Ford F-150 - 1997-2003 :: ABS Light Comes On And Off At Random - Code C1185
Apr 21, 2015
My abs light comes on with the code above and im looking to fix it. No I don't want to buy a new abs module. Code C1185 - Car Forums and Automotive Chat the only thing i could find remotely close is from this link for a 2000 ford windstar. Need to just comfirm that there is a chance that resoldering the joints would work in fixing the problem that would be great. The light comes on and off at random. 2001 f-150 lariat 4x4.

I have a 03 F150 with a bi-fuel 5.4 engine an it has 195000 miles. I have had trouble for some time now with misfires. I bought the truck in october of 2011 with 125000 miles and replaced all the coils and spark plugs because it was misfiring badly will running on CNG. It was fine on gasoline and never had any codes. After I replaced the plugs and coils it ran fine on CNG and gasoline.
This summer 2013 it began missing badly at highway speeds only when running on CNG. If I accelerated the miss would go away until I was light on the throttle again.I checked the misfire count and found the bad cylinder and replaced a coil. Then a day later same thing on another cylinder. I swapped a coil from another cylinder and problem went away for a day. Eventually I chased the misfire around all the cylinders on the engine until I had ended up either replacing a spark plug or swapping a coil on all the cylinders. And I still had a misfire. It seemed to be worse on days with temperatures above 90 degrees. Eventually I got it to stop misfiring.
So now 5 months later I am back again with a misfire. This time it is misfiring on both gasoline and CNG and under any throttle conditions, except coasting. I have no codes. And the misfire monitor is sending me around the engine again. I have replaced a spark plug in two cylinders and swapped 4 coils.
I'm ready to buy all new coils, but I want to be sure that it is not a waste of money since the old ones only have 70000 miles on them.
Two days ago I had the misfire monitor saying #4 in the evening and the next day without me having done any work on it it was saying #6. Later that same day it said #7 and I still hadn't done anything other than drive the truck.
I checked the connections at the firewall on the drivers side with the three large plugs that are held in with a 10mm bolt, they looked fine, no corrosion or burnt pins. I checked the connection at the ACFM which also looks good. I will check the connection at the PCM in the next day or so.
Some other problems that may be contributing:
1. I occasionally get a U1262 code (scp fault)
2. Sometimes when I check the misfire monitor it only shows 7 cylinders, sometime 9 cylinders. I am using an Innova 3160 scanner.
3. I have either a leaking valve cover gasket or leaking head gasket, because I have oil dripping from the rear bottom corner of the passenger side cylinder head right above the exhaust pipe.

I was involved in a light accident over the weekend. I was hit in the rear by a Prius which didn't do body damage except for the 7 blade harness for my trailer towing. But, now the truck has a random misfire code. You can feel the truck jerk when you go up any grade. We changed the fuel filter and dumped in some cleaner already. One guy says its fuel and one thinks its coils. It is a 2003 F150 extended cab 5.4 with a nearly new motor. The truck has about 175xxx on it and I have had it for about 40xxx. I have not changed coils. We did check the inertia switch on the passenger side and it was not tripped.

I have got the most aggravating electrical gremlin possible. For over a year now, the truck intermittently just dies. Mostly it happens about 2-3 mins after start (every couple weeks or so), then takes a couple of key offs, then back ons to restart. But it does restart and then runs fine for a time.... 2 weeks ago I was rollin' down the road and hit a pothole, and whammo, she died, and wouldn't restart. I thought, "great it was the intertia cut-off going bad." I had it towed to the shop where they did some diagnosis and told me it threw a PO231 code.
The tech then said he was doing the diagnostic manual directed test, and swapped out the fuel pump relay, and it started right up. New relay, out the door. A few days later on the way to work about 2 - 3 minutes after start, she dies again. I hang my head, say a curse word, and key it a couple times, and it starts back up and runs fine. Presently speaking she's back at the shop, but the owner, who's a straight up dude was loath to take her back, because it was running fine at the time.... I've got to figure this thing out before I drive it off a cliff.
Truck -- 2001 7700 XLT 5.4L 88K miles
Symptoms -- Random interval engine stops with short delay to restart, 1 hard bump engine stop with no restart. PO231 code (after the hard bump no restart). Didn't check it previously (wasn't aware there were "soft" codes).
Troubleshooting to date -- 1 new fuel pump, 1 new fuel pump relay.
Only things left are the inertia cut-off switch (which apparently don't go bad that often), and the wiring itself/connections to the different components....

Just today my ABS light came on and the AE showed DTC C1185 (ABS power relay output circuit failure). I have checked my fuses and all looks good. New batteries in truck a week ago. The manual is advising to do a few pin point tests on the EHCU. From what I can tell, it looks like I would have to remove the hydraulic control unit just to do the pin point test. Obviously that means a bit of a mess with the brake lines being disconnected. If I have to get that deep into the truck disconnecting lines and making a mess, I want to have the new part available so it will be a quick fix. Can I keep driving the truck with that light on? Will it cause any issues or just problems if I have to slam on the brakes resulting in no ABS.

The "service engine soon" light on my 2003 F150 Supercrew 4.6L (225k miles) just came on. The code it's throwing is P0171.

The Service Engine Soon light is on in my 2001 F-150. I checked the code and got PO156 generic O2; circuit (bank 2, sensor 2). What are the most common things I should look at? The truck appears to be running fine, no driveability issues.

It is a 1997 Ford f150 5.4 4x4 extended cab 175k miles. Took a 600 mile trip, first 300 no problems, then the "od" light began flashing, the truck shifted fine so I kept going, drove for about a 100 miles then stopped for fuel and read the code, (p1728) cleared the code and drove another 200 miles, no light no problem. The whole time there was no drivability issues. Yesterday I drove all over town, stop and go traffic, locking the TC and it would also unlock, no problems all day, drivability was fine. What to do?
1. Just keep driving it?
2. Does changing fluid fix this problem?
3. Rebuild the trans, because this was just the first notice.
4. Sell it quick no light and drives fine.?

My Service Engine Soon light came on early last week and I got the code P0442- Evaporative Emission: System leak detected (small leak).
What are the most probable things I should look at?

To start I was driving to work tonight and noticed the o/d "off" light flashing. it shifted hard one time then felt normal the rest of the way to work. At red lights the o/d light world turn off and about 3 minutes later it would flash again. When I got to work, I checked my code reader which gave me the p0705. I have searched around the net for about an hour and one thing i am seeing is that the fluid is "hot" or that there isn't enough. i have checked it and it looks slightly low like right above the add indication.
The only sound I here from under the truck is a rattle when in drive and at idle, but once I give it some gas it goes away. On they way home that night the o/d light was still flashing but it drove fine just at higher rpm, it down shifted hard one time but there were no other issues. I checked the fuses and they are all good.

My amber ABS dash light in my 2003 F150 came on the other day. I changed out the rear pumpkin sensor, ohmed the front wheel sensors (they were within specs posted in FTE forum) and changed out the master cylinder pressure switch under the hood (my left/rear bulb was burnt out around the same time the ABS light came on). After doing all this the light remains....so I had the ABS code read and mechanic advises code C1206 was present. He recommended replacing the "dump valve on the frame rail". He also advised this is a very expensive fix so I might just want to live with the light being on all the time. What should my next steps be to get rid of the ABS light and get my ABS system working properly?

2000 F-150 Triton V-8, Super Cab, 2WD, ~170,000 miles, 4-wheel ABS (one speed sensor on each front wheel and one on the rear differential). The ABS light comes on a few minutes after driving. It seems to take a little bit longer for the light to come on when the weather is colder.
I used a Cen-Tech 60794 OBD II/CAN with ABS scan tool with key on, engine off, and the below sequence. No codes were detected. I then left the scanner connected but powered off and drove around until the ABS light came on. Pulled into a parking lot with engine running, powered up the scan tool and went through the following menu choices:
Diagnostics
ABS
Area - USA vehicles
Model - Ford
Although the tool's instruction manual has several more items that may or may not be required (VIN digits, model year, etc), the next thing I saw is a message indicating the scanner is linking with the vehicle computer. During that time the ABS light went out. Next on the scan tool display my choice was to read codes or erase codes. I selected "Read codes" and the display said there are no codes in the module.

Looking to see how to repair my blinking light. Code reads a 27, most what I've read says it's a PAD light, which this truck does not have. It has been in an accident, both airbags deployed. Since then both seat belts & bags have been replaced, nothing else.

I had recently thrown a code for a 'misfire detection monitor disabled' , never did address the issue. But just the other day the service engine light went off, the light had been on all this time and now it's off. My question is, how do I know if the light is just burned out. Is there something safe I could do to make the light come back on just to see if the light is actually still works.

Last week my service engine light came on. Friend checked it with his code reader. Got a P0402 code insufficient flow EGR valve. I have read several different threads on this subject on another Ford truck forum, slightly confusing me. Should I trust the code and just replace the EGR valve or do a number of other things that
1. Clean the throttle body first?
2. Test the EGR valve by blanking it off?
3. Test the DPFE valve?
4. Replace the DPFE valve instead of the ERG valve since the EGR valve rarely goes bad?
5. Only get OEM parts since after market parts do not last?

I was driving along today and my Check Engine light came on. I stopped at the nearest Advance Auto to have them pull the code and it came up with the P0420, Catalyst Efficiency Below Threshold (Bank 1). I asked what could cause this and they mentioned that the fuel that was put in could be causing it. They didn't mention any other possible causes. Any others? I'm thinking it could be the fuel because the last gas station that I stopped at and filled up at is one that I never go to, and maybe just got a bad batch of fuel.

I have a 1997 F-150 2WD 4.6L V-8 that began having random misfires as I would drive. I was planning on going out today to get the new plugs and coils however when I got off work and pulled into my drive something happened when I went to leave the truck wouldn't even crank it just made a clicking noise. The battery has full power (the radio ect. still works). I am hoping that the problem is with the coils and plugs but if not ...

I have a 97 f150 (built 96 as 97 model), 4.2l 4x4, auto tranny. Here's the problem, when I turn my key forward to run position my starter kicks on and starts the truck, and stays engaged. I have a constant 14v at the signal wire on the starter relay (yellow red stripe). Also tranny started to slip, od light flashing. I replaced ignition lock cylinder, ignition/ starter switch, starter relay, starter, and today transmission range sensor (neutral safety switch 8 pin), same problem. Cel code that I had 2 days ago was P0707 tr sensor low input.
