Wasup guys..........

I've been putting this off but I finally want to fix this. When I turn on the cruise control from the main switch on the dash and then try to activate it at a certain speed, it doesn't hold. The green light on the switch doesn't work anymore so I cannot tell if the system is turning on or not. I can't find the ASCD fuse. My Chilton's manual only shows where the ASCD clutch, hold, and inhibitor relays are. I haven't checked them yet as I wanted to start at the most obvious place which is the main fuse. Does anyone know where this fuse is located? Any other tips or suggestions are welcome.

Thanks.

 

i think this happened to me be4.. i was driving down to NC from NJ and the Ccontrol worked fine until mid way... i just kept banging on random things.. and played wit switches here and there... and finalyl it worked again.. just mess around wit the switched.. it should turn back on like mine did..

 

Yea but doing so could induce a short in the switch. There are tiny pins inside the switch that can easily break and all it needs is a hot wire to touch the ground wire and you have a short.

I will do some testing tonight with a light tester, maybe it's the switch itself.

 

What did you find?? I have the same problem and really suspect the control unit on the steering wheel...it gets the most "push-n-play" and pin/contacts are easy villans! I think there is a continuity test in the Haynes 4th generation manual that shows pin continuity test. Please let all of us 4th gen.s know what you find...this IS a common problem to all of us!! Thanks! Doug

 

Mine isn't working also but i don't use it so i don't care, but the my ASCD fuse is in the fuse box by the washer fluid canister.

 

mine is ****ed up as well the light just blinks when i try to activate it.. im gonna see what is up with it in the morining ill report back with my findings..

 

Pull the slot out and make sure the connector is tight. and check to see if you have a tailight out. The fuse is #12 - 7.5A

 

See, I told ya'll this was a common malady! Seems one repair points at ASCD fuse on drivers side of engine bay...other points to problem (contacts?) in black housing on steering wheel. PLEASE post your actual results/fix so we can all get going on this thing and maybe make it a part of a "stickie" for all members to refer to. Results!!!! Thanks, Doug

edited response: My( and many .org'rs) cruise control switch lights up on the dash but never makes actual engagement (never get "cruise" indication in instrument panel)! signal going from dash (even though lit) to cruise pod on steering wheel (resume/engage contacts not functioning) or ASCD relay/fuse not activating control module on firewall/speed sensor/throttle control???? I still suspect the steering wheel control pod contacts...thanks for input on actual problems found and fixed!

 

he said the light on the switch doesnt come on.. so if theres no power to that switch the steering wheel controls will not work at all.

 

Actually, the main switch was working for a while eventhough the green light on it wasn't coming on. I haven't checked into this because I had so much stuff going on last weekend. I will make some time this weekend and check the switch and the fuse. 99se5speed, I could have sworn that the ASCD fuse in the fuse box by the washer fluid canister is actually a relay but I'll check again.

 

mine did this a couple weeks back and somehow it just started working again.....been fine ever since. gl to you guys w/ this issue..

 

my CC has never worked. the light turns green on the switch but it never cruises when i press the buttons on the stearing wheel. $10 for a solution

 

Anybody check the speed sensor behind the instrument panel (cluster)?

 

i figured it out fellas.... if the light blinks then CHECK UR PUMP!!! now my problem was that the cc would work sometimes.. mostly not though.. so since i have the fsm i checked all the things that could be wrong.. then i got to the pump... i pulled it out and wired it directly to the battery.. it made the pumping sound but the actuator didnt move!!!! so i took the hose off and put a vaccume pump to it ( by passing the cc pump of course) and the actuator moves!!!! Then i took and tested the pressure coming out of the cc pump and there wasnt any!!!! PROBLEM SOLVED im going to the junk yard for a new pump....

 

I hope that in my case, its not the pump. I still think that the main CC switch is the culprit.

 

My light doesn't blink unless I try the pushing steering wheel button while holding the dash control on... My dash light stays green "on" when engaged but steering wheel control never lights up the instrument panel "cruise" (cruise control never activates). DR , I hope you try the contact continuity test for the steering wheel pod and report back! I believe that's where it is, too!

 

alright guys... when u press the switch to ARM the cc.. it turns green... when ur above 30mph and press cruise.. the light on the dash is supposed to come on.. if it doesnt come on right away and it blinks.. check ur pump like i said..

if the ARM light doesnt come on then u have to check ur fuse and the relay.. thats a little more complicated..


i just replaced the pump for 20 bucks.. it works great now...

 

Do you happen to know where the main fuse is because I couldn't find it, I did found the relay and I have yet to test it.

Also, my fog lamp went out as well and I've already checked the fuse for that, its good. So I'm assuming that something is up with the fog relay or the bulbs but it's coincidental that both fog lamp bulbs went out at the same time.

 

Ok...I checked the main CC switch, the one located on the dash (not on the steering wheel). There's definitely no juice going into the switch. I still can't locate the ASCD fuse. There is no ASCD fuse inside the engine compartment, only the clutch (by passengerside strut tower) and ASCD relays (infront of the battery) can be found.

I was hoping that I can pull some codes related to the ASCD from the ECU but all I got was 05/05 (No Failure Recorded/Detected).

So as of now, I'm totaly stumped here.

 

Man! Are we all chasing the "magic" fix or what ?? My guess on the pod connectivity sounds like it got shot down...will need to check my own if "magic" isn't found. f550maranello; Please post back to us when you actually install new/used pump= results (hopefully "the thing!") and we can all go to that with sense of certainty. If this DOES prove to be the/a common culprit then lets get a part # listed in the stickies!! Waiting to hear what y'all find!! Doug

 

He already did, check post #17. f550maranello's issue is a little different from mine. His CC arms as indicated by a green light that lights up when he turns it on. Then when he pushes the SET button on the steering wheel at a desired speed above 30mph, the CC light on the instrument panel, either doesn't come on right away or flashes....that's a sign that the pump is going bad which is evident in his case.

The issue I'm having is different, the main CC switch just won't turn on. I was hoping that the switch is bad and that I will get a 12v reading on one of the 6 pins behind the switch but I didn't get anything. So this tells me that either the fuse is bad or the main ASCD unit is bad. Since I can't find the main fuse, I'm going to assume that the ASCD unit is probably dead. I can't see a bad clutch switch or relay affecting the system's ability to arm as it should only need 12v to do so. I have googled all possible fixes and the search results seem to point to a bad ASCD unit. Unless someone here can point me to the exact location of the main fuse, which I really doubt exists, I'm going to start looking for an ASCD unit at the junk yard.

 

I had some time to troubleshoot my CC issue so more today, even fixed the problem with my fog lamps (grounding issue).

The last time I checked the main CC switch, I must have gotten bad ground. This evening, the main switch worked just fine. Now I'm starting to think that maybe the pump is bad. I took the car for a drive on the freeway, the CC armed but when I pressed the SET button on the steering wheel, nothing...the CC light didn't come on at all.

f550maranello2, perhaps you could help me out a little and provide some troubleshooting specs. I'm more interested in what you did with the pump to test it. Please provide some specifics so that I can test this pump this weekend.

 

mines weird as well, sometimes it works, sometimes I won't... what do u do about it?

 

Thanks DR...I guess I missed the "holy grail" fix = "pump" Does anyone have specific name of pump and/or part #...so we can all start wrenching, cursing and (hopefully) cruise controlling! Thanks for all the great input guys...we got several apparent leads to same (I hope) problem and potential fix!! Doug

 

i think you might want to check your main ground points from the battery (-) terminal.. seems like your getting alot of grounding probs.. thus leading to these elecronic troubles....

 

I should clarify some things:

My fogs are aftermarket, each lamp is grounded onto the metal beam behind the bumper cover. I'm not sure why the ground suddenly stopped working but it seems like grounding higher up which is less susceptible to the elements did the trick. I grounded the fog at the same ground point where the hood sensor, for the factory security system, is.

As for the bad ground when I was testing the main CC switch, I was using a light tester to see if the switch is even getting 12v, when the ignition switch is in the ON position. I grounded the light tester on the door hinge but turns out that it's a bad place to ground anything because of the paint. I found bare metal behind the driverside fuse panel. And that's when I realized that the main switch is still operational.
