Re: Selespeed diagnosis...
if it fails with 2 seconds to me that would indicate that the pump ain;t running or the pressur eis too low
go to sensors & check pressure
then go to actuators & try operate the pump, then odd gears, even gears, hi selector, low selector
if these work then the problem lies withing one of the 3 sensors or the wiring loom.
NOTE the battery MUST BE 100% CHARGED/good to run this functions... if not it'll hang as if its doing something but its not.....
only when you are happy that the pump works, the pressur eof 45bar to 55 bar is acheivable, 100% charge battery, all the operation of the various solenoids work THEN attmept a ccalibration
NOTE2: under CALIBRATION press the New Actuator button, this ignores/erases any old calibraitons & allows a 'new' actuator to be claibrated .... i know its not new but trust me, it does help.
if all the previous is ok & it fails after pressing New Actuator, EOL Calibration, then its a SENSOR issue
