Had a couple 2006 Toyotas in the past week , one a Sequoia and the other a Sienna. ABS codes traced to bad actuators. Everything , pump, ecu, and hcu together is an integrated $2k assembly. What's the chance a used one is going to be good ?
Sometimes you get them with an ABS pump failure code,You can communicate with the module , but can't command the pump on with the scan tool. You check power and grounds check good and you unplug the pump feed connector from the module part and with a power probe and jump power and ground to the pump motor connector and it works, so you know the problem has got to be internally in the module part.
