I am having trouble with my 2000 Excursion 7.3. It died on my wife this morning, but it started right back up and made it home(4 miles). Figured it was the CPS but when i went to hook up the code reader, it just kept saying that i needed to connect it to the vehicle first. I verified that the reader was working on both my other vehicles. Then had to go to work. I wondering if my ECM is going bad?
View 8 Replies2007 Ford explorer 4x4 V8, U0101 Failure to communicate with the TCM
Vehicle shifts very hard when under load then and when the Traction control light and the "wrench" light come on it seems to be stuck in high gear, if I stop it takes off like in high gear and never shifts, when I do an ignition cycle then the lights go off and it takes off in first gear and shifts as normal unless it's under load it will bang in and out of gear. Where is the TCM located? On a side note I do hear air like vacuum behind the center console when I press the pedal. Not sure if it has always done this or not.
Compressor won't engage and cool. Mechanic checked system and said ac control head is bad and it cost like 800.00. But when I go and search the part they are like 150-200... Did I miss understand what part is called. He said he checked the compressor with a scanner and the compressor will not communicate with the head... said he thinks compressor shorted out the head. He also jumped the compressor but it still would not work.. Any clue what part I should look for?
View 5 RepliesTruck had a rich on bank 2 code about a month ago, I cleared it and the service engine light stayed off for quite some time.
Last friday on the way home from work the truck started shaking badly right from idle, and at one point on the freeway the service engine started flashing. I couldn't pull over as I was on a bridge but once I dropped my speed the light stayed on but the flashing stopped.
I went to plug the truck in today and first shot it didn't communicate with the code reader at all, I talked to someone who told me that the cigerette lighter fuse is also the OBD port fuse, I pulled a fuse from somewhere else and plugged the reader in again. This time it started communicating with the truck but didn't display any codes while all the while the truck is miss firing and the service engine light is lit up on the dash.
One other weird thing: The fuse had an LED indicator to show that it is blown, when I push the cig lighter in the led gets a hell of a lot brighter, if there is always power drawn through the circuit shouldn't the LED be constantly bright all the time? I'm wondering if there is a short somewhere. Where to look next??
I am trying to run some diagnostics and get codes for my truck. Problem is the scanner won't communicate with the trucks computer. It's the usb elm 327connector and Iam using the forscan program.
Changed to ciggar lighter fuse. still not working. I think the previous owner had a edge program in it idk if that might of fried the pcm or is causing it not to read right? Do I need a better connector or are the pins inside the trucks communicater bad ?
Title says it, I just installed my Hydra Chip, now my edge says it cant communicate with PCM. I have checked all the connections on the edge, all is good. I planned on just using the Edge only for gauges. Will it not work anymore now that I have a Hydra? If not I will just sell it and buy an Edge Insight, so long as that will work.
I think its the Edge EVO 2, its this one.
I have a 2003 Saturn Vue that will start and run then die after 2 seconds or so. I thought we needed to reset the security, but the Security light never comes on. I get both the service and the service with a wrench. I put it on a computer and we get the U2107 code. Can a weak battery be the culprit? I cleared the code and it started then as soon as I turn it off, the code is back and it starts then dies. I'm told that it needs a BCM, but the code indicates that the BCM cannot communicate with the ECM.
View 1 RepliesI went to a local toyota today to have the brake fluid changed and their scantool couldn't communicate with the car.
Now, I wanted to ask a few questions.
1) Is there a separate communication ecu that handles the diagnostics port?
2) Is there a fuse that could have been broken?
To give a few more details, the car is a 2004 gen II prius. It has an lpg system installed. The lpg ecu reads the fuel trims through the diagnostics port all the time.
I have a 2002 VW Passat that I cannot communicate with the ECU. I have the latest version of the Vagcom software downloaded. It has the factory radio installed and still will not communicate. The car runs, but runs rough. Anything else to check?
View 5 RepliesI recently put my stock 18's with TPMS. After 200 miles the car is still refusing to communicate with the TPMS, I still got the low pressure light and all 4 sides show no data. I tried resetting sensors by holding the TPMS button, but nothing is happening. Not sure what happened ?
View 5 RepliesWhat is involved in fixing TCM system and ECM (I could not start my '04 Phaeton, had it towed twice, only to find I needed a switch, frame, and a mechanism [shifter]).
Now I notice the center vent door that goes over the clock has two cracks in it and I also noticed some other scratches on the so-called wood area on the console. What is a TCM, and an ECM, and what would have to be removed to replace brake switch, PRNDL sensor, and shifter mechanism? Before work was done, service writer said the steering column and the center console would have to be removed. I know when I go back to the dealer Monday (2.8.10) there will probably be denial, so I would just like to know in advance what had to be removed.
Having fitted a 9W7 - 7P6 035 730 C bluetooth module to my 2009 Passat recently, to replaced the old basic nokia universal car kit system. Everything works except I can't operate/control any of the phone menu which display on my white MFD screen, the "phone" button, "OK" button, "arrow up" button, and the "arrow down" does not want to communicate with the bluetooth module. I have a 8 buttons multi function steering wheel. all function in rns510 are working(address book,call history,etc...)
View 4 RepliesSo, the very first time it happened was the weekend after I installed my new motor mounts I am not sure if it is a coincidence or if there was something that I touched while installing that is causing the car to act this way. So I notice that it's more common on the wet days even though I have started to doubt this recently as well. The instrument cluster illuminates CEL and EPC for a brief second and the car feels like it looses all power and sometimes even stalls when at idle but then after that goes away it runs like a champ. Also ever since this started happening the car is really hard to start after it sits off for few minutes when at normal running temperature. Right, when it happened I tried to scan it and I thought it was the scanner that was not able to communicate with it but that wasn't it since I have tried over 10 different kinds now( that includes the ones that have scanned my car with no problem before). I did have the CEL to stay on once but I still couldn't scan it and it went away by itself or I have reset it by disconnecting the battery. Its really driving me crazy and I am stuck but not giving up on this car, I love it too much and it's been very faithful to me so far! I mean there was literally two days recently when the weather was dry when I drove the thing without the random occurrence of EPC and CEL but it still didn't want to start when warm. In fact, one time after work after it has been sunny all day it didn't want to start when the engine was still cold as well.
The things I have replaced or tried so far that have not repaired it are:
*New Camshaft Sensor
*New Crankshaft Position Sensor
*New Purge Valve
*New Coil Pack
*Took off and cleaned my Throttle Body
*Checked with and OHM meter as many grounds as i could find between battery and they all checked good(the main engine ground looks good)
*Cleaned MAF sensor
*New Coolant Temperature Sensor
*Checked that all fuses were good and seated
*Verified that the k-line is good.
*Able to scan the ABS module and radio through vag com so i know its something with the ECU communication
That's all that I can remember as of now. the car went through many stages but here is how it looks as of now.

I just put new plugs in and changed the fuel filter. I also hooked it up to a ecm reader to see if there where any faults and it does not have any. I reset the computer just he same. But for some reason I can't get it going over 30 mph and when i floor it. It just doesn't go anywhere. At first it did read faults in the 6 plug but I didn't have a check engine light on i just replaced the coil and plug but now after I did everything I cant get above 30 and its scary. I just don't know what to do?
It does idle normally. As for the fuel pressure i took the filter off and turned it over and fuel runs through fine from the tank. I checked the wiring and it looks ok. No codes are present. This just started it happened a long time ago but after I changed the fuel filter it worked fine so I changed it again thinking it was the problem again but after i did it the problem still persists. I don't have any check engine light on either....
I am having a hard time figuring out what is going on with my A/C. First time you start it for the day, works great, blows cold air, but will only do it for about five minutes, then the compressor kicks off.
I have tried by-passing the high and low pressure switches, compressor still will not kick on. Checked the air-gap, it is fine, and I actually removed the shim, so there is almost no gap at all now, didn't fix the problem.
I tried replacing the A/C clutch relay, no luck there. I can tell you that if I manually push the contact in on the A/C clutch relay, the compressor kicks in and runs.
The only thing I can think of at this point is the A/C control panel in the dash, but wanted to check before I buy that expensive part and replace.
If it matters, this is on a 2000 Excursion, with the 6.8l v-10
I have a 2000 excursion v10 with 66k miles on it. This past weekend i went to engage my 4wd and it would not work. the light on the dash is on and i think i heard a click but no luck. A buddy told me to tap the transfer case motor with a hammer but am a little skeptical. another friend told me to check the vacuum switch with the vent/ defroster but i am not sure that holds true with my yr/model (i did a test where i left the vent setting on face/feet then turned on the 4wd. the airflow seemed to remain as set). About a year ago i removed, regreased and repacked my front hubs.
View 10 RepliesI've had a lot of problems with this truck and strongly believe the pcm is bad so i bought a used one now it wont start. Just to let you know i did put old one back in to see if it did run with it and it did. I spoke to the dealer they say I have to bring it in to program it for the PATS. I know its got to be programed but does it have to be the dealer.
View 10 Repliesmy 2000 Ex has a 6.8 and it overheats when the ac is on and anything over 60mph, im not loosing coolant, is the clutch for the fan shot??
View 14 RepliesMy speedometer is off by around 5mph. When I'm going about 65mph it only reads about 60mph.
How is this corrected? Programming or speedometer cable gear?
I have an intermittent problem with my 2000 Ex V10 with factory remote start. Sometimes when I put the key in to start the truck, I get nothing. I believe the theft light flashes but I am not entirely sure. Sometimes after a few tries with turning the key it will start. If I hit the button for the factory remote start it always starts, so I have never gotten stuck anywhere.
This issue could happen 2 or 3 times in a row and then not happen again for days or weeks. It's been going on for a couple of years now. What to look at. There is no telling when it will happen again though.
BTW, I have stomped the brake pedal and I have moved the gear shift when it happens and sometimes on retry it starts and sometimes it does not. When I just keep trying the key sometimes it eventually starts too, so I do not think it is the safety in the brake pedal or in the shifter, but I could be wrong.
can i get some tips on to fix the flexplate on a 2000 ford Excursion.
Here is the details:
2000 Ford Excursion
110,000 Miles
V10
4x4
I am positive that the flexplate is bad. My friend and I are planning on doing this on saturday.
