I have a 2008 rx 400h with 225,000 miles on it. I was getting Maintenance Required light off and on for a month and had planned to take it in but this week there was also a message to check hybrid system. That went away after a day and the maintenance light came back solidly. I took it in to my repair shop today and they put 3 code readers on it but can’t solve the issue. The read out is U0009 and they think it might need a hybrid control unit and they told me to take it to the dealer for a better reading. Have any of you experienced this? And does the replacement unit have to be programmed by the dealer or can my repair shop do it. Thank you.

Does anyone have the part numbers for the 3 cables that make up the parking brake setup? Thanks.
