In a long-winded way, Im saying your vehicles OBD connector, also known as the DLC (Datalink connector), may be damaged from possibly years of OBD scanning and, dare I say it, Front probing.. I guess it's in the same place as the 1.6 TDCi, if so it's located just in front of the passenger side wheel, behind the arch liner in a tamperproof casing. This is a simple voltage check using a voltmeter and fine probes. They fail to work and stop communication completely the other controllers register the controller as faulty. That's like $1500 plus labor if I am not mistaken. P0100 doesnt give you a lot to go on. .

In a workshop. We test these units on a purpose build HIL (Hardware In-the-Loop) test rig that replicates all driving conditions, this allows us to replicate any fault described by the customer and eradicate Ford instrument cluster problems. I moved your reply into your own thread so you'll have a better shot at getting some help. $64.95 . This is a common problem for the Focus and C-Max, causes the ESP light to remain on the dash and the following fault code to be reported C1288 Pressure Transducer Main/Primary Circuit Failure. Many a good tech has been caught out by jumping the gun and calling a perfectly good controller faulty, only to find the problem is still present with a shiny new spendy one installed. Check the cable itself for damage, and check the plug at the scanner too. This causes a no-start issue. This content is owned by moc.sotuaytsur. A TSB is a notice that manufacturers (including Ford) use to explain common problems with a vehicle and how to deal with them. The newer it is, the more likely it is that more modules are communicating with the PCM. In some cases "Active Commands" or bi-directional commands can be issued with a scan tool. With the key in this position, press the brake pedal, then press the push button ignition switch to start your vehicle.

Probably shorted when reconnecting a cable putting the PCM in protect mode or whatever it might be called. And finally, if both wires are open in one of the branches of the network, only the modules that are on the open side of the network will be affected. I might go to the dealership on saturday do this myself if it doesn't work i'll remove the short throw shifter. It is mandatory to procure user consent prior to running these cookies on your website. Started 22 hours ago, By TCS/Electronic Stability Program Module (car options and model dependent): if data-bus wiring is damaged or module is defective, this can cause an OBD linking error. CAN networks, as you know, connect all the controllers together using a twisted pair of wires known as the CAN lines. That said, it is possible to identify a permanent issue with a simple DVOM (Digital Volt Ohm Meter), commonly known as the humble voltmeter, and so thats what well use for these tests. In many cases, this may require a bidirectional scan tool. We then went digging for the powers and grounds to this module. I have now ECU and instrumental cluster connected,from other focus.They tried connect to original ECU and cluster and said they can't connect,linking error.So they change ecu,cluster and same,could't connect. The other day I was driving arroud the city and a warning light came up.

You will need a lab scope to see this. Ford Focus . For a better experience, please enable JavaScript in your browser before proceeding. Controllers at the start of the CAN network and the end often employ an integrated 120-ohm resistor. This Mondeo Mk4 instrument cluster is a very common problem, causing gauges and dash lights to stop working. The ground should be inspected first. This means that the exact fix will still depend on your vehicle's make and model. With the ignition switch OFF, you should have the voltage readings that were mentioned earlier. Pasted as rich text. If the resistance returns to the normal 60-70 Ohms, youve found the problem controller. 2020 FORD TRANSIT 3.5L NO COMMUNICATION WITH PCM. You can disconnect the connector at the module as a test. Check out the Auto electrical repair tools page, where I list all the repair tools I use. When a vehicle has U0100, most of the time, it won't run or drive anywhere.

The check engine light will be illuminated. Started Monday at 08:19 PM, By Free shipping . The first is that if damage occurs to one wire, communication should continue between the modules, but diagnostics will likely be affected. If however the scanner is new or new to you, go ahead and check your scanners capability. This using Ohms law makes the measurable resistance of 60 ohms. Modern vehicles typically use a few different types of communication systems depending on how important the message is. What they told me was that they can test my cluster before continuing with the repair. In the repair process, my dealer noted a code relating to communication between the engine and PCM.This led them to replace the PCM (1 day waiting for part). Someone last summer chased a similar issue. Bus + circuit # 914.and is found on Pin 2 of the DLC, Bus circuit # 915.and is found on Pin 10 of the DLC. Started February 27, 2019, By The voltage for this network ranges from Zero to battery voltage, that being 12V. The ISO 9141 network, is a single-wire, and is often identified as Circuit 70.

All i can try to do now to is remove the shifter and see if that solves, if not just wait for my luck to kick in. Place the negative probe on terminal 4 and the positive probe on the chassis ground and note the reading Repeat this for pin 5. These were the Engine ECU, TCM ( Transmission ) and the ABS module. To identify individual controllers, manufacturers generally use acronyms like PCM (Powertrain control module), ECM (Engine Control Module), TCM (Transmission control module), BCM (Electronic brake control module), or EBM (Electronic brake module), or BCM (Body control module), IPCM (Instrument panel control module) you get the idea. The contact owns a 2012 Ford Focus. With the battery disconnected (ground terminal). They should look similar. So I decide to do triple check and bought a bit better fault code reader. Any Ford ECM/ECU/ PCM with -12A650- in the OE part number can be repaired. How to Diagnose ECU Communication Issues? The readings between 2.5 and 3.5 volts indicate normal. A visual test comes first. I also contacted people on eBay who claim to repair clusters. I tried disconnecting the battery but no luck. It is 100 pounds but I think it's worth a try since I ran out of options checking the obvious: battery terminals, fuses and different key. It can be found in the console storage compartment, cup holder, or other location depending on your vehicle. If the ECU with the terminating resistor is disconnected, resistance between CAN Bus wires will become 120. Same fuse powers cigar lighter too IIRC. Good luck, hard to say without codes or looking at the car. Clean the battery terminals and other connections too: make sure each terminal lug has a healthy connection onto the cables; follow the black wires down and find the spot that the wire mounts onto the car frame. 1,25cc. Some of the common controller names include Control modules, Controllers, Computers, CU, CM, Modules, and Microprocessors. 8.7 VDC is well below the minimum threshold (10.5 volts) to get anything to behave properly. Low voltages may distort your results. There is no need to re-code or reprogram your instrument cluster once you receive it back, just plug in and away you go. The resistors are commonly controlled module integrated but may also be embedded in the circuit. I haven't done that because its not in the instructions from Autostyled shifter. i have the same problem on y 2007 ford focus, the car will crank but not start, it says engine systems fault, computer cannot read ecu, i have tried everything from testing the ecu, cluster, fuses, relays, reprogramming, coded keys, wiring but the car will not start, the diagnostic machine cannot read the computer on the car, no signal going thru, i was told to scrap the car or sell it as is, this will really really break my heart and shatter me into pieces, any ideas, Out of these cookies, the cookies that are categorized as necessary are stored on your browser as they are essential for the working of basic functionalities of the website. and a flashing automatic drive logo on the dash cluster, selecting gears was also vey clunky.
