I have a 2005 Prius. A few days ago while driving, I noticed the BRAKE light, ABS, VSC, and (!) light came on as I was driving on the freeway. Knowing this could be a potential problem, I took it to the Toyota dealership to get it diagnosed. I was suspecting the issue was with the brake actuator; However, it was replaced back in September 2016. Toyota said the issue was a faulty skid control ECU. I was given the codes C1300 (ABS ECU Malfunction) and C1364 (W/C Pressure Sensor). I requested the Freeze Frame Report, which listed a Detailed Freeze DTC 1027 under the C1300 code and a Detailed Freeze DTC 237 under the C1364 code. Does anyone know what these Freeze DTC codes mean? Also, Toyota said the replacement part number for the Skid Control ECU is 89540-4713. However, I can't seem to find that part on Ebay. Will using an ECU with part number 89540-47100 work in my car?
See @Texas Hybrid Batteries post, Skid Control ECU Issue (Resolved) | PriusChat Seems any Gen 2 will work for any year model car.
I am having the exact same issue and am wondering if the 47100 will replace the 47130 part. Thanks for asking! Ihope you solved your problem!
