Separate names with a comma.
Any other wire in the harness, or any other wire, period?
With the ignition key OFF and out of the ignition switch, disconnect the HV ECU harness connectors as well as the inverter harness connectors, and...
A competent technician who has done the job before can do it in about an hour and a half. See above. I said "removing and replacing the...
The code indicates a short to power (B+ meams battery positive), not a short to ground. It's a communication line, with pulsed signals. You are...
15 hours of labor? It would be difficult for even an inexperienced technician to spend more than three hours removing and replacing the battery...
bwilson4web is probably trying to express open circuit voltage, i.e. voltage with no load. "Static voltage" would actually be the voltage...
That's correct. But in my opinion, the great majority of P3100 codes are not caused by a faulty HV ECU.
Not necessarily. Toyota is more liberal on out-of-warranty goodwill repairs than most automakers, and they can be particularly liberal with...
Despite what you may read in the forum archives, P3125 does not necessarily indicate a faulty inverter. Your vehicle's HV ECU will have recorded...
Some information codes associated with P3100 indicate an internal ECU problem. Some do not. P3100 can set for many reasons. The repair manual...
A failed inverter water pump does not always cause the inverter to be damaged. Folks sometimes recommend replacement of both items because they...
It's not possible to say for sure until you retrieve the codes that triggered the warning lights. If the vehicle already had codes stored, you'll...
Not always. The voltage drop often occurs between battery terminal and voltage sensing wire, rather than between battery terminal and bus bar. The...
I didn't state that drewd's HV leak "would have induced other problems". You did. I clearly called that statement into question, as the root cause...
I don't have enough information yet. That's why I asked the question. I'm well aware of those, thanks. My question concerns your assertion...
Why do you say that?
Did the technician clear codes after reading them, and verify that P3125 came back? Re: P3000 - your HV battery may be at fault, but it's hard to...
You have nothing to apologize for. Addressing the original poster, forum member adric22 posted a video that documented a service procedure for a...
Questioning, yes. There is nothing wrong with that. Attacking, no. I didn't agree with adric22's conclusions, nor with the logic. I think it's...
P0110 and P0100 codes can be set if someone disconnects the MAF sensor when its circuit is energized.
