n. Using a digital multimeter, check for continuity between
the terminal 1 of connector B-009 and the terminal 2 of
connector B-054 to check if there is an open in the rear
right wheel speed sensor signal wire according to the
table below.
Standard Condition
a. Use X-431 3G diagnostic tester to clear the DTC.
b. Start the engine.
c. Drive the vehicle at 15 km/h or more, read the ABS control module assembly DTC again with X-431 3G
diagnostic tester.
d. Check if the same DTC is output.

Diagnosis Procedure
a. Turn ignition switch to LOCK.
b. Disconnect the negative battery cable.
c. Remove the ABS fuse EF-36 (10 A) from the engine compartment fuse and relay box.
d. Check if the fuse is blown.
a. Using a digital multimeter, measure the voltage between positive battery terminal and negative battery
terminal.
b. The battery voltage should be between 9 V and 16 V.
a. Turn ignition switch to LOCK.
b. Disconnect the negative battery cable.
c. Disconnect the ABS control module assembly connector E-085.
d. Check if the wire harnesses are worn, pierced, pinched or partially broken.
