mas Posted November 3 Share Posted November 3 (edited) There I was minding my own business going about 80 in 5th gear and it just stalled, single horizontal bar flashing, followed by the temp blobs flashing and on the 2nd flash, the gas blobs got in sync with the temp blobs and flashed together. Slowly pulled over, slid the shifter in neutral but as the car slowed, it was never in neutral and chugged to a stop in gear. Is the Smart just being a Smart? Does it know I am looking at another vehicle? I did the Smart thing, pulled the key, waited 20 seconds, started right up and was back on my way. It did it again 5 minutes later and nothing since then. My search only gave me the 3 flashing bars (which has happened to me twice before). Comments?

Willys Posted November 3 Share Posted November 3 Hmmmm.....?????? I hope mine's not as Smart as your's......I too am looking at another car....lol. I am after something that doesn't require you to become a computer genius to be able to enjoy it. No, not getting rid of mine yet but it has crossed my mind I will admit....! Sorry, no I haven't experienced this issue myself. Hmmm....? I would be searching every ground pin location for bad ground. Then if that doesn't help start removing every sensor to see if any connector is corroded or not in tight? Then I'd be going after the SAM and ECU to search for more corrosion issues. Just make sure you disconnect your battery before touching anything ECU related. It has capacitors which hold a charge and it is capable of frying itself if you short any pins out. Ask me how I learned this lesson...!!!!! Keep us informed....and what are you looking at that the Smart isn't happy about...? lol Quote Link to comment Share on other sites More sharing options...
Nigel Posted November 3 Share Posted November 3 My understanding is the single line is a CAN bus error. I haven’t seen anyone post anywhere definitive to look. 1 Quote Link to comment Share on other sites More sharing options...
smart142 Posted November 3 Share Posted November 3 It's a long shot but..... I would check the coolant level. Quote Link to comment Share on other sites More sharing options...
mas Posted November 25 Author Share Posted November 25 Just to review this issue, inspected the coolant level, it was a tad low (I added a cup or 2 of coolant) and the issue has not reappeared. 2 Quote Link to comment Share on other sites More sharing options...
MikeT Posted November 25 Share Posted November 25 (edited) CAN Bus error - wiring issue. I'm not sure what it has to do with coolant. Edited November 25 by MikeT Quote Link to comment Share on other sites More sharing options...

That's what I experienced when the coolant level was low, or when air got in the system. Quote Link to comment Share on other sites More sharing options...
MikeT Posted November 26 Share Posted November 26 So there could well be a CAN Bus error too? Quote Link to comment Share on other sites More sharing options...
mas Posted November 26 Author Share Posted November 26 would the CAn bus error throw a code? No CEL in my case Quote Link to comment Share on other sites More sharing options...
stickman007 Posted November 27 Share Posted November 27 No CEL only means that the ECM did not logged a code. This could potentially be that the ECM shut off and that’s why it did not log any codes. If the ECM drops out, the CAN will have issues. Perform a load test to all your power/grounds to the ECM. If you have a scanner that’s capable of connecting to your ABS, airbag, SAM, or cluster module, you might get fault codes that will point to the culprit to the CAN issue - which module is dropping out. 1 Quote Link to comment Share on other sites More sharing options...
