a. Turn ignition switch to LOCK.
b.  Disconnect the negative battery cable.
c. Disconnect the ABS control module assembly connector 

E-085.

d. Using a digital multimeter, check for continuity between 

ABS control module assembly terminal 13, 38 and body 
ground to check if the system ground circuit is normal 
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. Disconnect the front left wheel speed sensor connector E-060.
d. Check if the wire harnesses are worn, pierced, pinched or partially broken.
e. Look for broken, bent, protruded or corroded terminals.
f. Check if related connector pins are in good condition.

DTC Definitions

DTC Detection 

Conditions

Possible Cause

C0031-00

Left Front 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.
