I've been working on my 2007 Camry Hybrid brake error issue for a few days and learned a few things that may help others. I will end up putting in a different unit, but I'm now pretty confident that I've found the issue. The first symptom was the actuator motor running frequently, I assumed this was a leaky accumulator. After some bleeding and resetting, this issue disappeared, but I acquired a C1345 and C1368 (linear valve offset incomplete/failing). It is completely unable to complete the linear valve offset teach. I was able to watch the pressures of the wheel circuits during the valve teach and saw the RL circuit not responding well. I tried some active tests on that circuit (RL: SLARL valve) and found that it was not sealing well: at 0V it would leak pressure and cause the wheel circuit to build pressure. This is likely the cause of the frequent pump running. I zero'd down the accumulator with the pump relays removed, disconnected that brake line (2nd from the drivers side), loosened the accumulator circuit (empty bleeder valve on block), disconnected the line from the reservoir, and flushed it with brake parts cleaner and compressed air while actuating it's valves in an attempt to clear whatever was preventing sealing. This seamed successful. After reconnecting the lines and flushing that circuit (and accumulator) that circuit sealed up better and would not start building up pressure until about .42 Amps (the other circuits start building pressure around .45 to .5 Amps). The accumulator pressure was also much more behaved, holding pressure for 24 hours, and not even needing to run the next day when I turned the car on. The valve offset still fails, but I got closer. Running some more tests on the two rear circuits (SLARR and SLARL), I found that the RR side would build pressure in a very square wave with the amplitude dependent on the actuator current. The failing RL side was much more curved, taking longer to get to pressure and going to a much higher pressure. I'm suspecting that the valve is not moving freely enough for the teach routine. Is there much of a possibility that the error is in the coils or wheel cylinder? I've considered getting a brake line plug to eliminate the wheel cylinder from the equation.
