Have you tried changing “MAS01180-AUTO HOLD functional status” to always active as well as activating the other channel?
Yes, I have tried doing both. All it does is make it so that auto hold is always active. (pushing the “Auto Hold” button in the center console will not disable Auto Hold after making these changes, orange light stays lit.) It basically just disabled the Auto Hold button, but still no green indicator in the cluster when it’s actively holding the vehicle.
