SERVICE TIP:
Got an ABS DTC 51 (motor lock) or an ABS DTC 53 (motor stuck ON)? Although the S/M tells you to replace the ABS modulator unit if, during your test-drive, the ABS indicator comes back on and the DTC sets, don't replace the unit just yet. First try inspecting and cleaning the pump motor ground. A poor ground can also cause these DTCs to set.
