DTC C0210/33 Rear Speed Sensor RH Circuit; DTC C0215/34 Rear Speed Sensor LH Circuit; DTC C1273/73 Low Output Signal of Rear Speed Sensor RH (Test Mode DTC); DTC C1274/74 Low Output Signal of Rear Speed Sensor LH (Test Mode DTC): Description

Refer to DTC C0200/31  and C0205/32 .

DTCs C1273/73 and C1274/74 can be deleted when the speed sensor sends a vehicle speed signal or the test mode ends. DTCs C1273/73 and C1274/74 are output only in the test mode.

DTC DETECTING CONDITION CHART

DTC No. DTC Detecting Condition Trouble Area
C0210/33 C0215/34 When any of the following is detected:
  1. At a vehicle speed of 6 mph (10 km/h) or more, an open or short in the sensor signal circuit continues for 1 second or more.
  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 wheels' 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.
  • Right rear and left rear speed sensor
