Repairing a Flooded Tesla Model S : HOW-TO

[jelloslug]

Ruled out #5 tonight.

Swapped a new brake sensor cluster in and I'm still having the same issue, I opened up my flooded one for the fun of it (that I didn't throw away as yet) and made a keychain out of it

Did you see my post?

Repairing a Flooded Tesla Model S : HOW-TO

I think you are onto something

 

[Btr_ftw]

These are the possible things that could give me the regen, abs, traction control issue, it may be a combination of two or more of these items or perhaps it's just one thing that's ruining it all.

1) bad wheel speed sensors
2) faulty motor speed sensor
3) faulty abs traction control module
4) battery pack not getting to operating temperature
5) brake cluster sensor (NEGATIVE)
6) poor wiring connection from drive unit to passenger side wiring harness
7) air in brake lines
8) brake power pump

UPDATE

now that I've ruled #5 out, I'm moving onto #7

I decided to give the brakes a quick bleed and found this...

Ideally, this should be CLEAR, especially for a car thats only a few years old and that doesn't rely much on its braking system. This color indicates the fluid going bad due to heat/overuse OR... since its hygroscopic it naturally tries to absorb as much water from its surroundings as possible..... for a flooded car this sounds ideal...

time to flush this badboy

 

[jelloslug]

That stuff is broke fluid.....

 

[Nietschy]

wuuuoooow I think your on the right way here!

 

[apacheguy]

That brake fluid looks nasty although note that mine was yellow shortly after replacement by Tesla and I was told this is normal.

NEGATIVE..

Flushed the braking system and the error is still there, hey well at least the fluid is clear now!


I'll be moving onto #4

I think you can skip #4 in terms of ABS, as I wouldn't think that the battery pack temperature is related to ABS.

Have you tried taking off the air filter and opening up the carb all the way. Hehehe!


I used to do that all the time with my 68 mustang. I am so glad those days are gone! Those old muscle car were really pieces of *sugar*!

 

[JPUConn]

All fuses and relays confirmed to be ok?

I was thinking more the regen issue, perhaps I'm trying to solve too many at once.

call it old, outdated, antiquated or obsolete, but I LOVE me my american engines...

Here is my other, other, other, other project

Where do you hook the battery up to that?

Which begs the question, have there been any sacrilegious ICE conversions of the Model S been done?

Very nice. Hard to beat GM LS engines. My toy is a bit older: Mark IV 454 cui with aluminum heads, full roller valve train and sequential EFI. Won't crap in your thread by posting pics.

It all boils down to the ABS. The ABS has the wheel speed sensors which again dictate regen and traction control.

There was a pic of a Model S stripped down to it's frame in the front with a big-block fabbed in to it, but it was later claimed to be a photo-chop.

Here it is: V-8 Tesla

so... is that a new center console? (I assume those round spaces are cup holders?)

Or... wait! I know... it's a mount to hold the charger handles... look you can hold 4 on either side!

onto #4. I doublechecked all of the coolant circulation pumps under the hood and they were confirmed to be working, HOWEVER, I did not replace all of the coolant valves (I only replaced one)

one of the pesky little buggers I couldn't see very well and quite frankly forgot about it, the other valve was high enough to the point where I thought it wouldn't be affected by the water levels...


sneaky sneakyyyy

here is what they looked like on the inside... (this is the better one of the two)

the car didnt throw any codes or harass me about anything when they were like this either... "coolant valves not working? no problem mon...."
