DTC 15

Inspection Procedure: Code No. 15 Wheel Speed Sensor System:

COMMENT: This Diagnostic Trouble Code (DTC) is output when there is a malfunction (other than broken wire or short circuit) in any of the wheel speed sensor output signals while driving. The following can be considered as the cause of the wheel speed sensor output malfunction:
- Distortion of rotor or teeth missing.
- Low frequency noise interference when the sensor harness wire is broken.
- Noise interference in sensor signal.
- Sensor output signal is below the standard value or amplitude modulation is over the standard value. Using an oscilloscope to measure the wave shape of the wheel speed sensor output signal is very effective.
- Broken sensor harness.
- Poor connector connection.

PROBABLE CAUSE:
- Improper installation of the wheel speed sensor.
- Malfunction of the wheel speed sensor.
- Malfunction of the rotor.
- Malfunction of the wheel bearing.
- Malfunction of the wiring harness.
- Malfunction of the ABS-ECU.
