I had the brake accumulator pump replaced under the Toyota TSB. In doing this job the inverter needed to removed. Now I seem to be getting poorer MPG in city driving (stop & go). I'm wondering if taking the inverter out (with all the necessary connections) and putting it back in place would reset or somehow affect gas mileage. I'm noticing now the high voltage battery is usually charged (all green lines). Anybody have any thoughts on this? Thanks - Marvin
Marvin, I suspect that when the work was done it was a standard safety precaution for the car to be electrically "dead," that is both the high voltage and 12V systems were disconnected. When the 12V system is disconnected, the HSD computers loose some of operating data that they have "learned," really only stored for use. I've read that it takes 2-3 weeks for the computer to regain the data. Here's a thread on this... I can't say I really understand it: http://priuschat.com/forums/gen-ii-...on/45271-how-what-does-prius-cpu-s-learn.html For the record was this work covered by any warranty? Does your paperwork say how much the two repairs would have cost?
Rokeby, Thanks for your reply. Very interesting. RE: your questions: the work was covered under warranty. My paperwork does not show a final cost, but I know the brake accumulator assembly costs $2,136 alone, plus labor. And the job is estimated to be 4.5-5 hours. So I estimating about $500 in labor costs. Marvinh
Found an interesting link with good pictures on brake actuator replacement that I had not seen before. http://priuschat.com/forums/gen-ii-...7-brake-actuator-replacement-in-pictures.html I know the brake accumulator assembly costs $2,136 alone I wonder what my car would cost if everything was bought by dealer cost individually, ouch.
Yeah, it's rude but someone has to pay for boxes of cardboard and bubble wrap, oh and that lovely spare parts desk with the parts getters behind it.
Hi Marvin, Curious, was the posted labor rate $200 an hour? (Seems high ... I would have expected $90 - $100.)
Tom - Now that you mention it, I haven't seen the posted labor rate. I was just estimating the total labor cost, but you are probably closer to the rate than I am. In any case, I went back and edited my response in my previous post to $500 for labor. Thanks - Marvin
The dealer left it ON for a while, they drained the battery somewhat, the weather's colder. All perfectly normal. If they screwed something up it would most likely become obvious soon.
