Cruise Control Troubleshooting

[wgrenning]

Hello, I am a new member and just bought a used 2004 Corolla LE. The car works great except for the Cruise. It will not set. Is there a troubleshooting guide someone may have put together on the forum? I searched w/o any luck. If not where do I start? Thanks !! Wayne

When you say it does not set, do you mean the cruise shuts off, and the light goes out, or it does not keep the speed? Are you auto or manual?

Check the actuator under the hood and clean the connections, also check fuses, the 3 brake lights, and brake fluid. Do you have any check engine lights on?

Also, check a switch up on the break pedal that disables the cruise control, maybe that switch is unplugged or bent.

With the manual, you cannot have any pressure at all when you try to set the cruise.

Try this it is worth a shot, hold the back of the clutch pedal with your foot then try to set the cruise. Any normal road vibration it will deactivate the cruise, for some reason, the clutch and CC is really sensitive.

Check 19, 22, 29. I doubt that they are bad, but it will help to eliminate them.

If you cannot find a problem, it is likely the clutch switch or the brake switch for the CC. Look at the top of the clutch and brake pedals for the switch, and see if anything is broken/loose.

Just in case no one knows how to use CC:
Press button in on stalk - observe green light.
Tap stalk down to set speed.
Tap up or down to adjust set speed.
Pull stalk toward you to cancel.

Must be about 25 mph to work.

Thanks for the suggestions. The car has an auto trans. Also I do not have any check engine light on. Let me clarify - I am not even able to get the green light to come on. Tonight I will do the following and let you know the results: Check the wiring connections at the cruise module, check the switch and connections on the brake pedal, check the fuses, 3rd brake light, fluid level

Just a suggestion, but maybe it is the CC control itself. They are very easy to change, and cost about $55, if you buy it somewhere other that from Toyota. If I recall correctly, it has an AC Delco part number.
(I recently added CC to my 07 CE)

For the owners of 2003-2004 cars, you should have a cruise control cable that connects to the throttle body. It's possible that the cable has broken, or somehow become disconnected from the throttle body (or cruise module).

2005-2008 cars don't have that -- the throttle is Drive-By-Wire (DBW), so there are no cables, and the ECU operates the cruise control through the DBW system.

Let us know, do you hear a click when you press the cruise button? If all of the stuff you checked is ok, it could be something as simple as the button.

i checked all the fuses and they are fine. brake fluid is good also. Does anyone know where the cruise control actuator is located?

if you just bought the car recently I am sure you have warrnaty on it, unless u bought it privately save urself the money and headaches and take it back to where u got it from and tell them to fix it I am sure you and less than 2 weeks grace period

Last night I did the following:

Mechanically checked the brake pedal switch to see if it was operating properly,
checked the third brake light
checked all of the wiring harness at the CC Module
checked brake fluid.
pulled the pedal back while driving ( above 25 MPH) and tried to get the CC green light to come on. - still no good.

I did not check the fuses - which one is for the cruise?
