RAV4 cruise control

[Vodka11]

I have fitted a cruise control stalk to my 2003 Rav but I can't get it to work, any ideas of where I went wrong.

Hi, I have fitted a cruise stalk to an petrol XT4 2004 which has been working for a few years, here are some possible reasons why your switch may not be working.

I seem to remember that there was a change to the XT4 in 2004 that included a drive by wire throttle body. (ie there is no direct mechanical connection between the throttle body and the throttle pedal)  If your throttle body is linked by a cable to the throttle pedal, I suspect the simple addition of a cruise stalk will not work.

If you have do have a drive by wire throttle and have a manual transmission, have you fitted the clutch pedal switch ?

I am sorry its been such a long time since I fitted this mod that I can not provide any precise wiring information.

hope this helps

Hi and thanks for the reply, it is a fly by wire on my rav, I will look into the clutch pedal switch and give that a go.

Hi IanXT4,  I've checked my clutch peddle and guess what.......... Yes there is a switch on it. Don't know where to go now, think I will take the air bag off again and check the connections that end.

Hi, my Petrol 2004 XT4 definitely did not come with a clutch switch.  I had buy it from my Toyota dealer and add it to allow the ECU/cruise control to know to switch off when the clutch is pressed. (switch cost about £15) The car wiring loom was wired for cruise, so all I had to do was add the switch and connect it to a nearby connector.

If you have a switch as standard on the clutch, I suspect its possibly for something else ?  I doubt that Toyota would spend the money on a switch that is not used  ??

Is your car a diesel ?, could there be a reason why the car ECU would want to know that you had the clutch depressed ? (I googled but could not find anything)

When I fitted the cruise I spent a few Euros (3 euros for an hours download) and downloaded all the wiring schematics/connector locations etc for my specific car from the Toyota web site.  From this I could see what each connector and switch did. I could also see that the wiring loom was fitted for the cruise control.

Sorry can not be of any more help, but my guess is your problem may lay with an input from the clutch to the ECU :-)

Good luck

Thanks for the help, yes my rav is a diesel, not sure about the switches though, there's two switches on my brake peddle as well.  Think I need to look into this more deeply............ When I have more time.
