That is good to know. The other day I was preconditioning it and unplugged before it was complete and got a CEL. It went out after the next full charge but I was wondering what that was, thanks for the info!
That is good to know. The other day I was preconditioning it and unplugged before it was complete and got a CEL. It went out after the next full charge but I was wondering what that was, thanks for the info!I find that if I unplug the cable when just finished a preconditioning but the 240v charge is still topping off the battery, it will trigger a check engine light. It has happened to me probably a dozen times over the course of 4.5 years. The light will go out on its own after a few charge cycles but I now just use my ODBC unit to turn it off when it happens. The car performs normally. I also think if you pull the plug too quickly, it has not had proper time to sense the low voltage pilot signal loss and it thinks the 240 dropped first. That is my guess as to why disconnecting the plug may throw a,check engine light.
