INSPECTION PROCEDURE
1. CHECK CONNECTOR
1. Turn ignition switch OFF, disconnect the ABS actuator and electric unit (control unit) connector, and check
terminal for deformation, disconnection, looseness, and so on. If there is a malfunction, repair or replace
the terminal.
2. Connect connectors securely and perform self-diagnosis again.
Is above displayed on self-diagnosis display?
YES >> Print out the self-diagnostic results and refer to LAN-49, "CAN System Specification Chart" .
NO >> Connector terminal connector is loose, damaged, open or shorted.

REMOVAL
Be careful of the following:
CAUTION:
When removing the wheel sensor, do not rotate it if possible, and do not forcibly pull the wheel sensor
harness.
INSTALLATION
Note the following, and tighten bolts to the specified torque.
Check the inside of the wheel sensor mounting hole for foreign materials, the rotor surface for iron chips
and other foreign materials. Clean both the wheel sensor mounting hole and the rotor surface before
installation. Replace the wheel sensor if there is any non-standard condition.
Completely push in rubber clamp of strut bracket and body bracket until they lock when installing front
wheel sensor so that the wheel sensor harness will not be twisted. Install grommet groove onto bracket
with yellow line on the harness facing bracket opening (mounting hole). There should be no twists in the
harness when installed.
When installing the rear sensor, securely install the harness mount of the rear suspension member so that
the wheel sensor harness is not twisted. In addition, there should be no twists in the harness when
installed.
