Ford F-150 (2004-2008) :: Compressor Will Not Communicate With AC Control Head?

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?

Saturn - Vue :: BCM Cannot Communicate With ECM

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.

Ford Excursion :: 2000 - Can't Communicate With ECM

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?

Phaeton :: TCM / ECM Don't Communicate - Center Vent Door Cracked

What 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.

I have a 8 buttons multi function steering wheel. all function in rns510 are working(address book,call history,etc...)

Ford - Explorer :: Code U0101 - Failure To Communicate With TCM

2007 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.

Golf IV / Jetta IV :: Random EPC And CEL - Can't Communicate With ECU - Doesn't Start When Warm

So, 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.

Ford F-150 - 1997-2003 :: Truck Won't Communicate With Code Reader

Truck 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??

Ford 7.3L Power Stroke (1999-2003) :: Scanner Won't Communicate With Computer

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 ?

Ford 7.3L Power Stroke (1999-2003) :: Hydra Chip Installed - Cannot Communicate With PCM?

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.

Prius (2004-09) :: 2004 - Driver Side Brake Led Stopped Working

Prius 2004 with 86K miles. My brake led light on the driver side stopped working completely the other day. For some time now (6 months) i knew the top led of the brake light was not working, but yesterday I discovered that the whole led is failing. tail and parking light on the same assembly are working fine. I pulled off the plastic door inside the trunk and I checked connections for faulty ones but everything was tight in its place. Is there anything else I can do before preparing to go to the "butcher" dealer?

Prius (2004-09) :: 2004 - Red Triangle Came On After Changing 12V Battery

I have a 2004 Prius, the Red triangle came on intermittently and went off so I changed the 12V battery last night, after changing it the red warning light went off and everything seemed okay. Today while driving, the warning light came back on. I checked the battery voltage via diagnostic mode on the cars computer and the specs are what they should be. I noticed the following error codes in the computer:

01-D5, Sub-code: 190-30-8
01-DC, Sub-code: 190-B7-8
01-DC, Sub-code: 1C6-4D-F

Not sure if these are what is causing the problem.

Prius (2004-09) :: Only Getting 24.9 MPG?

I just got my Prius and made the test drive around the city. On my consumption screen, within 19 miles, I get only 24.9 MPG.

Does this normal for short distance driving? I heard some people got 40+ MPG or 50+ MPG.

Do I have to make longer drive in order to see the impact?

Prius (Gen 2) Fuel :: 2004 - MFD Went Out

I have a 2004 prius and my MFD recently went out. So I decided to go looking for a good MPG app for my iphone since I could no longer use the car's built in feature.

I really don't like the native apps that just keep the data confined to the phone and I find emailing my data around and having to do things in a spreadsheet to be painful.

I want my data all online, but the app to be native, so it's snappy and responsive.
