Fixing Steering Wheel Control Button

We bought a new (second hand) car and adopted some ‘niggles’ with it. One of those was that the <SET> button on the steering wheel control did not seem to work. 

Centre info/set button did not seems to work.

Spoiler alert: Although I think the disassembly-clean-reassembly exercise was useful, as the button was sticking a little bit because of buildup of gunk in its working, I suspect that it was actually working to start with. Its just the button does not do a great deal by itself.

  1. I found that if you hold the button while turning the key then you can get into some car settings (in Japanese) – you can change clock, turn on/off dial startup animation, set your birthday(?), set your anniversary(??).
  2. To reset the trip computer (Trip A or B) you hold the <SET> button and simultaneously press the trip reset button in the dash. This is the ‘conventional’ one which I randomly noticed was there and was surprised to see. I had assumed all the electronic screen and steering wheel stuff would mean this conventional trip button would be superfluous. Kind of weird. Anyhow, to change trips you press that button – you dont seem to be able to reset trips and change trips through the screen system or steering wheel controls.

Youtube video below is pretty useful as a starting point – he is replacing the steering wheel.

  • Heed the video author’s advice to disconnect the battery and discharge as residual charge to avoid ‘testing’ the airbag.
  • I think the guy in video wings it with wrong type of screwdriver to open the two first captive screws either side of the wheel. I found  them to be REALLY tight and would recommend getting hold of correct tool/ screw-head. Its a Torx T30 Socket.
