Re: Tesla Small Drive Unit (SDU) Gear Box Fluid leaked

Opened the motor leads cover. All o-rings look clean and undamaged. The cover looks clean too. Planning to make a gasket on the cover using the gasket maker I used to fix the other leak - permatex optimum black (sensor safe). Though that was metal-to-metal, this will be plastic-to-metal. Should work...

Yeah. If it was LV I'd do it without thinking.

Re: Tesla Small Drive Unit (SDU) Gear Box Fluid leaked

O-ring + make a gasket = almost a guaranteed leak. Best to make sure all the o-ring grooves and bores are clean and not scratched. Use new o-rings. Isopropyl alcohol should work well to clean all of this. Make sure it's completely dry before you assemble it. Thank you. Cannot clean inside of the IG...

Planning to clean the LV drop in board with just a contact cleaner.
Not sure what to do with the HV IGBT section. Doesn't seem like it's dismantable.

Re: Simp BMS

I not used IVT-S with simpBMS but from looking at the code it uses big endian for current and voltage whereas Zombieverter and other OI solutions use little endian. That's a bummer 😔 The IVTS setup is the factory default that is to be used with the SimpBMS, makes it easy on anyone buying one. No ne...

Re: Tesla Small Drive Unit (SDU) Gear Box Fluid leaked

Ok. I'm prepping myself to pull the unit out and so refreshing my memory how I took things apart last time. In doing so, looks like the gearbox and the motor (rotor and stator) section are suppose to have gear fluid. Before I was thinking that only the gearbox section should be in the fluid. https:/...

Folks, Sometime ago I resealed my SDU due to gearbox oil leak. I then refilled it with fresh oil. image.png image.png I did not have the setup to spin the drive unit at the time.

Re: Can't Initialize Isabellenhütte ISA Sensor. [SOLVED]

According to the data sheet the command ID can be changed. As you have a Ardunio Due it may be better to run Savvycan which allows all messge to be seen. You could also go through all the IDs automatically until you find the correct command ID. Brilliant! Thanks for your help! For future somebody w...

Ok. Some new findings. Either after running the above factory reset command new IDs came out or after playing with the code I filtered for additional IDs. 0x620 - unknown. but I suspect this is where the current is read. having trouble finding 12VDC load with >1A.

Re: Tesla Small Drive Unit (SDU) pot tolerance

I think this can be marked as "solved" for now. I have the pedal connected to the SDU via a terminal block. I re-seated the wires of the pedal on the TB and this made the values more steady. I also connected the ch2 of the pedal to the pot2 input, 'cause I was thinking that when unconnecte...

Re: Can't Initialize Isabellenhütte ISA Sensor. [SOLVED]

It looks like 0x620 is the current reading. You could try send 0x3D on byte 0 of ID 0x411 to reset to factory default settings, check CAN ids at this point and then initialise as before. Tried this without success. :( Within the ISA.cpp there's deFAULT function. Added the case to the code. Triggere...
