Which one do I disconnect? Negative Battery Cable on Hybrid

[mightysnopants]

I'm doing so mods where tis recommended that I disconnect the negative from the battery. I have a Hybrid. There are 3 places to disconnect. The green which look like the main negative cable. The Red Arrow points to something I don't know what that is. Or in back of it all looks like the main terminal block for the whole negative connection - The blue Arrow. Which one do I disconnect to be safe. The green one is easy enough to get to. I know very little about electronics other than shorting out on a vehicle is bad. Any advice would be helpful. Thanks.

I haven't looked at it, and can't see your whole pic, but it's going to be whatever removes ALL of it from that end of the battery.

read the manual, it tells you what to disconnect 12v wise and i think hybrid battery pack wise (if you have a hybrid)

Anyone have pictures of the ground location? Working on another project and would love a good ground there

I was able to reset some crash avoidance/sensor errors in my gas 4Runner by simply disconnecting the battery. Having the same issue in my hybrid now but disconnecting the battery did not do the trick. I’ve checked the 5 harnesses (parking sensor plus the center radar) and everything appears fine. In addition to the primary (green arrow in OP) I also pulled the orange tab on the rear passenger side thinking it disconnected power to the hybrid battery pack.

Any thoughts or ideas from the group? Is there something I missed still supplying power to the ECU? I let it sit for about an hour last time, trying overnight this evening.

i think you have to remove both cables from the 12v battery.


again if you read the manual it states if you remove the terminals

emphasis mine on the "s"


its on page 608 of the hv manual.
