a. Connect X-431 3G diagnostic tester (the latest software) to Data Link Connector (DLC).
b. Drive the vehicle straight ahead, and read the data stream of each wheel speed sensor with X-431 3G
diagnostic tester.
c. Check if the data change of each wheel speed sensor matches the change of other wheel speed sensors.
a. Remove the hub assembly.
b. Check for foreign matter, missing teeth or damage on the hub ring gear.
c. Check if the hub assembly is securely installed.
a. Turn ignition switch to LOCK.
b. Disconnect the negative battery cable.
c. Disconnect the ABS control module assembly connector
E-085.
d. Disconnect the front left wheel speed sensor connector
E-060 and front right wheel speed sensor connector
E-036.
e. Disconnect the rear left wheel speed sensor connector
B-029 and rear right wheel speed sensor connector
B-009.
f. Using a digital multimeter, check for continuity between
the terminal 8 of connector E-085 and the terminal 2 of
connector E-060 to check if there is an open in the front
left wheel speed sensor signal wire according to the table
below.
