    Errors After Inverter control board replacement and problems with re-flash.

    I ran my LDU with no half-shaft installed, and the lower ball joints disconnected. I seem to get the power steering warning whenever the HV contactors open; the DC-DC Converter goes offline, no support for the 12v system, and the PS system is the first to issue a "low voltage" warning. I bet...

    I dbl-checked, and pins 7 & 8 on the LDU are the HVIL lines, yes: Source: 2014 RAV4 EV electrical diagram (Tesla parts only)

    Well, HVIL faults are relatively easy to track down. The High Voltage Interlock Loop is a series of (60ohms * n) resistors. If any connector that carries HV is not fully mated, the BMS sees the wrong loop resistance and refuses to close the contactors. That's actually one of the easier things...

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

    I'm installing a LDU rotor temp monitor, for data collection purposes. I don't have a good idea of how coolant delete Tesla firmware can make the rotor dissipate heat any faster; all it can do is limit the duration of certain power levels, and there's still no temperature sensing other than the...

    Thanks. I have crossposted this info to a long-running LDU repair thread over at teslamotors.com, where a lot of discussion about weep holes, coolant delete mods, etc. have been going on. Mostly DIY folks in that thread, so the ability to ship you only the part they can't DIY is a real boon...

    You've convinced me, I guess. I am gearing up to provide 1.1.42 license keys. I'll do a separate thread for that, in about two weeks.

    Thank you for that. Do you provide that service ala carte, ie if a customer sends you a bare stator/case (stripped), do you offer to restore its iso resistance? Or, is this service only available as part of a larger LDU refurbishment? If you prefer to discuss this in a . . . less...

    Matt, can you elaborate on the service ReVolt provides to restore proper isolation resistance to the LDU? Or point me to a resource that describes your service?

    1) He's in a very different timezone (Odesa) than B.C., so you'll need careful coordination. 2) His screenshot link shows that, if you're using TPD 1.1.46, you (should) have the firmware: Maybe double-check?

    Really good info there, Vlad :)

    Errors After Inverter control board replacement and problems with re-flash.

    Remember: TPD, when used legally, connects to Toyota for firmware files. Your version may not be legal, and you have what you have. Or, you may need to pay Toyota USD$25 for a 48-hour subscription, in order to allow TPD to obtain files. IDK, I've never explored this, as I haven't had to flash...

    Errors After Inverter control board replacement and problems with re-flash.

    The Toyota service manual specifies to always support the 12v system with their GR8 (00002-MCGR8) device while programming. It's a fancy battery charger, yes. From T-SB-0043-13: That particular TSB is very Techstream-centric, but it eventually has you fire up TPD anyway to do the actual...

    “Charging Malfunction- check external power supply”

    Following on to this, there's a diagnostic socket at the Tesla Gateway module, located at the left rear of the cargo area, behind a plastic panel. It's user-accessible without tools. To use this socket, you need both a special cable, and special software. The software is kind of crap, but it's...

    “Charging Malfunction- check external power supply”

    You didn't provide any info on which EVSE you're using at home, or your home circuit's capacity. Matt gave good advice above. If possible change one variable: charge somewhere else. Using your Toyota-supplied 120v EVSE, or someone else's EVSE (anyone's, or public). Symptom change...

    Help replacing a coolant pump

    The Toyota side "remembers" that the Tesla side requested a MIL, and if the Tesla side stops requesting MIL, the Toyota side will still light it for anywhere from 3-5 cycles of the car. I thought it was always 5, but twice I've seen the MIL clear off the IC in 3 cycles, so [shrug]. IDK what's...

    Welcome! You are operating in territory where few have gone. Only alflash and QC Charge (who no longer is on this forum, he now hides from his past in a private/gated FB group) could answer your questions from experience. I believe that alflash ran into a situation with an OBC from a Model S...

    Longer Range Battery / Extra battery

    Bear in mind that a 40a circuit will only support 32a continuous, per NEC ("code"). Be sure and configure your new EVSE accordingly. The RAV4 EV will theoretically draw 40a continuous if you let it (mine tops out at ~38.2a usually). Don't make the mistake of configuring your EVSE to allow 40a...

    LDU rotor cooling bypass ("Coolant Delete") modification

    The tube has been pressed out and AFAIK nobody has an explanation for that circlip: why is it there, what did it do? Howard considered that pressing the tube out and installing a second plug there would be simpler for home DIYers but after seeing the galling that occurs when it's pressed out...

    LDU rotor cooling bypass ("Coolant Delete") modification

    1) No, 2.170" is the final oversize of .005", which = 55.12mm. Another person used 55.18mm which is an awful lot of interference fit on an aluminum casting of this size, but I was convinced to try 55.07mm first (.003") and that was not enough for a truly tight fit IMO, and then I had 55.12mm...
