    Looking for a mobile mechanic

    Have you tried restarting the car since this incident? With your foot on the brake, cycle power on then off 5 times in a row (press the ignition switch about every 2 seconds, you don't need to wait for the system to fully boot up each time). Leave the car on for the last cycle. This will...

    bad battery repair

    I remotely diagnosed this vehicle in June; there is nothing wrong with the charger, but rather the charge power limit is at 0 kW because there are multiple under-voltage bricks:

    Any reason for sudden battery health drop?

    If 12V battery power is interrupted, as it may have been done at your dealership, the driving efficiency is reset to a default value of 3.5 miles/kWhr. This value multiplied by the charge available in the battery pack will then be shown as the range on the GOM. In your case, 118/3.5=33.7...

    Another DOA Rav, time to troubleshoot- seems OBC fuses are fine ;-(

    GV200PA-1 is the part # I ordered directly from Gigavac in 2019; I replaced both OE contactors and have had zero problems since then. It was pretty much a direct swap in replacement.

    12V battery recharged, but RAV4 dead (won't even unlock door with remote key) - ???

    Usually when 12V power is interrupted, the brake booster pump will turn on for a few seconds when power is re-applied, and will definite draw more than 10A. Let the pump build pressure and shut off; the navigation unit will also draw power for a minute or so while it reboots. See what your...

    OK to drive with BMS_f038 code?

    You're on borrowed time; contactors will not get better, only worse. After getting that error code, I got about 5 short trips out of my RAV4 before the contactors completely failed and left me stranded. Replacing the contactors isn't that hard, about on par with replacing OBC fuses. However...

    Asking price? Is the charger the only issue?

    LDU rotor cooling bypass ("Coolant Delete") modification

    Unless I have a fresh o-ring (not really possible in this instance), I always add a bit of RTV as a backup sealer. I usually use Permatex Mega-black for almost everything. Alex from QC Charge recommends a quick setting version, see and then skip ahead to 41:58 for manifold installation.

    FS: 2012 RAV4 SF South Bay / San Jose Area

    The HV isolation resistance is measured by the BMS. I don't know the specifics of how Tesla does it, but other systems I've worked with use a divider network of resistors across the HV DC, with the middle tied to chassis ground; a crude layout is: (HV+)-R1-R2-gnd-R3-R4-(HV-). R1 and R4 are on...

    Way, indeed :) I was honestly surprised, but the CAN data doesn't lie. I'd be happy to walk you through what I did if you'd like to repeat my experiment, and see what results you get.

    FS: 2012 RAV4 SF South Bay / San Jose Area

    FYI - I recently did an experiment where I placed a resistor between one of the HV leads and chassis ground, to simulate degradation of the HV isolation. I was surprised that it took a value <500k ohms to see any response from the system (by monitoring CAN data), and even then the system...

    My turn for the Check EV message

    Where are you located? Do you have a price in mind for your RAV as-is?

    Traction Motor Blues and Extended Warranty "Extension"

    Congratulations on being able to get a replacement motor installed. By any chance does the repair order show the part # of the replacement motor? I think we'd all be curious to see if it's the latest revision with the coolant bypass.

    2013 Toyota EV Error Code BMS F063

    BMS_f063 is a fault with the pre-charge circuit. If this is the only fault shown, the remedy per the service manual is 'replace high voltage battery pack'. Without further diagnostics, it's impossible to know if the fix could be a replaceable part, although in all likelihood it would at least...

    $3000 Rav4EV project. BMS codes inside

    The seller indicates they are selling RAV4 EV modules, as both sizes/formats are listed ( https://jag35.com/products/toyota-rav4-battery-modules-by-tesla ) . But the hassle of swapping in unknown modules into a case that already has damage is probably a far greater cost and effort than just...

    Bay Area repair shop that can still work on RAV4EV?

    Was there coolant on the original sensor when you replaced it? If coolant found its way into the inverter, it may be possible for the speed sensor signal to be corrupted.

    $3000 Rav4EV project. BMS codes inside

    The battery voltage is shown as 241 V - this means the average cell voltage is about 2.6 V, and most likely many bricks are well below that. This pack is likely irrecoverable/permanently damaged. Was this vehicle flooded? The rust/grease seen on the speed sensor is more than typical for a...

    My turn for the Check EV message

    The 'Check EV' warning in the instrument cluster is based on a message sent from the Tesla gateway in the cargo area (inside left rear access panel) to the Toyota side of things. There is nothing on the Toyota side that would cause that message, and reading fault codes through the OBDII port...

    My turn for the Check EV message

    The item that caught my attention was stating that the hazard lights wouldn't work; this particular circuit involves no computers, just a common flasher module. This makes me think you have a low voltage power problem, either something intermittent with the 12V feed or with a ground. With the...

    Is anyone interested in selling their car?

    What was your offer? Carvana and Carmax are offering about $6k for my RAV4 with 80k miles; that's a low enough offer it's worth holding onto.
