Check engine light on

Tue May 31, 2016 4:21 pm

12v battery went dead. Jumped it and left key in ready for 30 mins. Then completed charging with ext charger. That all went fine. Plugged main charger in and in a mental slip turned key to on then to ready. Check engine light (stop car and call dealer light came on). Switched key off and completed charging of drive batty overnight. Call dealer light stayed on. Took it for a 45 mile spin all normal except the call dealer light stayed on. Disconnected 12 v batty for 30 secs hooked it back up and commenced charging drive battery. Call dealer light still on. I am in Abaco Bahamas there is no dealer to call. Hope someone can help.

Had this happen to me. It appears to be some overzealous programming that makes you go to the dealer so they can check why the 12 volt battery went dead. This is triggered when the battery is too low for the vehicle to either start or charge. Unfortunately, without a dealer or their MUT-3 and computer tool, this light will remain on.

Do you know what caused the 12 volt battery to go dead? Did you try to start or charge it before jumping the 12 volt battery?

The "check engine" light is also known as the "dealership $ sign". Its likely that the flat battery has just tripped one of the sensors. Some faults reset after a couple of cycles however others remain until they are reset. I have plans to build the feature to find out the fault code & reset it (assuming its trivial) into my App EvBatMon, however it hasn't risen to the top of the feature requests yet.

i don't think you can read the fault code with an OBD reader--it is not using the same CAN protocol that ICE cars use. i've tried and the reader could not identify the protocol.

Torque and the i-MiEV don't get along. Just opening the app causes the MCU Warning light (car with !), RBS, ASC, and ASC Off lights to come on. A simple power cycle clears it, but I don't recommend using Torque.

You can bet with that announcement that code reading will jump up on the request list for EVBatMon (which is working well except for random value spikes and the accompanying beep).

Batty went flat because vehicle stood for 3 months at vacation home. Next time I will disconnect or leave on trickle charge. Is there no way to reset?

I experienced this also while measuring the 12 volt loads. At one point while putting an amp meter on the 12 volt battery I think the 12 volt became disconnected while the car was in ready mode and the exclamation point symbol came on.

The car ran fine and i used it for months with the light on. I eventually got it rest by the dealer.

We address this 'storage' issue in various threads on this forum. Anything over about three weeks and the 12v battery should be either disconnected or attached to a smart 'float' charger (not old-fashioned 'trickle' charger). If outside, a very small solar panel with regulator also works great. With OEM 12v batteries now with four-year+ lives (and thus diminished capacity), I would slap on a 12v float charger even if I left the car for a week.

Excellent data point.

That's sort of what I figured and if it was me I simply wouldn't worry about it as the 'failure' cause has been identified.

I am prepared to add the feature to EvBatMon if you are happy to test it for me? It will take about a week.

I am not familiar with that device/software but it sounds like something I should have as there is no dealer in the Abacos.
