Hello. Everyone. I have Prius 2016. and when i bought my Prius, i couldn't add TSS-P option. and i tried to buy related TSS-P part(ECU, camera, radar, ETC.), and i wired as drawing. My Prius was detected attaching new TSS-P part, but start to show error message. So, i thought some problem was on my part or i had to make wrong wiring. So, firstly, i remove TSS-P part to go previous state. but my Prius had same error message even i remove every part. i tried to scan to use OBD plug. but i can't delete Error message and DTC. Have you tried prius attaching TSS? or did you see this kind of message? Please help me.
