DESCRIPTION
The speed sensors detect the wheel speeds and send appropriate signals to the skid control ECU.Speed sensor rotors have rows of alternating N and S magnetic poles, and their magnetic fields change as the rotors turn.The speed sensors detect those magnetic changes and send pulse signals to the skid control ECU. The ECU monitors the wheel speeds through these pulse signals to control the ABS control system.DTCs C1271/71, C1272/72, C1275/75 and C1276/76 can be deleted when the speed sensor sends a vehicle speed signal or the test mode ends. DTCs C1271/71, C1272/72, C1275/75/75 and C1276/76 are output only in the test mode.
DTC No.

INSPECTION PROCEDURE
- NOTICE:
- Check the speed sensor signal in test mode after cleaning or replacement (RAV4_ACA30 RM000000ONN02FX.html).
1.CHECK HARNESS AND CONNECTOR (MOMENTARY INTERRUPTION) |
Using the Data List of the intelligent tester, check for any momentary interruption in the wire harness and connector corresponding to a DTC (RAV4_ACA30 RM000000XHS04PX.html).
Skid control ECUTester Display
| Measurement Item/Range
| Normal Condition
| Diagnostic Notes
|
FR Speed Open
| Front speed sensor RH open detection/ ERROR or NORMAL
| NORMAL
| -
|
FL Speed Open
| Front speed sensor LH open detection/ ERROR or NORMAL
| NORMAL
| -
|
- OK:
- NORMAL (There are no momentary interruptions).
- HINT:
- Perform the above inspection before removing the sensor and connector.
| CHECK AND REPAIR HARNESS AND CONNECTOR (SPEED SENSOR CIRCUIT) |
|
|
2.READ VALUE USING INTELLIGENT TESTER (FRONT SPEED SENSOR) |
Check the Data List for proper functioning of the front speed sensor.
Skid control ECUTester Display
| Measurement Item/Range
| Normal Condition
| Diagnostic Notes
|
FR Wheel Speed
| Front speed sensor RH reading/ Min.: 0 km/h (0 mph), Max.: 326.4 km/h (202.8 mph)
| Actual wheel speed
| Similar to speed indicated on speedometer
|
FL Wheel Speed
| Front speed sensor LH reading/ Min.: 0 km/h (0 mph), Max.: 326.4 km/h (202.8 mph)
| Actual wheel speed
| Similar to speed indicated on speedometer
|
- OK:
- There is almost no difference between actual wheel speed and displayed speed value.
- HINT:
- There is a tolerance of +/-10% in the speedometer indication.
3.PERFORM TEST MODE INSPECTION (SIGNAL CHECK) |
Perform a test mode inspection and check for DTCs (RAV4_ACA30 RM000000ONN02FX.html).
- OK:
- No DTC output.
| CHECK AND REPAIR HARNESS OR CONNECTOR (SPEED SENSOR CIRCUIT) |
|
|
Clear the DTC(s) (RAV4_ACA30 RM000000ONJ02UX.html).
Start the engine.
Drive the vehicle at a speed of 20 km/h (12 mph) or more for at least 60 seconds.
Check if the same DTC(s) is output (RAV4_ACA30 RM000000ONJ02UX.html).

5.INSPECT FRONT SPEED SENSOR (INSTALLATION) |
Check that the speed sensor installation bolt is tightened properly.
- OK:
- The installation bolt is tightened properly, and there is no clearance between the sensor and front steering knuckle.
- Torque:
- 8.5 N*m (87 kgf*cm, 75 in.*lbf)
- HINT:
- If the installation portion of the sensor is dirty, clean it and reinstall the sensor.
