Engine light came on after fuel fill up.

The engine light came on after we fill the car with fuel this afternoon. I have read on other forms that topping off your gas tank or leaving the fuel cap loose will cause the engine light to come on. Some owners took the car to there dealers for repair and some remove the ground lead on the battery which remove the engine light. We have put 50 miles on the car since I remove the ground cable and the lite has not come back on.

(it seems like they cram a lot of crap in the passenger footwell, flat repair kit, battery, etc...); ▶ Reply to This

BTW... where did you mount your display?; ▶ Reply to This

My sun glasses are too wide for that space so its not in use. Its not a permanent site because I'm going to try a couple of places before I start drilling holes in my smarty!... That location gives me view of only the two right side monitors.. there are 4, top left and right, also bottom left and right. Now you can assign any function to any corner.. tr, tl, br, bl.. So I put rpms in the TR and mpg in BR. those are the most useful driving. The other two I randomly assign Volts, manifold intake temp.. throttle %, ect. its fun to see the cars inner specs at work.; ▶ Reply to This

After reading your post and mr. bad examples I order one online this afternoon. It would be nice to call the service department with a fault code from the scan gage rather then driving 400 miles round trip to find out the engine light was no big deal. Thanks.....; ▶ Reply to This

If you sit in the drivers seat and run your fingers down the Knee restraint (the clothed belly of the dash) right after it ends in line with the accelerator pedal you will feel a tab kind of like the protruding tab of the gas lid... once you find it get out of the car, kneel and you will see the little lid under there. its a little hard to click open but once you do you will see it just hangs straight down. you plug your scan guge in, and its almost ready to go.; ▶ Reply to This

Thanks for the pic. Is there a panel screw missing to the right side of the opening?

I'm hooked... found the US ScanGauge web site. They don't ship Internationally, but they have a link to Aussie distributors; one of whom has a web order system. May have a 'Gauge in the next few days and then be wondering where the port on the Subaru is.... canna wait for ma smart to be built.

Have you had a chance to verify the trip and mpg readouts yet?; ▶ Reply to This

I've had my scan gauge for awhile, then got injured (broken elbow, ankle, and heel). I'm still in a leg cast and just tried to find where to plug it in. I can hobble back into the garage and install it -- since my hubby won't do it for me. He didn't want me to buy the gauge. He'll be surprised how nice it is once I get it in.

AGAIN - THANKS A MILLION!; ▶ Reply to This
