Had exactly the same none crank on a 12 plate Focus today, codes for both rear ABS sensors, quick Google and found your video, replaced one and it started, then replace the other, thanks very much you saved me hours of going round circles.
Hi Ryan, just seen this video and read a few of the comments...Thank you for posting. I'll hopefully explain why the car could not be started with an ABS fault logged. Please read on and try to stay with me. Hopefully this will enlighten some of the commenter's below that this is indeed NOT a poor design. (@phareztrinimand) On this car, being a keyless start, there is an electronically operated steering lock. (ESCL). Now you'll all agree that driving a car with the lock still engaged or worse still the lock coming on whilst driving is a very bad situation with only one possible ending. So to prevent this from happening there are a good number of safeguards in place in the vehicle software. The ESCL is controlled from the Body Control Module (BCM) by a LIN single wire data bus signal AND the BCM also has control of the power supply to the ESCL too. (Early variants the ESCL is controlled by the Keyless Module (KVM). So the ESCL is only able to operate once the BCM has the correct state of affairs. There are many signals from around that car that are evaluated before the ESCL receives its power and the LIN command to operate. One of these is the vehicle speed from the ABS module. This message is sent from the ABS module over the CAN network and is a periodic message detailing the speed read by each wheel speed sensor and also importantly a quality factor (QF) component. This QF byte is calculated by the ABS module and if any of the sensor readings are suspect the QF byte is set to BAD for that sensor and a corresponding fault code logged. The ABS compares the readings from the sensors and can determine if a sensor is really bad rather than just a locked wheel skidding. For the ESCL to operate, the BCM has to receive "a valid vehicle speed of zero." This means a CAN message saying "My speed is 0 kph and my QF is GOOD" for each ABS sensor. If two or more sensors report a bad QF or the ABS message is not present then the ESCL will not operate and will remain in the state it is currently set to. So for instance if the ABS module went off line whilst you were driving then the BCM would not receive a vehicle speed signal and the ESCL will not come on. As for starting the car, the ESCL must release before the engine can be cranked and started. You'll hear the lock operate when you get in and press the brake or unlock and open the door depending upon the software level. The BCM/ESCL/ABS/PCM, (+KVM) are all immobiliser components and if any faults exist the car is not allowed to start. So for the ABS fault in this video the BCM cannot evaluate a valid zero vehicle speed and therefore will not operate the ESCL. For safety the car cannot be started or driven. For those still reading along also be aware that the RCM or airbag module can prevent the ignition being turned on. This is because the RCM and ABS module share sensor information (Yaw/Lat/Lon) and if they are not matched then the ABS sets a fault which once again disables the ESCL and immobiliser will not allow starting. So frustrating as it may seem, the logic is there to prevent danger by design. This ensures that customers are not lost and the hopefully come back to by another Ford when the time is right.
I first heard about this a few years back when people were starting to try swapping the ecoboost into other cars, where they'd have to swap the dash, whole abs system, everything. I've never seen it on a customer vehicle yet. Good find!
Been there myself on a similar Ford Focus, wasted hours checking wiring trying to get to the bottom of it. Changed abs sensors as last resort, started straight away.......I hate car designer's sometimes!!!
Yes had this a few times now on fords. I also don’t bother with aftermarket abs sensors now as I’ve had a lot of issues with them.Genuine sensors aren’t to badly priced.
I’m working on a Mini Cooper crank but no start with abs sensor fault codes I’m just wondering is this the golden bullet at fault lol il be blown away if it is 😮😮
@@mrautoservices7354 I’m so intrigued as too why this fault would cause that to happen what’s you’re theory if you don’t mind me asking I can’t quite come up with one lol
Check out the Un-Fixable Focus series here 🙂 Its a 4 video segway. Slightly different but does explain the difference in the sensors. www.youtube.com/@autodiagyt/videos
I've had this exact same problem on a @2010 focus, no comms faults, between abs and ecu or cluster, can't remember exactly, abs sensor faults on rear. Customer went into shop, came out and wouldn't crank, AA man spent 3 hrs on it and was towed in to me. Luckily I asked on a forum and 1 chap had the problem before. The no comms bit threw me, but plugged in 2 new sensors and fired straight up. Couldn't believe that would cause a no crank, no start 🙄
Does Ford ever consider that being broken down or stranded in certain locations or situations can be dangerous for some people.. they need to use their brains .. i’ll never buy a ford ever again
Hello mate, please check the videos from Automotive Diagnostics and programming… he is dealing with the same fault codes, but the car cranks amd starts 😮😮… nice videos on your channel cheers
This was a no crank case, The car network would not allow the vehicle to start due to both rear abs sensors being faulty. This vehicle has park assist option so its more or less a safety concern, The abs reports the sensors are no longer functional via the network and the bcm rejects the start request by the driver.
These is intentional by Ford reason being they want you as the owner of a Ford to go to the dealer to fix the problem. Once a car is sold by the dealer, other than servicing repairs by the dealer is only way to make money....
Vauxhall did the same. They have been programming in random faults to appear so people will go back to the dealerships. Then it's a charge for a hire car, reading fault codes, buying parts to try, then a final bill. A relative had this on his with "ESC fault", the code was cleared and there was no problem until the next one a day later on a different car about "ESC service required ". No faults found so reset. Then one about headlamp level control. All nonsense. The two cars were exactly 4years old!!! So it will be interesting to try and download any programming in the ECU and see what else to expect. They lied for years about road traffic sign recognition camera in the front that put the speed limit up if it saw a road sign. What rubbish, it was taking it from the satnav, so doesn't see signs and doesn't know about 20 limits - unless you pay loads to update the satnav.
2013Ford will not start everything comes down will not turn over brand new starter brand new battery new relays all fuses are good will not turn over for nothing push the button everything lights up that’s it stereo everything comes on headlights your name is it all works except no start hope you hear back from you
According to the diagrams, this vehicle uses digital wheel speed sensors. If i have to believe the diagrams, the previous model used inductive sensors. Case of incorrect parts fitted by a @#$%^& "mekanik".😉😉😉
I did get two front wheel speed sensors,it just unlocked the steering columm then it went dead again Now complaining with invalid data recieved from abs control module
