intermitten canbus failure is fairly difficult to diagnose and would require a multi-channel scope and a lot of time. if you can narrow it down to offending control unit, this would help with diagnostic but that means unplugging each one by one. otherwise you will need to find an experienced diagnostician and pay for the time, which will not be inconsiderable.
Need help with diagnosis of high and low speed CAN bus issues...willing to pay qualified person
Hello,
I am having communication issues with my 2006 LR RR 4.2L SC. The high speed can bus appears to be down/intermittant. Modules on that network include IC, TCM, PCM, ABS, etc. All of wich are not communicating with autel scanner. SDD usually does communicate, but scanning of module results different many times. Sometimes communicate and others not.
I also need good source for a spare key FOB of high quality.
If you respond, please be highly qualified. As I am using my LR for a cross country trip/move.
Thanks.
Steve
