Re: Introducing OVMS for RAV4 EV

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 alone.

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

Re: Introducing OVMS for RAV4 EV

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

Re: Introducing OVMS for RAV4 EV

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 ...

Re: Introducing OVMS for RAV4 EV

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 short a...

Re: Introducing OVMS for RAV4 EV

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: https://www.mouser.com/P...

Re: Pictures from my onboard charger fuse replacement

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.

Re: Touchscreen of the Navigation System doe not work

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

Re: 2014 RAV4 EV won't charge

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, PM me for ...

Re: 2014 RAV4 EV won't charge

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 before: t...
