The RAV4 EV, the Mercedes Electric Drive/B250e, and the electric Smart cars, they all have a desiccant pack in the battery. The RAV4 EVs have some kind of little air pump on top of the battery cover, it's under the driver seat area, and it's quite noisy. It's one of the loudest things you hear...

After modifying my LDU to no longer circulate liquid coolant through the rotor, I would like to know just how hot this rotor is getting. I figure that it now can't dissipate much heat anywhere except to the stator, and to the rotor bearings, and I'm a bit worried about the latter; I think the...

Leading with this: as of this writing, no, I don't know how to properly fix the problem associated with this Alert. You Tesla owners who find this by Googling, the below may not even apply to your Model S. I'm putting this tale out in public to provide data for others do find, but I'm not...

I recently discovered the Blue Drops of Death on my LDU's speed sensor, so I removed it, cleaned it, replaced the rotor bearings "just because", reassembled it, and modified the coolant manifold to bypass liquid rotor cooling. Along the way I had to fabricate three different fixtures to remove...

Summary: I had an aluminum plug machined, modified the OEM LDU coolant manifold by cutting off the tube that runs into the hollow rotor shaft, milled a bypass channel, and pressed in a plug. I anticipate no more coolant leaks in my LDU. Background: The Tesla Large Drive Units ("LDU") of the...

TPD 1.1.42 has a view of the percentage of capacity that the Powertrain and Battery pumps are running. Views|Thermal|Pump Tool Monitor or Views|Thermal|Thermal Controller TPD 1.1.46 introduces a new tool: Pump Tool; it appears that it should allow running (or stopping) any of the three...

TL;DR: TPD 1.1.46 does not require licensing to operate, and is now available for "anyone". Via TIS subscription and download ($25 for two days), or from other places. --- Background The GEN2 RAV4 EV, 2012-2014, has a Tesla-produced drivetrain, which includes: Drive unit (motor + inverter) aka...

I have assembled a batch of diagnostic cables for use with Tesla Powertrain Diagnostics ("TPD"), which I can provide at my cost for those who don't wish to fabricate (solder) their own. The soldering is straightforward, but nibbling out the connector shell's side and center plastic is a little...

A Gateway module just hit eBay (https://www.ebay.com/itm/314423314345), $2,000, though it looks like it's been underwater for a month. New, Toyota's price is ~$2800. The RAV4 EV Gateway ECU bears a striking resemblance to the Tesla Gateway module used in the early Tesla Superchargers, which...

The telltale sign of TPMS sensor trouble on our rigs is that the TPMS ECU no longer receives a signal from a sensor, and rather than merely illuminating the Low TIre Pressure warning on the dash, it flashes it for a minute every time you start the car, and afterwards it settles to solid. My...

[For me, today, there is no "New Topic" button on the Marketplace forum, so I cannot post a new topic there.] The dealer who changed out my battery Aug2019 in Roseville, CA left off some/all of the plastic clips that retain the under-engine plastic cover. It looks like they just tucked the...

The story mentions that Jerry Palmer of Boulder has an "electric Toyota SUV . . . " which I am assuming is a RAV4 EV. It's not a large part of the story, but it was interesting to hear anyway. Link to NPR page...

This is probably posted in the wrong forum.

I use my RAV4EV as a daily commuter, mostly. The two times I've been away on vacation etc., I've been careful to leave the traction battery in a semi-discharged state, ie not fully charged. I have been away for a week, and this time I noted a 20 mile GOM before leaving; upon return, it was...

Has anybody mounted a bull bar on the front? I have to park in a neighborhood where the fellow parkers keep boxing me in. I have to push their cars ahead/back one or two feet just to commute home. This has happened often enough that I'd like to protect the front bumper and license plate with...

I don't normally go for bumper stickers and such, but I was reviewing custom license frames and bought one on a whim. As constructed, there is too much depth to the frame and the plate can rattle in the frame. The rear of the frame can damage paint. I installed vinyl bumpers on the back to...
