Ok , cruise. no engine options stated. so... wild guessing....
on many newer cars, and for sure with FBW or TBW (throttle by wire)
systems, the cruise is canceled any time there are DTCs set.
or any for the throttle portions for SURE.
keep in mind, you are not driving , IT IS.
the PCM is running the throttle no you, you are only begging.
so it assumes the car is out of control if TBW has errors.
and can in fact cause TBW limphome and tranny limp and engine limp home, triple limp. i call it.
it does that so you dont hit objects or others.
see all those lawsuits for toyota lately all for out of control.........?????

so if you had the FSM , in hand you;d already know this.
and would scan the PCM and see if there are any DTCs set.

if all is clean then and only then diagnose CRUISE.

FBW -fly by wire, (generic term)
TBW = Throttle by wire.

the V6 engine may have a throttle cable, so ..... what engine.
what country.


always post engine type and country and if car has throttle by wire
some years, started mid year. so YOU NEED TO KNOW BY LOOKING THAT THE TROTTLE VALVE for 1 second.

Ride height


Toyota state that 10.4 inches is the ground clearance for an '03 Tundra.

I would expect that number is taken from the lowest point of the chassis to the ground. EG gearbox crossmember.

Cruise control on 03 buick rendezvous won't engage, no light, replaced cruise control module?


Your best bet is to check what is happening by looking at cruise control data in the PCM and BCM. You will need a high end scan tool to do this. It could be as simple as a bad switch in the steering wheel or a brake switch that is bad or out of adjustment..

03 chevy z71 cruise contol problem


There are a few things you can try. First, check your
brake lights, if they do not work the problem may be
in the stoplight sw circuit. Also there are 3 fuses you
can check, 1 is a 25amp in the fuse block under the
hood the next 2 are in the fuse block under the dash.
One is the 15amp stoplight fuse and the other is a
10amp turn sig fuse. These fuses are either directly
or indirectly related to the cruise ctrl. Next check the
cruise switchs accel/coast set/resume if either sw.
was sticking in any posistion for 90 seconds or more,
the cruise ctrl. will shut down. There are trouble codes that will set but they won't trip the check engine light. You'll need an obdII scanner to recover
them from the memory. If you don't have one, go to
autozone/napa or advance auto parts they will scan it
free. The codes of interest are po571 stoplight switch
po567 and po568 the cruise ctrl switch's. And any
other codes related to the torque converter clutch -
the speed sensor - throttle actuator control.
Hope this helps. Good luck.

Radio, cigarette lighter, clock display went out on my '03 Toyota tundra. 20 amp radio fuse looks ok. Are there any other fuses I should check out? Thanks. TD


Under the hood there is some. Not sure about your application, but it might control interior stuff too. It will be a bigger amperage than normally inside the car though

MY cruise control on my 03 trailblazer ls works intermittingly


short , loose connection or relay --most likely ---those little green light flicker or come on when generally there is an intermittent short, loose connection or a relay or fuse going to fail soon
and nothing works without a good ground ---one could check if the correct voltage is reaching the cruise contol system and go from there

Just my 2 cents --wiggle the connections --gently ---the cruise control is a complicated sysytem somewhat --you may need another symptom to appear to narrow this down more
but then again --I hate Tow trucks it's a GM --SELL IT Buy a foreign car don't go to ford either

a friend of mine once told me --a 30+yrGM master mechanic that thanks to GM's faulty wiring harnesses and stuff HE will NOT ever want for work and Ford isn't any better --
Get the Toyota if you can that is --unless you are a GM Fan
then sorry my bad no insult intended --

CRUISE CONTROL


My 2003 Ram 1500, would not engage the cruise control, when the speed sensor on the rear axle, was the problem. The other symptoms, speedometer worked irregularly. Replaced speed sensor on top center of rear axle, and problem went away.
