Description
The motor relay drives the pump motor based on a signal from the skid control ecu.
Wiring diagram
Refer to dtc c0273/13, c0274/14, c1361/91 (see page bc-79).

Hint:
A momentary interruption (open circuit) in the connectors
and/or wire harness between the sensors and ecus can
be detected by using the ecu data list function of an
intelligent tester.
Turn the ignition switch off and connect the
