This relay supplies power to each ABS solenoid. After the ignition switch is turned ON, if the initial
check is OK, the relay goes on.
DTC No. Diagnostic Trouble Code Detecting Condition

Fail safe function: If trouble occurs in the control (solenoid) relay circuit, the ECU cuts off current to
the ABS control (solenoid) relay and prohibits ABS control.
DIAGNOSTIC CHART
Check voltage of ABS control relay connector.
Check continuity between relay and actuator
and ECU.
Check ABS control relay.
Check for open and short in harness and con–
nector between relay and ECU.
If the same code is still output after the diagnostic trouble code is deleted, check the contact condition
of each connection.
If the connections are normal, the ECU may be defective.
