After changing the entire hydraulic pump, liftgate no longer responds to any keys/switches, switch on the liftgate, switch on the driver door, & the key on the key transmitter. Only the latch activates. I checked the 30 amps fuse in the cargo fuse box, which is intact. Not possible to activate/adatation by the scanner, it returns "no response from the modue".

Any guidance will be much appreciated
