Cruise control light comes on but cruise control doesn’t work

nafk88 · Mar 30, 2023

hey all,

my cruise control has worked just fine for last four years and just the other day I tried to use it and noticed it no longer engages. Light comes on but nothing happens when I move the stalk.

Read a couple threads and it sounds like stalk might have failed but just want to check hear if there’s a way to tell if it’s that or something else relatively easily before dropping the $100+ on a replacement stalk.

thanks for the help.

you can pin out the stalk with a good ohm meter.
that way you can make sure the electrical is good to the stalk plug.

check all of the connections and fuses.
also check the cables etc at the throttle body.

excuse my ignorance - how do I pin out the stalk?

Also I couldn’t find any good diagrams of the cruise control system to check connections. It’s one part of the car I really don’t know much about any chance you know of one iowagold?

nafk88, first check the switch located on the clutch pedal bracket, p/n 88280-14030. See especially post #4 at this thread: www.rav4world.com/threads/1998-green-light-comes-on-but-cruise-control-wont-engage.325779/

Elle___Rav4, your response and the post you pinned is an example of why this forum is so valuable. Thank you!

it is covered in the electrical service manual.

I have the opposite problem - cruise control works fine, but the light doesn't work. Any suggestions???

if you pin out the stalk
it's one pos and one ground wire

you need 4 values

roughly

0 ohms on/off
add 240 ohms +(RES)
add 390 ohms -(SET)
add 910 ohms Cancel

cruise control is shorting to ground
and set/resume/cancel are various resistance levels
on the same wire.

so on a multimeter you check for 4 defined resistance levels

yank combo meter, test the light

I attach the one page wiring diagram for the CC position. I would check the cruise control switch on the steering column first, since it is easier to get to.

1.
Put the key in the "On" position (engine not running). Press the button on the end of the CC switch. Does the "cruise" indicator light in the instrument cluster come on? Report back.

2.
Take apart enough of the steering wheel to access the cruise control switch's terminal. If memory serves, this requires disconnecting the battery for five minutes and then removing the airbag (held in place by two Torx screws).

3.
The 2-wire connector for the CC switch will be exposed. Disconnect the connector.

4.
Get a multimeter and check for continuity across the two wires of the connector (CC switch side) (1) with the button on the end of the switch depressed once; and (2) with the button on the end of the switch depressed twice. Report back. Like crisps noted, if the switch is okay, the switch toggles between 0 ohms (meaning continuity, which means no resistance) and infinite ohms (Open Loop, a.k.a. "O.L" on some digital displays). Report back.
