SERIAL NO :611877000952
PART REPLACED : PART NO => 8409436
Need someone's assistance to fix a problem of above truck. We imported the PCB (p/n8409436 ) and installed onto the truck but the truck does not work and the errors messages FE 17 followed by FE42 displays and blinks. However, customer has an identical truck. We replaced the new PCB to it and the truck worked confirming that the PCB supplied by us is NOT defective. However with this truck (the truck that is working) error FE55 comes and goes but all the functions work
Do we require the Service Software to make any setting to bring the truck (the one which is not working) to working order ? desperately looking for help !
