Hello

I'm Working on TCM FB18-7 48v and have error code 216 displayed on the dash. check the flash codes on the driver board and give me code 59 CSLU problem. I have changed the sensors with new ones. I have also tried swapping sensor with others on the liftruck to see if the code Changes. still the same code. changed the wiring harness as precaution because problem is intermittent. I still get the error code.

at this point I believe it may be the board.

Can anyone give me a hand?

any help is much appriceiated
