I need your help again
it's still about my little construction site, the 2. V8. Soon he'll be ready to perform, but there's still a few things missing. Among other things, there is the ABS which does not work. When I turn on the ignition, the light in the AI doesn't shine. I can rule out switches and relays, we tested that. You can hear the relay switch. The relay fuse was defective, but that was not the cause of the problem. We also attached the computer once and read out errors, there comes ABS front left and right, as well as back left and right.
How do I keep driving? Is it possibly the ECU? Or what else could be considered?
Thanks for the answers
Greetings Thomas
