Fa-5 Relay Operation
Set voltmeter to 20V scale. Measure voltage between hydraulic relay Black/Red wire and ground. With key off, voltage should be 10 volts. With key on, voltage should be greater than zero volts. If voltage readings are correct, repair Black/Red wire from relay to hydraulic control unit. If voltage readings are not correct, go to Q-1 BRAKE ON-OFF SWITCH CHECK .
