Need help with SDS communication error
A few weeks ago, I went over to a friend's house to see why I had a white brake error message. We pulled error code C2131 and found the pressure reservoir pressure to be low. On the way home, my car went into limp mode and I had to be towed home. It had the red brake error message, ABS, ESP & voltage errors.
I first started with a new AUX battery, as it had a low voltage. (The rear/main battery is 1 year old)
I then ordered a new reservoir and am trying to install it today. However, I cannot deactivate SBC. When I instruct SDS to deactivate SBC, I get a communication error 8.600.0.
I found a blown 5A fuse in the engine compartment and replaced it. I have my main battery hooked up to a battery tender while I'm working on it and SDS shows I have 13.1V, so this is not a battery issue. Do I need to clear limp mode before working on the system? I cleared trans adaptations, with no problem, but fault codes will not clear. All fuses have been tested and none are blown.
