Hey Everyone,

Just picked up a CPO 2013 RXh with 53K and would like to clear out all of the old info in the ECU from the previous owners driving style and such.
Normally this can be accomplished by disconnecting the battery for a period of time.
Can this be accomplished by disconnecting the starting battery, or would the traction battery need to be disconnected as well.
New to the Hybrid world.

Thanks,
Brian

I disconnected the starting battery for about 2 hours this morning, It did reset average mpg and those settings, but the radio settings and clock and such remained, so don't think I got a full reset. I would normally touch the 2 leads together to drain any caps and such, but just not sure how the traction battery is tied into the system. Going to have to figure something else out, or just break down and purchase the cable for the Techstream software and do it through the laptop.
