I have a 2012 Volvo vnl670 automatic no I-shift. And in the past week this L keeps popping up and won’t let me drive or reverse. Usually there’s an E there. Does anyone know what it means. Thank you
Limp mode. It should be the button on the back of the I-Shift. Limp Home Mode - Volvo i-shift transmission Operator's Manual [Page 25] | ManualsLib
Does that come on on its own. Because to be honest this is the first time I’m seeing it. And I what does it do. Thank you
I don't know a whole lot about it, since I haven't had to use it. I think you only use it when your transmission is damaged and you need to get off the road or around the yard or whatever. I don't know if it can activate by itself.
E or P are Normal modes of the transmission. L is a Fault mode. Your unit is not operable. If you have a Volvo shop close by drive it there. By pressing the push-button L at the back of your gear selector. If not, tow the unit. Once in the shop ask them to do an instrumented test drive using the Performance Tech Tool. It can be done in their yard. The Tool will catch anything that causes L mode to activate. The most common causes that activate an L mode are located at the brake and throttle pedals. Switches and sensors. Another one can be the speed sensor at the back of the transmission. Or the transmission itself. The 2012 Volvo 780 that I own did the same. Instrumented test drive scheduled for next Monday. I'll post an update.
