to read the owners manual.

 

I did not know that I had to press the door lock button first, and then hold the remote start button to get it to .... remote start.

1.  CEL is now off because I reset the system by disconnecting the battery for 15 minuets.  But problem could still exist.  I don’t want a $400 plus bill for the dealer to replace the sensor which will get me about 1/2 mile per/g  with a little more efficient burn.

 

2. would be nice to over-ride the issue;but how do you decide the issue?  Thus the NAPA code reader.  Will it work with the CEL off??

 

3.I have read the manual at least 3 times.  I have also done internet search’s.  Yes cas cap is on as it doesn’t have one,  maybe something to do with flapper.  Maybe wire to hood latch,  and maybe other issue.

 

Going to to NAPA.  Hoping they can identify the problem.

Until you pull the code you are just throwing guesses into the wind. As long as the CEL is stored in the ECM and the issue is not fixed and the ECM self-clears the code the remote start wont work. If you clear the CEL all it is gonna do is work for a bit, then once the CEL triggers again it will lock out the remote start.

 

Start with the basics, get the truck scanned and get the code then go from there.

You could buy an OBD2 code reader on Amazon, and reset the codes every so often. Not ideal, but it may fix the problem.

 

Clearing the codes with a scanner takes about 15 seconds.

 

The code reader costs $10.
