Application
Description
(When connector is removed)
Replace the hydraulic modulator.
Check each valve by using SCANER's solenoid valve
overriding function.
Check connection of connector and terminals in the
ECU hydraulic modulator.
Check terminals for open or short.
(When connector is removed)
Replace the hydraulic modulator.
Check solenoid internal resistance of the prime(ASV)
valve and pilot valve(USV) : 8.04 - 9.04 W
