ECU to BCM loom twisted pair

[dil6222]

Hello aIl ive checked the can wires and cant find the
Issue I even went as far as taking complete dash out to get to complete loom that
runs along bulkhead behind dash
I ran test light between all sets of can plugs and visually checked all seem fine
I even checked for breaks between immo ring and IPC/clocks.

the only thing that I noted was abs light is on dash also I checked plug on abs controller where can wires route through to get to ecu the plug had water in bottom near blue gel I dryed it but didn't make a difference i also tried bridging can wires on abs controller plug but again no difference. As I said abs light is on but its not storing any fault codes which is strange. light but no codes ??
service light remains non appearing and Insp still shows 0 and won't reset. Need a bcm and ICP dump if anyone has 1
Would a dead Kline wire cause same issue?

If k line was dead you wouldn't have comms with engine ecu try unplugging immobiliser module the US type ones go down cause non start faults also no comms

That's what I thought as I have Kline comms it can't be that.
Im thinking along the line of abs controller as it gives me negative answer to service error in opcom and the abs light is on constantly and as it's first in chain before bcm etc will check immo though racing snake cheers for extra info
I'll give in when im dead lol

PS what is the I'd I should be programming to bcm and Ipc as it only programs 8 digits is this correct as vin number is longer?

SOLVED

after trying countless solutions and checking abs ecu
and removing complete engine to instrument wiring loom and Can twisted pair half a dozen times
( pictures later ) I found the devil hiding away in a little green wire
about six inchs from the abs ecu plug wrapped inside the twist was a pin hole no or visible break whatsoever just a tiny hole probably 0.25mm.
I cut the piece out and rejoined all good now everything works

Conclusion

I nearly ruled out can wires as tested with test light but after checking all other possibilitys knew it had to be a break I had already checked them few times so as loom was out I checked again a inch a time under a bright lamp and found it fixed and coded complete system on my living room floor lol.

worth noting is that immo/service light will be completely gone non appearing for this fault , the light will come back when wires fixed and ipc may play up and not program till fixed also.

i will tape up can wires separate and then tape them into loom for added protection so it shouldnt ever happen again.

big thanks to racing snake and ashraf
