I have a 2011 Toyota Prius. C2303 C2304 C2305 C2306 I checked the wiring, replaced the sensor on the transmission, replaced the integration relay, and replaced the relay. The only thing left is the transmission control module. How do I replace it? If I just plug it in, the immobilizer light flashes.
It's part of the theft-protection system, so it needs to be introduced properly to the module that recognizes your key. I'm not sure any of us do that often enough to remember the steps offhand; it's the kind of thing I'd go straight to the repair manual for, to avoid possibly trying to follow mistaken instructions from the internet.
