1. DTC 12, 14, 16, 18: Wheel Sensor (Electrical Noise/Intermittent Interruption) NOTE: If the ABS indicator comes on because of electrical noise, the indicator goes off when you test-drive the vehicle at 30 km/h (19 mph). Check the appropriate wheel sensor and magnetic encoder or pulser.
   DTC | Appropriate Wheel Sensor
   --- | ---
   12 | Right-front
   14 | Left-front
   16 | Right-rear
   18 | Left-rear
Are they OK?
YES | - | Go to Step 2 .
NO | - | Clean and reinstall or replace the appropriate wheel sensor or magnetic encoder or pulser.■
1. Disconnect the VSA control unit 47P connector. Check for continuity between the appropriate wheel sensor GND terminal and other wheel sensor GND terminals (see table).
   DTC | Appropriate Terminal | Other Terminals
   --- | --- | ---
   12 | FR-GND: No. 33 | No. 46 | No. 42 | No. 37
   14 | FL-GND: No. 46 | No. 33 | No. 42 | No. 37
   16 | RR-GND: No. 42 | No. 33 | No. 46 | No. 37
   18 | RL-GND: No. 37 | No. 33 | No. 46 | No. 42
Is there continuity?
YES | - | Repair short in the wire between the appropriate wheel sensor and the other wheel sensor.■
NO | - | Go to Step 4 .
1. Substitute a known-good wheel sensor for the appropriate wheel sensor.

Clear the DTC using the HDS. Disconnect the HDS from the 16P DLC. Turn the ignition switch OFF, then turn it ON (II) again. Test-drive the vehicle. Does the ABS indicator come on?
YES | - | Check for loose terminals in the VSA control unit 47P connector. If necessary, substitute a known-good VSA modulator-control unit, and recheck.■
NO | - | Replace the original wheel sensor. ■
