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. Turn ignition switch to LOCK.
b. Disconnect the negative battery cable.
c. Check rear right wheel speed sensor mounting bolt for looseness.
d. Check if excessive clearance exists between the installation position of rear right wheel speed sensor and 

rear hub ring gear.

e. Check the installation position of rear right wheel speed sensor for dirt.

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.
c. Check if the rear right hub assembly is securely installed.
