I have a 2007 Bluebird all american . If you start the bus everything will be fine for a few minutes . Then a light comes on and says range inhibited transmission cuts out . I got a code of P0882 low voltage . My jpro says it starts out at 11 volts and when the light comes on shows over 13 volts . Any ideas ? Thanks !!!
the code is for the battery power low, pins 10 and 70, could be a bad battery, or charging system, as per Allison it should set this code for under 9volts load test the two wires with a light or power probe, from memory i think most only have one wire that goes o power and there is a splice before the TCM that gives you the two wires , so check the splice also , low voltage only has to happen on one of these wires to log code

Thanks Bluenozer for filling me in . Now would it be possible to show which pins are used on the connector ? Maybe the plug is numbered ? I have never had to work on the power side of an Allison .Only one time had to figure power on one in 30 years .I guess I am at lost too . My laptop shows 11.9 volts using allison software .
