The iBooster made by Bosch is used in many modern cars. Most well known example probably is the Tesla Model S for the GEN1 and the Tesla Model 3 for the GEN2. But did you know at least 10 other cars are also using the iBooster? Below an overview of iBooster donor vehicles.
iBooster used in electric vehicles (BEV and plugin)
This page provides an overview if possible sources for used iBoosters, where possible including model year (MY) info. You can also check out the EV parts directory for manufacturer part number overviews (online soon).
iBooster GEN2
The GEN2 iBooster is a bit odd shaped and has the ECU connector pointing forwards.
So far only the pinout and wiring of the Tesla iBooster has been tested by EVcreate. So while our connector kit for GEN1 and connector kit for GEN2 fit the other iBooster donor cars too, the pinout for other donors have not been fully verified.

iBooster differences
The VW iBooster has an extra enable/input signal. Furthermore the CAN messages of various boosters are different.

btw vw up has similar device. Its worth checking it out. Connectors looks the same.
Thanks! I’ve added them. Looks like the eUP has the Gen1 iBooster. Will buy one for testing.
do you happen to have the part number larsof the eUp Gen1 Booster
Part numbers for the Volkswagen eUP Gen1 iBooster are:
– 12E614105B
– 12E614105H
– 12E614105K
Is it possible to get just all the connectors? Also is the Honda Accord wiring the same?
Yes, you can buy just the iBooster Gen 2 connector kit.
As far as I know the wiring is the same, but never tested / validated an Accord Gen2 iBooster.
I found a gen2 ibooster on a renault captur hybrid 2020
Thanks for sharing! I’ve added it to the overview as well as some others I’ve found.

Hi Lars,
I bought a ibooster of a Toyota Yaris IV hybrid. I cant get it to work consistently.
it works sometimes, but when i disconect the acc wire it dose not stop working.
the canbus always works, and i can see the data changing when i push on the connecting rod.
the other canbus seems to be to fast. when checking the signal with a scope the bit timing looks like 2 Mbps. to fast for canbus?
any hints?
Manny (alvast bedankt)
Hi Manny,
What I saw on other models is that it can take some time before the iBooster goes into sleep mode. How long did you wait?
Signal could be CAN FD. That goes up to 2 Mbps, but then you need a CAN FD dongle and software suite (I use this from Peak).
Hi Lars,
As I am writing this, I am also testing. And now it does goes to sleep after 3 minutes.
It did not do that before, so I don’t know what changed
The CAN bus on pins 16-25 is normal CAN @ 500.000(bit/s).

The data in this message changes when the break is pushed. even if the booster is not boosting.
The CAN bus on pins 10-18 in CAN FD @ arbitration 500.000(bit/s) data 2.000.000(bit/s).

when the booster is started there is one standard CAN message.
id:0x47C
data: 7C 10 03 E9 0F 0F 0F 0F
I use Savvy CAN for the CAN bus analysis. The CAN FD I captured with a logic 8 for Saleae.
Both CAN busses are active if the ignition wire is at 12V. when the ignition is open the normal CAN stops but the CA FD keeps sending data.
maybe the CAN FD needs a ACK to be happy ¯\_(ツ)_/¯

Dear Manny,
Did you solve how to enable iBooster from Yaris IV hybrid?
Apparently I have same unit and no luck to got it runninng.

Greetings, some time ago I bought a gen 1 ibooster for a Honda Crv 17-18 and I can’t get it to work, I’ve seen many videos on Youtube about this adaptation and the electrical diagrams and nothing doesn’t work, could you help me
Have not used or tested a Gen 1 CR-V iBooster myself so I’m not sure but perhaps it needs the CAN connections to be ‘valid’. You can try and add termination resistors.
It might also help to know the master cylinder bore sizes from donor cars as well, along with reservoir types and orientation of the iBooster (especially for the larger GEN 1).
Some booster orientations have the top bolt on the left (Chevy Bolt, Audi A3 e-Tron LHD), others on the right (Honda CR-V RHD). The Chevy Bolt and Audi A3 e-Tron do not use remote reservoirs, the Honda CR-V does.
In terms of bore size, the Audi A3 e-Tron has a 23.8mm bore, so too does the Chevy Bolt. And the Honda CR-V uses 25.4mm.
I have a Booster out of a 2019 Honda Accord 2ltr which is the same as the 2020- 22 Insight. There is only one 5 pin plug on these unit. How does one wire these up?????
Best Wishes
Peter
Can you email me a photo of that booster and the part numbers on the device?
I’d tend do conclude it is either not an iBooster or it is incomplete.
But even if the control part would be missing the travel sensor would be a 4-pin connector so does not match with your description of 5.
So I’m curious about further details.
Hi Lars, thankyou for the connectors.
I have an ibooster gen2 from a Porsche Taycan, it doesn’t seem to function or start in failsafe mode.
Pedal travel sensor and power are connected but applying 12v to ignition has no effect.
Any ideas on how to troubleshoot this one or is this ibooster dead?
Hi Paul,
Sorry to hear that. Unfortunately I do not have any hands on experience with the iBooster from a Taycan nor access to the wiring diagrams.
So I cannot provide any assistance here whether it needs different wiring compared to those from a Tesla or not.
Hey!
I had a question about the reservoirs, are each gen iboosters specific to that generation? Or are they interchangeable between gens?
(I have an accord (gen2) ibooster and I don’t want the remote reservoir)
I’m not sure about all models since more and more varieties arise.
But I do know my Compact brake fluid reservoir for iBooster and the Remote brake fluid reservoir for iBooster do fit on Tesla, Volkswagen/Audi and some Honda.
What is the smallest ibooster you have worked with so far? Do you have rough dimensions of it?
Think the Gen1 is more compact than the Gen2. Rough dimensions of both models can be found in my Installing the iBooster blogpost.

I have question about the master cylinders for Gen1 and Gen2 , will they interchange? I have a Gen1 from a Chevy Bolt in which I like to install a larger piston 1 inch master cylinder. I need for the 1 inch master cylinder have the same clocking as the Chevy Bolt I have limited space where the unit is installed. Looking at pictures I notice that the Gen2 have the same clocking but did know if they would interchange. Any help is appreciated,
Louis
The master cilinders of a Gen1 and Gen2 iBooster are not interchangeable.
