Hi All! I have replaced the OEM hybrid battery with a Dorman one and now I cannot clear all of the error codes.
The one that seems to be taking out the power steering and cannot be reset is "C1546 Malfunction in hv ecu".
Does anyone know where is the hv ecu located? Inside the dashboard? I wonder if that is my problem or I am clearing the codes incorrectly. Any help with how to clear codes after hybrid battery replacement would be most appreciated!

Another new member!
Weclome to club lexus, glad you are here.

I like to hear your story, plz tell us all about it.
As much detail as you want.

How long you owned the car.
Mileage
What led to a battery replacement and did you have pending hybrid codes before battery replacement
Will the car drive or is it completely disabled
What is working properly and what is not working properly

The Hybrid control system connects to everything on the car so the more info you give the better members can help.
Cheers!

 

Why did you decide to replace the battery?
What error codes did you have before replacement?
Where did you buy a "new" battery?
Warranty?
Who did install it?
What codes do you have now?
