Problem:
Added a spare key today to 2022 Toyota Kluge / Highlander HV using Autel IM508s along with Autel universal key for Toyota 8A.
Backed up eeprom file via OBD, followed guided add key, and programmed in successfully.
However trunk open button not functioning.
Did eco to immobiliser sync and all other buttons /keyless entry etc working great but need to get trunk button working.
Had same issue recently with a 2023 Rav4 hybrid. Any input?
Solved.
RECTIFIED TODAY BY CONNECTING XP400 BACK UP TO 508s and first reading info off universal key I generated yesterday for 2022 Toyota Kluger / Highlander then updating – changing assigned function for trunk open button from trunk to tailgate
TURNS OUT ELECTRIC TAILGATES IN SUVSV NEED A CONTINUAL 3 TO 4 SECOND SIGNAL WHERAS THE DEFAULT IS TRUNK WHICH ONLY GIVES A SHORT Half second pulse.
Tested and now all smart functions etc working like a genuine one.
