Thread: PWM Fault Code.

Well it is done and just with 1 and a half hours to spare in the US. Foxwell had the 530 on sale until midnight 31 December. But it was the 1st January 2021 in Australia. Just luck really didn't realize there was a sale. Free postage to Australia as well. Also the Foxwell will be able to access my Renault for an extra $60.

I was going to put up a list of differences between what the Nanocom can access and what additional information is in the SLABS ECU. But it is quite a few and some what complicated in the details. (Too much typing.) But if some one wants to know I can send a copy of what is in there by email. Not sure where I got this info from but there is 9 pages compared to Nanocoms 5 pages which seems to be a copy of parts of the 9 page paper. I thought it might have been from the Landrover Book but no sure about that.

Hope you all have a better NY in 2021. Rob

If you get to it check first the VIN stored in the ECM to match with the vehicle then save the same VIN into the SLABS cos if the ECM is not original it might have other VIN than the vehicle, IMO important is to have same VINs in both ECUs no matter which one you modify... I'm watching this with interest, good luck and happy new year

Good idea. Perhaps its the ECM thats wrong. The SLABS original? Hopefully I'll find out in the next week or so.

Watching this with interest myself!

(so that I can put a 2004 v8 SLABS in my 2000 v8 and finally lose the CDL-caused warning lights without snipping wires as a workaround!)

It is my guess that a missmatch in VIN numbers is why I get the PWM error.

You can avoid that by simply locking the diff while the engine is running and not start the engine with locked diff.

Well the Foxwell N530 has arrived and I have done all the downloads, registering, etc. Sure I can read the Vin No. in each ECU. But so far I cannot work out a way to change the SLABS Vin No. to the same one on my Engine ECU. It is correct for my vehicle. But the SLABS one is incorrect. Still get PWM code error. I have asked Foxwell is there a solution and have not had a reply yet. I don't think my SLABS has been replaced when recalled. The recall is still listed on the Govt web site for recalls. I have asked the Govt web site if they are still listed are they still applicable even after 20 years. Maybe I ask Landrover to do the outstanding recalls.

Now what?

The Foxwell will change the VIN and then return it back to the correct one for the original SLABS. But it will not let me change the incorrect VIN on the SLAB I want to use as a replacement. When I have the original SLAB connected with correct VIN there is no PWM communications fault. So either the incorrect VIN causes this or another form of fault in the replacement SLAB ECU. The Foxwell has also finally allowed me to calibrate the level sensors of the airbag system. After quite a few unsuccesfull attempts. It just keeps the airbags at the set level. None of the other airbag functions work. My next play will be to save the settings and transfer them to my computer and see if I can change the VIN and then reload the altered setting and see if that takes. The government suggests that if a safety recall is on their site then it should be actioned. Interesting to see what Landrover says to that after almost 20 years.
