Ford F-150 - 1997-2003 :: Cruise Control - No Coasting When Put On Brakes Slightly To Slow Down
Jul 25, 2016
All, i have an issue ( or at least i think its an issue) with my 99 f150 5.4. When i use my cruise control, i notice when i put on the brakes slightly to slow down, it feels like its not coasting because you can feel the engine still engaged and wont coast. I think this happens even without the cruise on. What this could be? I have the latest update on the cruise control harness. I believe that was for power always to it even in off, causing fires.

RPM's are dropping way off when coasting downhill while towing (as if the motor shut down), CC is on and maintaining desired speed. When at the bottom of the hill, all of a sudden, with a big bang(in the motor) the rpm's have came back up and you drive on down the road as normal. This seems to happen only when towing. "99 F250 7.3 I haven't pulled any codes as of yet. Whats happening?

I have an 02 f150 5.4 and since I got it it hasn't had cruse control. I went to a local ford dealership and they ran the vin and didn't find any recall on it. Under the hood on the master cylinder there is brake fluid coming out of the brake control switch. Would I have to do something with the harness too?

Ok replaced the front brakes, tie rod ends, and all ball joints today. Also flushed old brake fluid and replaced with new. Now my cruise control does not work. Light on the dash momentarily flashes when I try to set the speed. I have checked all the fuses and the connections and everything appears normal.

2000 F 150, 4.2 v6, M5OD-2 Manual Transmission, LX, reg cab .. Cruise Control passed all static and dynamic self test. All fuses inside and under hood checked good and still cruse control will not engage. All other functions work: brake lights, turn signals, etc. Green cruise light is operational, checked pin #10 on wiring harness at servo,amplifier unit under hood and have good ground. The Cruise ON button will not turn on cruise control system and will not light green cruse light.

A few years ago I had the clutch changed on my 1997 F150. Afterwards the cruise control wasn't working. When I brought the truck back to the repair shop I heard the manager tell the mechanic to "attach the clip by the pedal" and that fixed it.
I just had some work done, had to replace the oil pan, and the mechanic had to remove the transmission. Now the cruise control doesn't work. I changed the Pressure switch but it didn't fix the cruise control. What that clip might be that fixed the cruise control last time?

I have an '02 F150 Lariat CC 5.4L. The truck is new to me and neither the cruise control nor the horn works. i have checked all (known) fuses and relays. I have tried the cc diagnostic, and the dash light DOES NOT illuminate. Should I assume that the dash light is not burned out? Is there a way to test the clock spring connections for continuity? and how do I access the connection
i checked the cc brake pressure switch and have continuity there.

I did the diagnosis,on my non working cruise control on my 2000 f250. The cruise light came on when, I, depressed the off switch and turned key on. I depressed on switch,cruise light came on.
I then depressed the resume, coast, and set switch, as described in the diagnostic procedure,suggested,and no light came on. Do the switches for the cruise control are bad.
I have checked the fuses at the power distribution box under the hood and checked the fuses under dash,all are fine. I just replaced the switch at master cylinder, as it was leaking and it had the recall switch replacement, too.

I am stymied by a weird Cruise Control problem on a 2001 F150 Lariat SuperCrew with 5.4L V8 engine that I just purchased. Long story short, the cruise control does not work. That is, when I push the "On" button at any time while the engine is running (even when traveling at highway speed), the dashboard CRUISE light does not come on.
I ran the cruise control "self check" procedure. The first time I ran it, we failed with 3 flashes. So I checked the cutout switch on the brake master cylinder, and it was indeed leaking brake fluid. So I purchased a new switch and cable (Motorcraft SW-6350 Speed Sensor Switch Repair Kit) and installed them.
With the new cutout switch, we seem to pass the self test. That is, after pressing all the buttons in order , I see all the quick flashes of the CRUISE light
(1. On (flash), 2. Resume (flash) 3. Coast (flash), 4. Set/ accel (flash)). Then the accelerator pedal is pulled away from my foot.
However, unfortunately, the cruise control still does not work. That is, when I push the "On' button at any time while the engine is running (even when traveling at highway speed), the dashboard CRUISE light does not come on. What to look at next? I note that horn works, in case that's useful info.

I have a Ford F150, 2003. I replaced the switch above the master brake cylinder just a few months ago soon after I bought the truck. I put 17" rims and new tires on my truck and now my cruise control works intermittently. It worked fine before then.
Can there be a connection between the intermittent failure of the Cruise and the larger rims and tires? I know my speedometer is off by about 4 MPH at 55 but I expected that.

I am having trouble with all sorts of functions on my 2002 F150 4x4, 4wd not working, cluster module illumination not working, horn not working, reving up and down at idle and sometimes dyin, cruise control quit working. I have been reading it is the GEM module that causes these issues. My question is I ordered a new one from Ford, when it arrives I was told I can just install it and It should be pre programmed. but one ford house tells me that they have to install it and program it. Which it right? I have seen several sites on u tube where people replace the module and then start their truck right up without any issue.

I just got into my car with 49k miles and after I left the driveway the check engine light flashed, then went on solid as did the cruise control light. Meanwhile the car was shaking slightly. Its now parked in front of a neighbor's house. I re-tightened the gas cap and turned the car back on after I let it "rest". No improvement. Its shaking even in idle. I'm tempted to take to Autozone to have them read the check engine light code. But I'm afraid of making the problem worse by driving it. I recently got laid off and really didn't expect a car with so few miles to have any issues. Its a 2005 and I barely put 10k miles on it a year. (I'm the second owner and the car is out of warranty).

The cruise switch on my brake master cylinder is bad and causing the cruise to not work. I have it bypassed with a jumper wire and it works fine. is there any reason not to do this?

Symptom: Dynamic Radar Cruise Control (DRCC) fails to slow down the vehicle, (with slowing down or stopped vehicle in front) when DISPlay button on the steering wheel is pressed several times after DRCC is set.
The issue was tested several times with my 2015 GS350 AWD, Canadian model. Maybe it only applies to me, or perhaps it applies to all models with Lexus Dynamic Radar Cruise Control equipped.
Tests: Speed up, turn on main cruise control, and start DRCC when there's no vehicle in front, set to desired cruise speed, set the distance range control to desired range. Now, press the DISPlay button on the handle a few times (5-6, maybe flip through the whole menus, long and short presses. You are all set. Now, drive up to a stopped vehicle or moving vehicle closing to a stop (or slowing down). 4 to 5 out of 10 times, I found out that the DRCC does not sense the vehicle in front, not applying the necessary brake. The screen (where vehicle in front is pictured) shows the vehicle in front at times, other times, The sensing screen is just left blank. Still, the vehicle is on cruise mode and keeps the set speed, however the it acts like a regular cruise control, NOT the dynamic radar one when approaching a slowing down vehicle. At times, pre-collision warning beeps if the vehicle in too close, still no brake. When I says 4 to 5 out of 10 times, the other 5 to 6 out of 10 times, it works beautifully as it is suppsed to. (i.e. slowing the vehicle accordingly)
I tested several times at the 45km/h (30 miles/h), just enough to get the DRCC on, day and night, the vehicle failed to slow down in front of a slowing down vehicle (or a stopped vehicle). At times, the pre-collision warning beeps when the vehicle is at a close distance. I am suspecting that when DISPLAY button is pressed during Dynamic Radar Cruise Control is ON, DRCC fails to work as it should. Not every time, but several times.
I first experienced this at a highway moving at 100km (62 miles) and almost rear ended the vehicle in front if I didn't quicky changed the lane, and warning beep alerted.
I know I shouldn't rely on these technology and I do not, however, if this is a software issue, it should be corrected.
I've been trying to find out when exactly this issue would happen and record on my phone, but I couldn't. I was able to record one occasion on my cell phone, however, it was at night and the vehicle in front was actually a parked vehicle with the rear lights off. (although I think it should've still worked). I am still trying to come up with exact occasion for this issue and get it on video. (Speed/DRCC ON timing/AC/Lights/etc)

I recently changed out the power boost canister for the brakes on a 1990 f-150 2wd. It was successful but now i have no cruise control. I double checked my plugs, all good. I checked my brake lights, all good. brake pedal seems fine and completely raised when not in use. i looked for a fuse and can't find it for that system, seems odd. it's not in fuse jct under dash, can't find a fuse jct under hood, seems odd also. No check engine light has lit.

My cruise light will activate but won't hold speed, it shuts off when I tap the brakes. I did the self test and it went through complete. All buttons worked. After the test it did not show any blinks which according to the chart shows speed control switch faulty, I replaced the switch and does the exact same thing. The recall was also done.

My 1997 Aerostar's cruise control is not working. Horn is functional however. I've checked fuses and they seem to be ok. What could my problem be?

When I had my heads replaced, the mechanic informed me that my cruise control cable was broken. News to me. It worked fine before. He said he couldn't find a replacement. I went to my local Ford parts dept. and they told me it was a discontinued item.
So I went online and ordered one from Direct Ford Parts and it did not match. The part number was FMC-F49Z9A825JA. In the parts catalog it says it fits 92-97. Not even close. The one I have has a screw off top and the one sent has a bolt on housing.

I was coasting down a steep hill yesterday when the CEL came on. I pulled the code this morning and got code P0174, system too lean bank 2.
I cleared the code. Should I just wait to see if it happens again? The truck is running great. There is no sign of a problem. BTW, it's 99 F150 5.4.

I have a 2002 Ford F150. 273,000 miles on it. When I am going about 50 mph and I start down a hill and let off the gas a bit and then when at the base of the hill I push on the gas to accelerate then sometimes it does a weird hesitation or slight "lurch" but it is NOT in the engine. The engine continues to run smoothly during this lurch. It only happens between 45 and 55 mph. It only seems to happen when I am trying to accelerate out of a coast. I had the dealer check underneath thinking it might be a u-joingt? They said everything underneath seems to be in good shape. Someone told me to consider Ring and Pinion Slop problem in the rear differential? When I read about that it seems that it normally makes a noise. There is no noise with my truck's problem.
