This might be of some help :

No You can only get this P code if you have auto transmission and the speed sensor is bad or failing on the transmission tail housing. A trouble code is an alphanumeric value that corresponds to a particular type of fault. The list was originally created by the Society of Automotive Engineers (SAE) for use by all vehicle manufacturers who have to comply with OBD II emissions regulations in the U.S. The same list of basic codes have also been adopted by European and Asian auto makers. The list of trouble codes is subdivided into four basic categories: Powertrain ("P") codes (engine, transmission and emissions systems) Body ("B") codes (Climate control system, lighting, airbags, etc.) Chassis ("C") codes (antilock brake system, electronic suspension and steering systems) Network Communications ("U") codes (network wiring bus and modules) I'm going to say NO on this one also, more than likely something wrong with the ABS pump if anything. I'm so busy I wish I could help you but with my current full-time job I am having some trouble balancing my family life-work life.

MOSFET is a type of (Metal–Oxide–Semiconductor Field-Effect Transistor). Ok, here's what my digging around the web discovered. The orginal MOSFET #V30114 appears" to be a Siliconix product. The V30114 would be their in-house part number and I did find various "Oriental" sources that carry a Siliconix item part # V30114-T1 (but no "english" description of what it's!) Now comes the fun part !! In 1998 Siliconix was acquired by Vishay (www.vishay.com) and they completely renumbered and relabeled all the products! Vishay has grown through acquisitions to include such top names as Dale, Sfernice, Draloric, Sprague, Vitramon, Siliconix, General Semiconductor, BCcomponents, and Beyschlag. The Vishay web page shows their Vishay-Siliconix part line includes Power ICs MOSFETs small signal FETs Analog switches and multiplexers obviously we can eliminate analog switches and multiplexers but doesn't provide any sort of cross-reference from the old to new part #s!! I took a little scroll thru their on-line product catalog for each of the other categories and here is my best guess for the original mosfet: Vishay Siliconix SUP/SUB75N06-07L N-Channel 60-V (D-S) 175 °C MOSFET Datasheets: http://www.vishay.com/docs/70776/sup75n06.pdf ABSOLUTE MAXIMUM RATINGS Continuous Drain Current @25 C 75A Continuous Drain Current @125 C 55A Pulsed Drain Current 240A Operating Junction and Storage Temperature Range -55 to 175 °C Gate Threshold Voltage MIN 1V, MAX 3V The power mosfet I used as a replacement: International Rectifier IRL2505S HEXFET POWER MOSFET Datasheets: http://www.infineon.com/dgdl/irl2505spbf.pdf?fileId=5546d462533600a40153565b75022502 ABSOLUTE MAXIMUM RATINGS Continuous Drain Current @25 C 104A Continuous Drain Current @125 C 74A Pulsed Drain Current 360A Operating Junction and Storage Temperature Range -55 to 175 °C Gate Threshold Voltage MIN 1V, MAX 2V Perhaps I'm only doing my best guess here

Maybe they use wrong transistor for the job ? The original transistor has a custom number you can't find datasheet so you can only do best guess. I used IRL25055PBF so far no issues it's been only few years Not the best picture quality, the red and green wire were used to dump the eprom memory.

I honestly don't know how they can fix these things so cheap, factoring in the cost of labor and parts. If i was fixing it professionally I would have to charge at least $200. Just to fix the issue you have to remove the black connector (the transistor is right under the black connector) to do that you have to remove the main board completely out which pretty much means you have to desolder all the connectors. Perhaps they are doing some mumbo-jumbo black magic

My suggestion is to find salvage yard that you can pull parts yourself. NOTE: This is sort of a hack only good for testing the ABS pump. I bet you will not find the ABS module for the truck but at least you can salvage one from Dodge Durango, Dodge Dakota or even Ram Van. This of course will sort of work but it will throw a code after about a minute (CODE 84 - VIN number mismatch). Warning the ABS will not work correctly in the event of emergency braking (wrong programming for the weight of the vehicle). Unfortunately the VIN is program in PROM One-Time Programmable memory Inside the Intel 8051 microcontroller, basically you can't reprogram the VIN number. Other issues will be the speedometer will be way off, wrong axle tone ring tooth count and tire revolutions per mile programming, this can be reprogrammed with a proper scan tool. I'm not sure where you're located, for example by me in Pennsylvania you can go to Harry’s U Pull It. link http://www.wegotused.com/home-2/ What makes Harry’s different from other businesses, and from other “junkyards”, is that customers, who pay a $2 entrance fee, locate and extract the part by themselves. They then pay a minimal fee for each part when leaving.

Kelsey-Hayes 325 EBC; All wheel ABS system: If ABS pump runs continuously even with ignition key off, the culprit is an electronic control module, which uses a transistor to switch the pump on and off, rather than a relay. simply unplugged the 2 pin connector at the pump, until the ABS can be repaired.

No. I'm not sure what the issue is but that's definitely not the tone ring. Trust me I fix this issue back in 2010 on my truck. A bit of History. NOTE: This was before anyone was offering a fix for this. Back in 2010 the dealer quoted me $1,000 to fix the ABS issue and i was like screw this I know enough about electronics to fix this myself so I took the ABS module apart and replace the transistor myself.

You should get the code no matter what that's the best way to check the issue. Currently you are limited to the dealer unless you know someone with DRBIII tool ? By the way it's not a relay: MOSFET - Wikipedia The metal–oxide–semiconductor field-effect transistor(MOSFET, MOS-FET, or MOS FET) is a type of field-effect transistor (FET). It has an insulated gate, whose voltage determines the conductivity of the device. ... In "depletion mode" transistors, voltage applied at the gate reduces the conductivity.

(CTM) CENTRAL TIMER MODULE I can only read 6 DTCs Wiper Park Switch Key Cylinder Disarm Switch Door Lock Switch Door Unlock Switch Module Hardware Fault 1 Module Hardware Fault 2 @ SilverMoose How about you try this: enable/disable horn honk when locking doors This process should work on all second gens (or at least late model second gens with factory keyless entry) gas and diesel alike. should also work on dakotas and durangos. with door closed, put key in ignition and turn key to the "on" position without starting. on the keyfob, hold down the "lock" button for 4 seconds, and then push and hold the "unlock" button while still holding down the "lock" button until you hear a chime. release both buttons, turn the key off, and you're done! make sure NOT to hold down the lock button longer than 10 seconds before pushing the unlock button or the process will not work. 3rd/4th gen trucks have a similar process to enable/disable horn report on door lock, but instead of using the unlock button after the 4 second period, they use the panic button, otherwise the procedure is identical.

Since you are in the beta testing team of my overhead gauge. Whatever you do don't replace the CTM yet until you receive my beta test gauge please. You will be able to read the codes if there is any, i would really love to see the log files. Just keep this in mind ok.

Oh man I don't have all the IDs nicely organized in one place but all over inside the code, it will take me a while to get it all. Some of the messages are unknown even to me. Let's start with brief explanation off the CCD BUS. Messages on the CCD-bus are flowing in a series a bytes. Every message starts with an identification byte (ID byte) There’s no way of knowing what every single byte means. Some messages can be reverse engineered by trial and error. The last byte is a one byte checksum value, inbetween is the message if any. The checksum byte is calulated by summing all the ID and Data Bytes. 256 is then subtracted from that sum. The subtraction will end once the checksum falls within 0-255 decimal range.

No sorry that's not recommended hooking up power to a junkyard vehicle with most of its wiring probably messed up. @ Mopar1973Man when you have a chance and you have your laptop setup you should set all the ID options to ON in the log settings menu, then go back to the main gauge and try to take a log file.

I'm curious what you're going to see, go ahead try it. I guess on my next visit to salvage yard i will grab the PCM from older pickup truck for testing.

Hi guys, I really appreciate the support and help with beta test. Mike's (mopar1973man) ABS issue was really helpful with improving software and upgrading couple things. Nick's (Me78569) automatic transmission testing helped to implement extra diagnostic information (transmission temperature, current gear info, OD lock etc.). David (SilverMoose) when you get it please check every possible issue and let me know what you think. I hope we can make beta version way better and useful for everyone. For the rest of you let see where we can go with it soon in the near future. Chirs O

That sounds about right I lost the count how many years I was married but I like this

I would just like to let everyone know currently out of the 3 beta testers ( Mopar1973Man, Me78569, SilverMoose ) Mopar1973Man and Me78569 currently are playing with the device, busy trying to finish SilverMoose beta gauge. Message received today from Mike: I'm actually glad it's helping out, hopefully it will help all the 2ND gen truck owners in the near future.
