Issue with electronic parking brake
A week ago, I got a light.message says the electronic parking is not working and to take the care for service. The car drives fine. The parking brake cannot be engaged or auto activated. We read the codes and it showed that the parking brake ECU cannot be contacted. I purchased a used module on ebay and it still says it cannot be read. I made an appointment at the Toyota dealer close by.
Do you think it has to be programmed to the car or is something else going on?

Leonrojo18, what happened with your parking brake issues? I've encountered the same thing and bought the module on eBay as well. When I installed it I had the blinking parking brake light on and the constant chiming so I disconnected it and am hoping you are going to tell me you had to have it programmed at the dealership. I'd hate to think I wasted $125 on the parking brake module. Any info you can give me would be greatly appreciated.

I fixed it myself using tech stream software and cable from amazon. I had to reprogram it after installation. There is an option in the software to reset the module because you will see an error code after you swap it out. before swapping, the error code said that it could not communicate with the parking brake module. After the module switch, it was a different code and I was able to reset the module. After resetting, there is a procedure to set the zero point. You can Google all these procedures. You could do all this or take it to the dealer for programming.

I cannot thank you enough for your most helpful response. I will go to amazon and order the tech stream software and cable. I don't have a scanner but can probably get my hands on one if I need one. Is there a certain software number or model that you ordered? And I agree with roadfrog above, this kind of info is so important to us do it yourselfers. Ive had this module for months just waiting for someone who had a similar experience to post the proper fix. Kudos to you my friend. I will anxiously await your response.

Procedure is described with pictures in a factory manual (as i said previously). Not in a 'user' manual...
Of course the unit needs to be paired, calibrated, then parking shoe bedding-in procedure (somewhat automated, mistakenly called 'zero point') must be performed.
