DTC Detection

Conditions

Possible Cause

C003A-00

Right Rear Wheel
Speed Sensor

These DTCs occur
when any of the
following conditions is
met:
1. ABS control module

assembly detects
that the wheel
speed sensor signal
wire is short to
ground.

2. Wheel speed sensor

line is open.

3. ABS control module

assembly detects
that the wheel
speed sensor signal
wire is short to
power supply.

4. ABS control module

assembly detects
that the wheel
speed sensor power
supply wire is short
to ground.

5. Wheel speed sensor

signal is invalid.

 Wheel speed sensor signal wire is

connecting with the power supply wire
in reverse.

 Wheel speed sensor signal wire is

short to ground.

 Wheel speed sensor line is open,

connector is loose or broken.

 Wheel speed sensor signal wire is

short to power supply.

 Wheel speed sensor power supply

wire is short to ground.

 Sensor head or plug pin is damaged.
 Wheel speed sensor is interfered by

magnetic field outside (wheel or axle is
not demagnetized).

 Wheel speed sensor body is

malfunctioning.

 Ring gear is not installed, has teeth

missing, dirty, demagnetized or off
center.

 Clearance between sensor and ring

gear is excessive.

 Number of ring gear teeth is wrong.
 Tire size is not as specified.
 ABS control module assembly is

damaged.

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 rear right wheel speed sensor with X-431 3G

diagnostic tester.

c. Check if the data change of rear right wheel speed sensor matches the change of other wheel speed

sensors.

a. Remove the rear right hub assembly.
b. Check for foreign matter, missing teeth or damage on the rear right hub ring gear.
