Guys I had a bizarre incident in the evening whilst working in the garage. There I was in my garage cleaning up and putting some parts away when a chap in his 8th Generation Tourer pulled and asked if I was Honda technician?. I said no to which he said come on you got all this Honda signs up and I have seen you working on your cars.. To which I said sheepishly ok the games is up ..how can I help. He showed me his mint 2011 Tourer in black and found on pressing the tailgate button the boot will not open. No beep, no audible warning nor could you hear motor engaging That got me thinking this looks like a total failure or simple blown fuse. Straight into the garage whipped out the HDS and HIM and put the kettle on. Scanned the car and found the Front near side door window not working and few tailgate specific DTC. I did some tailgate specific hard coded commands by the HDS to initiate some sort of force intervention.. not a thing. I then carried out a Tailgate ECU reset still nothing ..this is getting complex by the minute. I diverted my attention to this N/S/F door and pulled up the wiring diagram on the workshop manual to see if there was a relation to the tailgate. On reading up and seeking out how the multiplex command were sent it became apparent the electrical multiplexing commands are sent via passenger side window switch. Removed the door card pulled out the switch to find it really tacky and sticky.. Asked the owner if they had spilt something on the switch he said yes the partners spilt half a can of fizz drink on the switch a week ago and ever since the tailgate has not working. Bingo!! found the culprit Stuart was very impressed that I found the source of the problem he will his car at the local dealers tomorrow for a replacement switch. I have asked him to join up on the forum so he can tell you his tale .
