I've been searching for help for my 98 T100 cruise control without success. Here's the deal: I turn the factory cruise control on, the green "cruise" light on the dashboard lights up, and that is it! No blinking takes place, just a steady green light and no action at all. So, apparently the fuse to the cruise control works. Under the hood, the cable to the thottle looks okay. This system seems to be all electric as there aren't any vaccuum lines attached to it. I can't spend big bucks on this item. Does anyone have suggestions on how to get this working? If not, what aftermarket cruise control is reccomended? I will appreciate any help. Thanks!
Unfortunately I don’t have any data on this car. The system does incorporate various switches for the brake, idle, clutch, cruise control motor, etc. If a switch were to fail, etc, it might prevent the system from engaging. Stop lights work OK? The fuses the system uses may be Gauge, Stop and ECU-1G. But guessing if any of these were blown other systems would not be working.
If you can get your hands on a shop manual, even one for another Toyota model of about the same year you might be able to diagnose the system. The link below is for a Camry, might help.
Thank you toyomoho for your kind assistance. I will study the link you provided me. I have looked at the usual items, i.e. fuses and cables. Not sure I have the expertise to check the emergency brake and brake associated switches. With good data I believe I can. The "cruise" dash light does light up, but that is the only part of it that works. Thanks again for trying to help me.
My guess is a switch, might check the stop light switch. This appears to have two circuits (double pole, double throw). One for brake lights, etc, one that goes directly to the cruise control motor. Also look at the Cig and all the ECU fuses.
I have a 96 T-100. When my cruise control went out, it was the clutch bracket. The clutch bracket (located under the steering column) begins to wear and crack where the clutch cable comes through, causing play in the clutch cable. Because of this, your cruise control sensor does not engage properly. If not repaired, your firewall wil eventually crack from excess pressure.
A new clutch bracket costs about $85. It took me 2.5 hrs to replace in my driveway - only because of cramped working area.
rangechicken, thanks for trying to help me. My truck is an automatic, and I am still at a loss as to why the cruise control doesn't work. Wish it did, bud I can't afford to spend a lot of moolah on the cruise. So, I'm kind of resolved to live without it. That is the only part that does not work on this superb truck. It's my daily ride and weekend workhorse. The T100's are great trucks!
Is there any way you can test the motor/actuator of the cruise control system? I know in my 1985 Celica (vacuum based), the controller was the one that always seemed to die before any other part of the system would.
I haven,t used the cruise for a long time because of the surging. I checked the cable before and found no problems. On Monday , the truck started surging while driving without the cruise. It did it about 4-5 times and didn't do it anymore. The next day it did it again. This time the check engine light came on and stayed on. The truck was running really rough. I continued to drive it for the day because of work. The check engine light went off and the truck ran fine for awhile. It again surged and the check engine light was flashing on and off. It then stayed on and the truck is running rough again. I have not had chance to take it any where to get the code checked
If the CEL is flashing, it means the ECU is detecting a engine problem which has the potential of damaging the Cat. Pull the code to find out which cylinder is misfiring.
When you check the cables, did you disconnected them from both ends? Engine problem can affect the cruise control operation. Toyota cruise control never have much problem with surging, so the engine running problem might have affected its operation.
The cel is now staying on steady. I will pull the code this weekend. I did not disconnect the cables. I will also do that this weekend. I have about 30,000 on my rebuilt motor. The truck has 263,000 on it. The cruise did the surging when I first bought it with 230,000. Thanks for the info N.O.E. I will let you know what I find out. If you think of anything else pass it on.
