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.

- Chevrolet Malibu
- Honda CR-V (MY 2018, 2019)
- Jaguar i-Pace (MY 2019, 2020)

I will add a reference table to OEM part numbers later in the EV parts database I’m working on.

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)_/¯
