Hi All, I have prius 2011, Gen 2 and I am seeing an ABS warning light on in the dash. Scanner showed error code C1391 which indicates "Abnormal leak in Accumulator". I can still hear the sound of ABS pump which is trying to pump the oil in accumulator but doesn't get pressure build up, that's why it probably runs longer than it does. And sometimes keeps running to around 2 mins. 1. Can I assume that the ABS motor is not faulty? 2. I want to replace the accumulator ONLY ( from another ABS unit. Would it work? Has anyone else have done the same? Please share your expert opinion. Thanks.
