    Greetings from sunny Arizona! I have a dilemma that I need to solve on a 2011 Prius. My elderly father returned home after a 4-month Travel restriction from Europe ( he was basically stuck there) to a dead battery Prius - no surprise there. He Attempted to charge the battery by hooking up a charger to the battery directly...Impatient as he is, he also decided to hook up a small jumper to the front Jump Point (at the same time). Boom - The Prius was now dead. He did manage to blow the 125 DC Fuse ( Reverse Polarity ) that is located at the base of the fuse box...I replaced it, I bought a new rear battery - and now we have a Christmas Light show on the dash. The Prius will NOT go into READY mode. I can Force Start the motor/engine, but it has no power steering and all the warning lights are on. Techstream says that we have lost communication with the Power Steering Module and ABS Brake Module...However, I even swapped a different Power Steering Module and it still has no communication with the working module. No other codes are present, yet all lights stay on. Has anyone experienced this before?

    You need to check all fuses and/or fusible links. You likely have one or more blown.

    And this is the code I got the first time I scanned it using LAUNCH Pro. Right now the Prius actually starts in hybrid mode, and engine comes on. It goes in gear. Yellow Triangle is ON along with READY, Check Hybrid System, ABS, Brake, TCS - no more check engine light. Still no power steering at this time. Bringing up the Hybrid System in Techstream shows no communication with the ABS/Brake System

    What’s a “small jumper?”

    Another very recent long saga started the same way. Ended up getting sorted without too much expense. Different incidents might not have identical effects, but simple, patient, systematic checking and good observation tracked them down. Might be worthwhile to review that one to see how that looks.

    Part of the trick was not to be too spooked by other posters saying it was certain something expensive was fried and it wasn't worth fixing. Well, sure, that could happen ... that's what doing the simple patient checking and observation will tell you. In that case, it was nothing of the sort.

    I imagine a jump pack. Those portable batteries to jump start a car.

    First thing to check for when working on a no-comm (U codes) is powers and grounds to the affected modules. Since you had a jump start incident, I'd get a wiring diagram and test all the fuses and fusible links- beginning with those for EPS & ABS.
