Hello everyone,

The story is simple, following an accident I completely disassembled and reassembled a GTR34 before the accident everything worked, since the reassembling my HICAS light is on, I did the diagnostic and shows the codes:
21. Vehicle speed signal not present
24. Rear main sensor input not present
25. Rear sub sensor input not present

I check all the beam HICAS, relay, fuse, one by one and all my values ***8203;***8203;are good so technically everything works.

I don't know what to do, it may be the ecu HICAS? I opened it to look but no trace heating.

Is that ever happened to anyone?
