Volvo S40 SRS Airbag error CFFF or 53247 internal error. Fault finding and repair.

Just you my friend to go deep into it and never give up, absolutely amazing top job 👍👍👍👍

Thanks Igor! 👍👍👍👍

[@viktorsigg4212]

Some good info for anyone looking at this. If you notice @22.22 in the video, the transmit data from the module is just sporadically low signals. What happens is that when the module have wrong configuration (noticed the yellow warning label that the module is matched to the car and should not be removed? 😄), the module transmits some few packets on the bus during startup. After about 18 packets at interval 10 Hz the module seems to go to sleep and stops transmitting other than an ACK signal for every packet recieved from the bus. That ACK signal is what is shown in the video, just a single bit transmitted. The module is fine but needs to be reprogrammed with correct config data (i think). The first packet sent on the bus (from my module atleast) was 0x00 00 00 00 80 00 00 48. After that came one 0x00 00 00 01 80 02 00 6C followed by repeated 0x00 00 00 01 80 02 00 24 about 16 times before it went with the ACK only. ID was 0EE0500A for my module but is probably specific to year and manufacturer.

Excellent video. I had the same fault code earlier this year and after speaking to a few ECU specialist's i was told that the car needed a new ecu and you cannot fit a second hand one as it needed to coded to the car. So £600.00 pounds later it was fixed. Top man.

[@LMAutoRepairs]

As you can see it is fixable....😉 Thank you for watching and for your comment!

[@ryanh3285]

So a second hand one didn't need coding?or did I've seen someone with the same car as mine on a forum saying surprisingly it didn't need coding either for Honda people just presume they do .

[@LMAutoRepairs]

You are talking about a different car, this video is for a Volvo and for a specific model, not for an Honda... Different cars, things might be different, and unfortunately never did it on an Honda... 👍👍👍

[@ungask]

Don't power up SRS module in the car when it's upside down!! You could easly fire the airbags in the car, because it will think it is rolled over. Best way to test airbag sensors is to connect on the bench to the diagnostic tester, this way you avoid unwanted detonation! Second way to secure yourself if there is no possibility to test on bench is to just unplug drivers airbag, deployment system would be disabled because of fault you created. Please be safe when working on Airbag systems!!

No, SRS will not deploy airbags when the car is stationary engine is not working and seat belts are not fastened.

[@petr_car_fix5828]

@@Qban220 , not correct. Engine may not run , belts in any condition, key in on position (even in R )and airbags can fire if someone move module, its very dangerous!

DIM "configuration fault" means DIM is configured to have a particular module connected to it but has no comms to it. Ford's idea of clear informative descriptions. Everybody seems to be doing this nowadays. Oh, and FFS, don't use a test light on airbag wiring. Digital multimeter until you are 100% you know which wires are real GND for current grounding test.

Very nice videos! Can you please give me an advice regarding a W211 2.2 CDI ECU? The car didn’t start, someone worked something in the ecu and now the car works fine when the ECU is out of the case. When the case is on, the car doesn’t work. It seems that some of the pins of a chip are shorted together on purpose. Can you please point me in the right direction? Thank you!

Hi there amazing step by step on this video, I actually have a question did you say that the corrupt data was down to low battery voltage, as I also have the same problem with my c30 not long after I bought it I started getting battery voltage warnings so I changed the battery and all seemed OK however I ended up with srs airbag service light too, Im wondering if it could be a similar issue? I'm based in the south of UK would it be possible to send you my module?

[@TTLmitch]

I just remembered the fault code from diagnosis was 005B

Very good job once again. I'm not into car repairs too much, but these are very interesting to watch. Out of curiosity, is it hard to find flash dumps of vehicle modules? Sure some can be found, but generally speaking of them? I did change obd parameters from my previous bmw as I added cruise control etc. but I remember I was bit sceptic about software I used and even though I think there was option to backup I was still worried if it might have damaged program so that it possibly would've been rendered unconnectable via obd. Not exactly same thing, but kinda proves that apparently I legitimately worried about possibility.

[@LMAutoRepairs]

Generally speaking, is not easy to find backups for modules... Thank you for watching and for your comment!

@@LMAutoRepairs I kinda thought so. Don't know how copyright things etc. work on this kind of things, but it would be nice if someone hosted webpage that would have all contents centralized. Though likely it would be put down by automotive industry. Then again there's been talk about repairability of things around globe. I would be good if makers would be forced to release codes and schematics for all, say in something like 10 year old vehicle. Interesting to see if that repairing thing actually hits it self through globally. I certainly hope so.
