Check engine light when pressing BC/resetting speed
Hi,
Today when driving I long pressed the BC button to reset the fuel consumption and average speed. The check engine light started blinking and the rev counter stopped and was stationary on 0 and 1, (toggle between 0 and 1 if BC was pressed again). The blinking check engine light disappeared when long pressing the BC again. I replicated the issue twice. Any idea? |

That might be some MultiMap etc switching method.
MHD+ Menu System On supported MHD+ platforms (currently F/G-Series), entering into “mapswitch” mode is not only just for mapswitch. It is actually a more advanced paged menu system, with 3 different “pages” as of current release. You enter into the menu system the same way you did mapswitch (F/G-Series: press and hold either the cruise control SET/LIM button or the BC button for 2 seconds). You will always enter on “page 1”, which is designed by a pattern of one CEL blink at a time. To change pages, quickly press the SET/LIM button or the BC button. The current page is always indicated by the blink pattern of 1 / 2 / 3 blinks in a row. To exit the menu, press and hold again like you did to enter. Page details are as follows: Page 1 - Mapswitch This is the normal map switch you are used to. UP/DOWN on the cruise control rocker will move the RPM tach to your desired map selection. If you only have 1 active map slot, you will not be able to move the tach from 1000 rpm. You will still have access to page 2 and 3 though. Page 2 - Exhaust Flap Control Page 2 allows you to control your vehicle’s exhaust flap on the fly. There are three settings you can switch between (again using the UP/DOWN rocker). ● 0 rpm = OEM exhaust flap control, no forced override ● 1000 rpm = exhaust flap always forced open ● 2000 rpm = exhaust flap forced closed (note: this will only apply up until a certain load threshold for safety) Page 3 - Ethanol Content Quick View Page 3 will show the current Ethanol percentage of your fuel (when using an appropriate CANBUS ECA kit). 1000rpm = 10% Ethanol, up to 7500 rpm = 75% ethanol. If you need to see E% greater than that, you should log it or place it on an MHD Monitor gauge. |
