I’m dealing with a couple of codes on my 2006 Prius—C1319 and C1256. It started after I had the car lifted to fix a park motor issue. The brakes feel super stiff now, almost like manual brakes, but no warning lights are showing up. Anyone know what might be causing this? Any advice would be great.
What do you mean by ‘lifted’? Did you do anything specific to fix the motor? I’ve had parking motor problems before, and it turned out to be a bad 12V battery. Worth checking that out.

I had the car up on jack stands to work on it, and I’ve ruled out the 12V battery since that’s been replaced recently. All warning lights come on during ignition, so I think the lights are fine. The PAWL motor issue was because of a bad connection after sitting in a garage too long, but I’ve fixed that now.

Wait, what’s a PAWL motor? Is that the same as the parking motor or something different?

Yeah, it’s the motor that engages the parking mechanism. Mine had some corroded connections that I fixed, so that issue is gone, but now the brakes are acting up.
Those codes… Have you looked them up in the repair manual yet? C1319 has to do with the brake stroke simulator, which might explain why your brakes feel weird. And C1256 is related to low pressure in the brake accumulator. Maybe start by checking those systems.

Unfortunately, I only have a Chilton manual, which isn’t very helpful. I pulled the codes with a VXdiag reader. I got the C1319 a day after fixing the motor and the C1256 came up a couple of days later. I’ve checked the battery connections and the fuses, but I’m not seeing anything obvious.
@Harmon
You can find the official Toyota repair manual online. It’s much better than Chilton for these specific codes.
C1319 is a changeover solenoid issue, and that’s in the brake stroke simulator. It could be causing your pedal to feel stiff. You might want to check the circuit to see if it’s working right. Also, with C1256 being low accumulator pressure, I’d suggest checking your brake system pressure. Maybe clean the codes and see if they pop up again?
@Clovis
I tried wiping the codes, but they came back. I’m not sure how to check for subcodes with my current software, but I’m going to try and get more info. Thanks for the suggestion!
@Clovis
With Techstream, you should be able to pull subcodes from the freeze frame data. If you see a little snowflake icon next to the DTC, click on it and it’ll show you more details. That might help narrow things down.
@Clovis
Awesome! I’ll check that out. I’ve been struggling to figure out how to pull the subcodes, so this helps a lot.
I’ve had something similar before, and it turned out to be the brake stroke simulator. I replaced it, and my brakes went back to normal. If your brakes feel like they’re getting stiffer, that could be it.
@Hazel
Yeah, the brakes do feel super stiff. I’ll look into that. Thanks for the tip!
It could also be a pressure issue in the accumulator if the C1256 code keeps coming back. You might need to replace that part if it’s not holding pressure right.

I’ve heard that can happen, but I’m hoping it’s not that serious. I’ll keep an eye on it and see if it gets worse.
