HOW TO By UncleBob
This is a guide to fitting factory cruise control to an auto petrol Rav4.2
had a productive afternoon fitting factory cruise control to my Auto Rav4 XT3 2004, it's almost a plug n play, with two wires to pull from one plug and fit into another.
FIRST OFF YOU FOLLOW MY GUIDE AT YOUR OWN RISK, THIS IS HOW I DONE IT, MIGHT NOT BE A TEXTBOOK METHOD BUT IT WORKS AND IM HAPPY WITH IT
First off disconnect the battery, the Toyota workshop manual says leave 90 seconds before starting work but I would give its 5 minutes or go make a cup of tea
The airbag has to come off, this is held in by two T30 torxs bolts recessed on the back cowling of the steering wheel.
Always a worry playing with airbags but the manual claims the capacitor has discharged after a few minutes so is deemed safe.
I left it connected by its wires as it's just something extra to break if I pull them off . With the airbag off you can see the wiring plug I've removed from its holder...
Also removed the audio switches,don't forget also remove blue horn wire from airbag chassis
,one Phillips screw and it pulls away..
The wiring harness that I purchased with the switch needs two of the wires removed from that plug and refitted into the audio plug in THE VERY SAME HOLES,one is white with black strip and the other is black, the wires seem to be fitted for life so cut the old plug down until the wires were free.
Old plug...
..and fitted into audio plug...
Refit audio switch to steering wheel, and connect wiring plug into the cruise control switch....NOTE at this point I have no idea if this is going to work, so done a test before drilling hole for switch.
The test was done by removing the blank plastic trim on the other side of steering wheel from the audio switch....
Then let cruise control switch hang out and refit airbag...reconnect battery and check for CRUISE light on dash panel.....
I was very relived to see this light
Now disconnect battery again, and after 5 mins or so remove airbag, next stage is drilling or making hole for cruise control switch, I have seen a few people cut it out squire but felt it left the workings of the switch showing, so I decided to drill a hole with a hole cutter, there is no template for this so after much though .......the hole was cut.
I added a cloth covering to the rear of the switch and glued it in, now at this point the hole could have been 5 mm further back but as the functions of the switch are up, down and forward, no harm done.
The hole has to be close to this size to wiggle the switch in from the steering wheel outwards, the securing screws have to be added, then reassemble Airbag and reconnect battery ......and roadtest.
Pleased to say all works as it should, and my outlay was £39.00 for a used switch and harness.
Parts can be purchased new at around £130.00 but only some dealers will sell them to you, due to the problems with sticking cruise control reported in the media, I believe it's down to floor mats or pilot error !!!
