Hi,
When I installed Automatic, I had a pre-existing check engine light on in the '99 Acura. Automatic does not indicate any problems with the engine. Will I have to wait for the car to throw another code?

Hi John
It really depends on the code. Which code was set?

Regardless I would clear the code and watch for it to set again. If you can share the code,I can likely give you an idea of what is wrong.

I don't think that Automatic registered a code.  The check engine light came on before I plugged Automatic in.  When I look at the app it indicates that the engine is fine.

There are. "Deep" codes that may not register. Is the light remaining on?

Ok...I am reviewing some documentation on your vehicle chassis. Need a few, will respond with a possible course of action.

John,
After reviewing the documentation for your vehicle, I am 99% convinced you have an SRS fault (airbag).  Certainly the first thing that you may think is "why won't the Automatic Adapter tell me that".

Well, the Airbag codes are a special set of codes that are not obtained by standard OBD II calls.  In private emails to the Automatic team they have acknowledge this fact and have indicate that it may be something they support someday...but not now.

Note that airbag faults do occur, they occur much less than standard faults.

My suggestion: Take your vehicle to an AutoZone or O'Reilly's.  They will read the airbag codes from your car for free.  If it is an airbag code I most certainly urge you to get it looked at.

Do let me know how it goes.

Hi there, John. Does your car by chance use the same light for maintenance reminders? You can check your car's manual for more information on this. If so, that may be why we don't display anything for the check engine light. We can only read certain codes from the computer specifically related to trouble codes. As RPS mentioned above, we also can't read other protocols, such as maintenance reminders, ABS lights, etc. If you send a message to help@automatic.com, our tech support team can review your account in further detail and determine whether this is the case.

That is a good point.  While I don't have complete recall on all dash layouts - if I remember properly, Acura's in the late 90's had two separate lights.  One indicates "MAINT REQ'D" - which would be for oil change is needed.  The other would be the "Service Engine Soon".  Likely a picture of an Engine with the word "Check" in it.

If it is the former then follow this procedure to reset the light (assuming there is a Select Reset button on the console:

With the car off, and key out - Push and hold the Select Reset button.  With the button depressed, insert the key and turn the car to the 'on' position (do not start the vehicle).  Continue to hold the button down until the maintenance light starts to blink and finally go out.

This should have reset your light.

Again - hope this helps.

Hi All, 

I have this exact situation and am grateful for the suggestions. My vehicle is a 2005 Toyota Highlander and I'm pretty sure it uses the MAINT REQ'D light for periodic maintenance. I hadn't realized those codes wouldn't be displayed by Automatic, nor the airbag related ones. Good to know, thanks! I'll go have it checked at one of the parts stores mentioned. I suspect I need an oil change if nothing more, could it be for that? Or are the periodic maintenance alerts for more in-depth maintenances? 

Thanks,
Tom

Hi Tom! Great name by the way :)

It's difficult to say exactly why your "maintenance req'd" light has illuminated, but as mentioned above, it's probably best to take your car in for a diagnosis. If you'd like to read more about the "Check Engine" light feature and the engine codes Automatic is able to read/interpret, check out this topic.

I have a very similar problem with a 1996 Buick Regal Gran Sport. My “Low Coolant” light was on before I installed the Automatic device for the first time (I have checked the coolant level and it is correct). I was hoping that Automatic would help me diagnose this issue, but the app has consistently said “No problems detected” from the first time it connected to my car. At the very least, I was hoping that Automatic would allow me to reset the code so that the warning light would go out. Any suggestions?

Hi Rob-

Automatic can't detect or clear low coolant lights. It can only detect, diagnose & help you clear the Check Engine Light. Here's a FAQ with more info on that.

My experience is that an existing "check engine" light is not detected until after a drive. I have cleared codes that existed (with the program showing "no issues" once I made another trip where the indicator was detected after the drive., and an option to clear was then provided. Car is a 2001 Bentley.
