SBC tool question
Has anyone got experience with an ecutool SBC Tool to enable and disable the SBC. it is sold online for $89.99 by ecutool.com but there are no user notes or comments. I need to replace my SBC accumulator. The job looks simple but with out a Star code reader it becomes complicated.

Assuming you're in the USA, SBC now has a 25-year warranty. Accumulator is part of it. Take it to a dealer.

Thank you for the response. Already aware of the 25 year warranty, and had it to the dealer. Unfortunately, the response was that they will NOT replace the accumulator until there is a major code failure of the SBC itself.
The accumulator is under 60bar and continues to send a warning message to take the car to the dealer for brake work.
Replacing the accumulator, although tight quartered, is relatively straightforward except for shutting down and restarting the SBC logic.
Hence the question about the Ecutool for enable/disable.
I would still appreciate feedback concerning either the Ecutool or another inexpensive way to disable/enable the SBC.
Thanks.

The pressure reservoir is listed. Damage code 43 159 Pressure reservoir, hydraulic unit.
Crappy dealer it seems. Escalate to regional and if necessary national offices. Reduced pressure means increased braking distances and possible crash. Document everything and insist they put everything in writing. Pressure reservoir should be 72 - 102 Bar. Anything less is sub-optimal; you can be sure if they found it on a scan they would tell you it needs replacement. If you can't get it replaced by them, be sure to name and shame them on this forum.
If you still are willing to pay for it yourself, post a request here, the SL sub-forum, and the E55/63 sub-forum to see if there is anyone in your area with a system that will de-pressurize the system. I'm not familiar with the Ecutool and would recommend you contact them directly.
Let us know how it works out for you.
EDIT: At one time the pressure reservoir was *not* covered by the SBC warranty (originally 10 years). Maybe the service advisor should try reading the current 25-year warranty document.

This place is a joke.
The accumulator is 100% covered if it's setting a code. Either you or the dealership are misinformed.

I hate it when people don’t answer the actual question.

I’ve not used the tool, looks cool though. Please let me know how you go! There is another method however, a little more complicated as you say...

starting at 1:10 is the process to disable it without using Star.

EDIT: Clarification from the technical documentation. Upon system activation, accumulator is charged to 160 Bar. SBC system then activates left front caliper, right front caliper, right rear caliper, and left rear caliper. Caliper activation reduces the accumulator pressure from the initial 160 Bar to the lower level.
If one needs to disable the self-check and does not have STAR or equivalent, just unplug the electrical connector from the SBC unit. Again, this does not depressurize the accumulator, it simply disables the self-check (or Pre-Drive Check in the documentation). One will get an error code on initial startup and a stored code will remain in memory until cleared.

Do NOT use that video to replace the accumulator! That video shows how to disable the self-check; it does NOT depressurize the accumulator. Technical documentation indicates the accumulator is charged to 160 Bar (>2000 psi) although in STAR test it says 70 - 102 Bar should be seen and one should see 60 Bar at the calipers. Anyone using that video and then attempting to remove the accumulator risks receiving a blast of pressurized brake fluid in the face. Use STAR or equivalent to depressurize the accumulator which will leave a residual pressure but no (or minimal) volume of brake fluid. Plus, after R&R of the accumulator, you will need STAR or equivalent to ensure the system is properly bled.

Thanks for the correction bbirdwell! I didn’t know that.
