    So little blue bill got one.
    And you can't find TSA info Donwload/Center /evolution bla,bla any where in the web, neither Service Tool R2 download.
    Diesel Laptop download either.
    But a 2013 windows vista laptop worked like a charm. Just plug and play. W 7, 8 and early version of W10 work too.
    So happy than even check the fault code.
    My Evo click the fuel pump and the buzzer but no crank at all, if some one got and idea let me know. Already change the rocker switch, belts, filters, condenser and radiator fans, clean alternator connections and grounds on apu and ground in the control box inside bunk, fuses at the battery box and 50 amp and 3 amp fuse at the apu.Thanks.

    Look for a small wire going down to the starter,it bolts on right with the big starter wire.The small wire usaully breaks,then it won't start.Happened to mine and another driver.

    That small wire is the one that picks up the voltage signal,it's probably broken or rubbed through.

    Was rough today, freezer ice bin froze, washer machine broke having a beer now.
    Well got 2 broken wires the white coming together with the red one from truck battery positive ( 2A) just behind the apu by the frame and the blue terminal at the alternator, still no crank. Cheers

    Might have to stop in at a TK shop,have them check it out.I got mine running but it was blowing warm air instead of AC.
    Took it in to the shop in Houston,the cabin temp sensor was bad they changed the control box under the bunk and fixed it.Very good diagnostic and repair price.
    I was at the terminal in Louisville,talking to another driver about the APU,he said the little wire was broken on his.I went out to my truck and looked,sure enough the little wire was broken on mine too.
