  2. Momentary interruption of the sensor signal from the abnormal wheel occurs 255 times or more.
  3. An open in the speed sensor signal circuit continues for 0.5 seconds or more.
  4. When the vehicle is driven in reverse at the speed of 1.8 mph (3 km/h) or more and 3 of the wheel sensors detect the reverse signal, the other sensor detects high frequency pulse 75 times while the engine switch is on (IG).
  5. At a vehicle speed of 6 mph (10 km/h) or more, the vehicle speed sensor output halves for 5 seconds.
  6. At a vehicle speed of 6 mph (10 km/h) or more, the direction of wheel rotation changes 7 times in 0.006 seconds while the engine switch is on (IG).
  7. At a vehicle speed of 18 mph (30 km/h) or more, one wheel direction is different from the other 3 wheels' for 1 second.
  8. At a vehicle speed of 60 mph (100 km/h), a reverse signal is output for 1 second or more.
  9. At a vehicle speed of 18 mph (30 km/h) or more, the rotation direction of the one of the wheels is not detected normally and the rotation direction of the other 3 wheels is not the same for 1 second.
  10. With the IG1 terminal voltage 9.5 V or more, the sensor power supply voltage decreases for 0.5 seconds or more.
  1. Right rear and left rear speed sensor

INSPECTION PROCEDURE

NOTICE:
When replacing the ABS and TRACTION actuator assembly, perform zero point calibration (Click here).

HINT:
Start the inspection from step 1 when using the intelligent tester and from step 3 when not using the intelligent tester.

1.CHECK HARNESS AND CONNECTOR (MOMENTARY INTERRUPTION)

  1. Using the intelligent tester, check for any momentary interruption in the wire harness and connector corresponding to a DTC (Click here).
