to

If any issue found, please repair the circuit
accordingly.
Check the sensor for damage to the head/rib or
if there is any metallic contamination on the
sensor head/ tone wheel or any bearing wear
causing the signals to drop or causing an
erratic signal.
If any of the issues found, please clean the
sensor/tone wheel/bearing or replace if
damaged according to the procedure.
Point B

- If DTC is still active on the same corner,
proceed as described in Point A.
- If DTC switches to the opposite corner,
check for sensor damage, if none,
replace the sensor.
- If DTC turns off, continue as described in
Point B:
Point A
Turn the ignition off. Isolate the circuit by
disconnecting the ABS Module harness
connector and the WSS harness and
connector. Note: Use the wiring diagram as a
guide to follow the path of the circuit. Turn the
ignition on. Using a DVOM, measure the voltage,
resistance of all wheel speed to ABS module
circuits being tested at the component harness

Connect the diagnostic tool to the ABS control
unit, perform “ABS verification test” from the
standard procedure to initialize and calibrate
the module.
Point C
If the code is not active at the time customer
brought the vehicle to the dealer, please
perform “ABS intermittent condition test” from
the “standard procedure.”
If the conditions which set the WSS DTC are not
present (fault is not active) and cannot be
recreated via the “ABS Verification Test” or
“ABS Intermittent Condition Test” then no
repair/replacement of the wheel speed sensor
should occur.

24MY IDCM has integrity check feature enabled
as a part of cyber security requirement. During
this
integrity
check
monitoring,
any
noise/interference in Serial Programming
Interface (SPI) communication between Low
