I'm officially at a loss. I tested the relay and found it's model number. RELAY, SYSTEM VEHICLE. BATTERY & BATTERY CABLE (PRIUS (NHW20))....
Well fellas. I think I have progress. I bought a new ECU and after clearing the codes I went from 6 warning codes down to just 1: Scanner:...
I think you're right. I'm really crossing my fingers that this new ECU is my magic fix. I'm out of ideas after that.
If anyone is interested I didn't get hit by a bus. I'm waiting on my new control unit to come in. Probably thursday.
Does anyone know what's up with Toyota dealerships wanting $700 for the battery computer when it's selling for $50 online? Am I missing something?
Friend let me borrow a "better" scan tool and it threw up the same warnings but pointed out that my battery was only at 11.1v instead of the 12.4...
Well that's confusing because I had the 12v disconnected for quite a bit. I'll try and reborrow that scanner to clear the codes just in case. If...
I think I will go with an optima. I've used those in some EV vehicles I've helped build and they were top notch when lithium was too expensive.
Okay so I hooked up the donor vehicle and nothing went boom. Still had the same warning light and no contactor click. The battery finally got to...
This battery is taking forever to charge. I'm going to pipe in 12v from another vehicle and try it. I'm assuming I can attach the jumpers to the...
By "clearing codes" do you mean holding down the ODO button when powering on? I know that will clear the dash warnings but I don't know if it...
May just do that. Standby.
Yeah I noticed how slowly it was charging after a few minutes. I wish this 12 V battery would charge as quickly as the individual cells did on the...
Very sound advice. I've got a two amp charger so it may be 45 minutes to an hour before I get up to 12 V. I'll check back in but thank you guys so...
As much as this will solve one problem it may not solve my entire problem as much as I would like it too. I don't think having the HV lines arc...
I just took the battery completely out of the vehicle and I'm charging it with a three stage charger. I'll get it up to slightly over 12 V and...
Yes. Am I off on this one?
I may have just figured something out please let me know if I'm totally off-base. I couldn't get the relays to click from any 12 V sources...
I managed to test both relays with a 12v source and they work perfectly. I'm not sure how to test the precharge relay. Other than that the only...
I think everyone in this forum has a better grasp than I do, lol. Yes I have tried disconnecting the 12v battery for extended periods of time to...
