Looks like the black plug with wires going through the bulkhead is the one I thought we were still searching for . Leave the Black plug disconnected and now working under the bonnet check the CAN BUS resistance at the ABS connector, it should be 120 ohms with the PCM connector plugged in. Forget about the BCM and obd end, you have verified that is ok. If the above test is 120 ohms the break is between the black plug and the ABS connector. If its high resistance or open circuit the break is in the engine bay. I have 120 ohms on abs conector and black plug end i though there was a resistor in the ecu so it should be 120ohms I have 2 lots of blue/white wires in foot well on different plugs the other side of that black plug I have open circuit Quote Link to comment Share on other sites More sharing options...

Hi I’ve done the check on the abs and black plug 124ohms with the pcm plugged in the other side of that black plug is open circuit that were not the same wires I was checking before there seams to be two sets on the other white plug Quote Link to comment Share on other sites More sharing options...

Dan62 Posted April 10, 2021 Share Posted April 10, 2021 The problem not working with an accurate wiring diagram. Looks like you'll have to check wire continuity from plug to plug for each wire to check you're on the right BUS. Quote Link to comment Share on other sites More sharing options...

I’ve now plugged everything back in and checked pins 6-14 obd plug now have 26 ohms only ,so I’ve reconnected the battery to see if it will start , and now I have no ignition the stereo and dash lights up and the remote key locking all work, maybe the can bus is to low on resistance I can’t get ignition or there is more then 1 broken wire ?

Dan62 Posted April 10, 2021 Share Posted April 10, 2021 You'll need to go through the process again. Very odd that the resistance is now so low. At least you know your way around the connectors now. Quote Link to comment Share on other sites More sharing options...

Found the blue plug on the BCM wasn’t connected properly I have ignition and same faults and 133 ohms still on obd plug im thinking the BCM could be the fault as it all passé through it is there any way off checking certain terminals to check the resistance through it Quote Link to comment Share on other sites More sharing options...

Without a wiring diagram you would have to reverse engineer the circuit, starting at the obd port which is the only connector you know for sure is the right BUS, pins 6 & 14 1 Quote Link to comment Share on other sites More sharing options...
unofix Posted April 11, 2021 Share Posted April 11, 2021 As Dan62 says without an accurate wiring diagram it is going to be a slow process of going plug to plug wire to wire. The fact things have now changed and nothing has been done other than disconnecting and reconnecting plugs makes me think that you have disturbed something. I still think you have a bad connector, so go back to each of the connectores you have been checking and disconect them. When you were testing the female contacts could you have maybe stretched the contact open a little so that it is now making a poor contact ? The fact you now have only 23 ohms on the OBDII port would mean that you have a part short circuit on the CAN. Again go back and disconnect the connectors you have been working on and keep rechecking the resistance on the OBDII. Quote Link to comment Share on other sites More sharing options...

The 23 ohms is gone it as a plug on the BCM im back to 133 ohms on 6-14 can the white plug in the picture seam to have double the can bus Same wires Quote Link to comment Share on other sites More sharing options...

unofix Posted April 14, 2021 Share Posted April 14, 2021 Hi Wayne you have done an excellent job of testing the CAN wires. As you say you need to find the other end of that lead since it would seem that the problem could well be at that end Quote Link to comment Share on other sites More sharing options...

monkey_wrench Posted January 24 Share Posted January 24 Üdv mindenkinek! Magyarországról származom. Elnézést a helyesírásomért. Nekem nagyon hasonló problémám van, mint a frenchspannerrel. Sokáig nem parkolt az autóm, csak két napig nem használtam és mikor indulni készültem, kiírta az "indításgátló aktív" üzenetet. A műszercsoportban is volt forrasztási törés, amit kijavítottak, mert szerintük ez jelzi a hibát. Ezt követően a diagnosztikai programmal már nem lehetett törölni a hibát, mert a rendszer nem kapott információt az ABS-től. Lehet, hogy ugyanazt kell tennem, amit a megjegyzésekben olvastam. Ez komoly munka lesz. Remélem tudsz nekem segíteni! Quote Link to comment Share on other sites More sharing options...
monkey_wrench Posted January 24 Share Posted January 24 Hi everybody! I come from Hungary. Sorry for my spelling. I have a very similar problem to the french spanner. My car wasn't parked for a long time, I didn't use it for two days and when I was about to leave, it displayed the message "immobilizer active". There was also a solder break in the instrument cluster, which was repaired because they think this indicates the fault. After that, the diagnostic program could no longer delete the error because the system did not receive information from the ABS. I might have to do the same thing I read in the comments. This will be serious work. I hope you can help me! Quote Link to comment Share on other sites More sharing options...
Snekaac Posted Tuesday at 11:26 AM Share Posted Tuesday at 11:26 AM Good day,, I have S-max 2008 2.0 tdci,, and I have problem with (maybe) ABS module. Once I went from work , my ABS and ESP lights on. So I tried to stop the motor and then start again,,but Immobiliser was active 😳 . It srarted after 3 hours with no problems. But when I reached speed 15kmph (9mph) ABS and ESP hop up again.. speedmeter and odometer stop showing info and at the next start,, it wrote Immo active again. So, I checked all the pins on BCM, ABS, (ECU) that one in fron of left wheel. Canbus wires have 61,5 ohms between each other , but in the green connector of BCM is 122 ohms. Then I tried if some of canbus wires is connected to skelet-ground, but they dont. Diagnostic writes me bad power supply to ABS module,but I measured there 12,5V and 0,4ohms between +connector and +battery. -battery to skelet also 0,4-0,5 ohms. I cleaned all the grounds in engine space. Cca 12 wires, so other grounds should be OK too. And,, if I can start the engine, I can connect to abs, turn the motor off,,,then start and repeat it 1000time until I reach that 15kmph speed OR,, try to make a test of the ABS module. Then it automaticly lost the connection,, And at next start Immo will greet me again 🙂 this trouble goes away by its own,,, after 5 minutes,,next time after few hours 🤷 it is random. So,, is possible to have a ABSpump stucked,and during the test/drive, it will crash the connection? I thought it just write me some issues,,but there is no reason to lost te connection 🤷 Quote Link to comment Share on other sites More sharing options...
