    Default 2011 Volvo XC90 Non start / No Comms to TCM

    Here's a nice one. Volvo XC90 (AWD Auto) had a flat battery. Only codes present on a couple of modules was no comms to transmission control module. Also nothing lit up next to gear selector. Non start because car doesn't know if gear selector in park or neutral. If ignition switched on it is possible to start engine by shorting correct terminals on starter relay socket. Solution to reset TCM on this one was put IGN on and pull F9 (15A) in engine fusebox and put it back in after a few seconds. Disconnecting battery wouldn't work for some reason.
    V Series TMS470 / EEPROM data - encryption / decryption, totally pwned.
