Creeping down our steep driveway after a 3 mile hilly run. Using the engine to help break. I'm in 4WD and Low "gear" mode. Suddenly there is a "release" type pop and the engine is no longer breaking as sometimes happens over a certain speed. No problem I apply more breaks and come to a rest down the hill. BUT this time the "back up" alarm is beeping and now the engine is just dead. Error code was initially 54C 2 but after resting overnight it now says 54C 3. As soon as the key turns on I get the alarm and nothing from the motor. It does look like the flashing engine thing shows a square box in the middle front is flashing. I have tried to find those codes but no luck yet. I wouldnt know what to do with them anyway. Any insights appreciated.--Bill
No idea, as you will find out, Massimos are a do it yourself project, no help from the manual or the factory. I can't help you now because mine is a at my farm 160 miles away.
