good VSA modulator-control unit, and recheck.  

NO: Replace the original wheel sensor (see WHEEL SENSOR REPLACEMENT ).  

DTC 12, 14, 16, 18: WHEEL SENSOR (ELECTRICAL NOISE/INTERMITTENT INTERRUPTION) 

1. Check the appropriate wheel sensor and magnetic encoder (see Fig. 35 ) (see WHEEL SENSOR 

INSPECTION ). 

Are they OK? 

YES: Go to step 2.

2. Disconnect the VSA control unit 47P connector.  

3. Check for continuity between the appropriate wheel sensor + B terminal and other wheel sensor + B 

terminals (see Fig. 36 and Fig. 37 ). 

Is there continuity? 

YES: Repair short in the wire between the appropriate wheel sensor and the other wheel 
sensor.  

NOTE:

If the ABS indicator comes on because of electrical noise, the indicator goes off 
when you test-drive the vehicle at 19 mph (30 km/h).

from the 16P DLC. Turn the ignition switch OFF, then turn it ON (II) again. Test-drive the 
vehicle. If the ABS indicator comes on and the same DTC is indicated, replace the 
appropriate wheel sensor. If after clearing the DTC and test driving the vehicle, the ABS 
indicator comes on and the same DTC is indicated, replace the VSA modulator-control unit 
(see VSA MODULATOR-CONTROL UNIT REMOVAL & INSTALLATION ).
