The Electrified Garage folks should definitely be able to help you with your charger issue. If it is a fuse replacement, that should be an easy repair. If you want to repurpose a gen 1 Model S OBC, you'll either need to flash the RAV-specific firmware onto it, or transfer over the control...

Glad to see you were able to get CAN working, as well as ethernet too. I'm curious about the screenshot you show above: is this taken from being connected to your RAV4? If so, there are several CAN ID's I'm surprised to see, because they haven't been present in the CAN stream of other RAV4's...

Have you noticed if any older Leafs have been able to charge at these newer stations? If so, that would tend to rule out the chargers being the problem. Most likely the chargers have been updated to a newer version of the CHAdeMO standard, and that's causing communication issues with Jdemo...

Curious: what brand/model fuses did you use for replacements the first time?

It is not necessary to evacuate the refrigerant lines when removing/installing the OBC; there is sufficient play in the hoses to wiggle things around.

It's possible the replacement charger (presumably used from a wrecked Model S) itself may have been defective, and thus unable to communicate with the powertrain software. Or the charger unit may have been setup as the slave module in a two-charger configuration that was an option on the Model...

Your problem is most likely a failing onboard charger (OBC). The is on the Telsa-side of things, so unfortunately your local Toyota dealer will only have the software to check for codes on the Toyota side, which is usually a generic P312F code (that simply means the Tesla gateway has requested...

Thanks for sharing your write-up, and glad to hear everything is now working. Vlad (Alflash) is indeed a great asset to this community, and I wish him and all Ukrainians health and safety in these difficult times. Regarding your questions about the replacement Model S charger: as I mentioned...

Odds are you likely don't need to adjust the parking brake lever to cable adjuster (to take up cable stretch). Remove the rear wheels and re-install the lug nuts to keep the brake rotor in position. There is supposed to be a shoe adjusting service plug that can be removed to access the shoe...

The BMS controls the contactors, so likely it's choosing not to do so based on the pack voltage being too low. However since you've done a bit of work on the car, it could be possible that something else is causing the contactors not to close, like a break in the high voltage interlock circuit...

Al- Personal preference here, but you might consider using some small pieces of heat shrink over the leads soldered to the header pins; there's not much clearance between connections and I'd argue that a shrink sleeve (or some Kapton tape) is better protection against a short than mere potting...

I have the benefit of having these connectors sitting on my desk, next to a very good LED magnifier/light :D

Almost there, Al: the -0201 connector was correct originally, as its view/pin numbering is from the back/wire side.

Al- I am interpreting your description of the connector (-9201) that plugs into the harness "from the wire side" to mean looking at the back side of the connector where you will solder leads to; if that's the case, then your pin numbers needed to be mirrored to match the gateway connector (which...

The Tesla and Toyota CAN networks are terminated at both ends. A brief scan through the OVMS documentation seems to indicate that there are no termination resistors in the unit, so it should connect without any problems. The max length for a CAN stub is 1 meter, but I recommend keeping it as...

For anyone interested in making their own cable: The male receptacle (e.g. on the gateway PCB) is only available as a PCB mount, so one has to solder flying leads to the pins (i.e. there is no option for male crimp pins). There are options for either straight or right angle...

Dave, thanks for the fantastic writeup! Unfortunately I'm not seeing any pictures included in your posts (but google album looks great). Perhaps it would be worth putting the text and pics together in a pdf and posting that, which also future-proofs it from any problems with image hosting servers.

Does not work as in blank display, or display works but not the touchscreen functionality?

Yikes, 2.85 V per cell is pretty low :o Unfortunately, the only info given in the service manual for fault code CHG_f002 is to replace the charger unit. If indeed the internal HV fuses were blown, other components may have been damaged. I have a spare working charger if you're interested...

Were the charger fuses indeed bad? Unfortunately diagnostics from the Toyota side of things yield almost nothing of use: the P312F code simply means that the Tesla side of things has a problem, and the gateway is requesting the malfunction indicator lamp (MIL). One thing that has bitten me...
