Looking for some guidance. I have a Mack GU813 with a ABS and electrical malfunction light on. I have a standard Bendix ECU. I have tried to swap it with a good one from another truck, and tried swapping the instrument cluster. Neither fixed the issue. The code is for ABS warning lamp circuit fault. If anybody has any troubleshooting ideas please let me know. Or if you have seen this code before, please let me know how you found the problem and what you did to fix it.
