   If the freeze data/on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the Freeze data/on-board snapshot.

2. Wheel speed sensor installation check

   - 1. Turn the vehicle to the OFF (LOCK) mode.

   - 2. Check that the appropriate wheel speed sensor is properly mounted.

   DTC	Appropriate Wheel Speed Sensor
   12-11	Right-front
   14-11	Left-front
   16-11	Right-rear
   18-11	Left-rear

   Is the wheel speed sensor installation OK?

   Go to step 3.

   NO 

   Reinstall the wheel speed sensor - Refer to:

   Wheel Speed Sensor Removal and Installation (2014 2015 2016) , or

   Wheel Speed Sensor Removal and Installation (2017 2018 2019 2020), .

   and recheck its mounting position, then go to step 1.

3. Wheel speed sensor check (substitution)

   - 1. Substitute a known-good wheel speed sensor.  Refer to:

   Wheel Speed Sensor Removal and Installation (2014 2015 2016) , or

   Wheel Speed Sensor Removal and Installation (2017 2018 2019 2020), .

   DTC	Appropriate Wheel Speed Sensor
   12-11	Right-front
   14-11	Left-front
   16-11	Right-rear
   18-11	Left-rear

   - 2. Turn the vehicle to the ON mode.

   - 3. Clear the DTC with the HDS.

   - 4. Turn the vehicle to the OFF (LOCK) mode.

   - 5. Test-drive the vehicle for 2 minutes or more.

   NOTE:  Drive the vehicle on the road, not on a lift.

   - 6. Check for DTCs with the HDS.

   DTC Description	DTC	Freeze Frame
   12-11 Right-Front Wheel Speed Sensor Electrical Noise or Intermittent Interruption
   14-11 Left-Front Wheel Speed Sensor Electrical Noise or Intermittent Interruption

   18-11 Left-Rear Wheel Speed Sensor Electrical Noise or Intermittent Interruption

   Is DTC 12-11, 14-11, 16-11, or 18-11 indicated?

   YES 

   Go to step 4.

   NO 

   Replace the original wheel speed sensor - Refer to:

   Wheel Speed Sensor Removal and Installation (2014 2015 2016) , or

   Wheel Speed Sensor Removal and Installation (2017 2018 2019 2020), .

4. Magnetic encoder check

   - 1. Turn the vehicle to the OFF (LOCK) mode.

   - 2. Inspect the appropriate magnetic encoder for damage, debris, and correct installation.

   DTC	Appropriate Magnetic Encoder	Note
   12-11	Right-front	Remove the driveshaft outboard joint from the appropriate wheel hub .
   14-11	Left-front
   16-11	Right-rear	Remove the hub bearing unit - Refer to: Rear Knuckle/Hub Bearing Unit Removal and Installation (2014 2015 2016), or Rear Knuckle/Hub Bearing Unit Removal and Installation (2017 2018 2019 2020) .
   18-11	Left-rear

   Is the magnetic encoder surface OK?

   YES 

   Go to step 5.

   NO 

   Clean the debris from the appropriate magnetic encoder surface on the wheel bearing or the hub bearing unit. If the debris cannot be removed or the encoder is damaged, replace the appropriate wheel bearing or the hub bearing unit - Refer to:
