DTC C1413 Front Speed Sensor RH Output Malfunction

DTC C1414 Front Speed Sensor LH Output Malfunction


DESCRIPTION

The speed sensor detects wheel speed and sends the appropriate signals to the skid control ECU. These signals are used for ABS/VSC/TRC control.
Speed sensor rotors have rows of alternating N and S magnetic poles, and their magnetic fields change when the rotors turn.
Each speed sensor detects that magnetic change and sends a pulse signal to the skid control ECU.

WIRING DIAGRAM

Refer to DTCs C1401 and C1402 (RAV4_ACA30 RM000000XI905EX_02.html).

INSPECTION PROCEDURE

NOTICE:
When replacing the brake actuator assembly, perform zero point calibration (RAV4_ACA30 RM000001K1O00SX.html).
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 the DTC (RAV4_ACA30 RM000000XHS04QX.html).

    ABS/VSC/TRC:
    Tester Display
    		Measurement Item/Range
    		Normal Condition
    		Diagnostic Note
    FR Speed Open
    		FR speed sensor open detection / ERROR or NORMAL
    		ERROR: Momentary interruption
    NORMAL: Normal
    		-
    FL Speed Open
    		FL speed sensor open detection / ERROR or NORMAL
    		ERROR: Momentary interruption
    NORMAL: Normal
    		-
    OK:
    There are no momentary interruptions.
    HINT:
    Perform the above inspection before removing the sensor and connector.

2.READ VALUE USING INTELLIGENT TESTER (FR/FL WHEEL SPEED)

  1. Turn the ignition switch off.

  1. Connect the intelligent tester to the DLC3.

  1. Start the engine.

  1. Select the Data List mode on the intelligent tester (RAV4_ACA30 RM000000ONK01EX.html).

    ABS/VSC/TRC:
    Tester Display
    		Measurement Item/Range
    		Normal Condition
    		Diagnostic Note
    FR Wheel Speed
    		FR wheel speed sensor reading / min.: 0 km/h (0 mph), max.: 326.4 km/h (202.8 mph)
    		Actual wheel speed
    		Similar to speed indicated on the speedometer.
    FL Wheel Speed
    		FL wheel speed sensor reading /min.: 0 km/h (0 mph), max.: 326.4 km/h (202.8 mph)
    		Actual wheel speed
    		Similar to speed indicated on the speedometer.

  1. Check that there is no difference between the speed value output from the speed sensor displayed on the intelligent tester and the speed value displayed on the speedometer when driving the vehicle.

    HINT:
    Factors that affect the indicated vehicle speed include tire size, tire inflation, and tire wear. The speed indicated on the speedometer has an allowable margin of error. This can be tested using a speedometer tester (calibrated chassis dynamometer). For details about testing and the margin of error, see the reference chart (RAV4_ACA30 RM0000020M9001X.html).
    OK:
    The speed value output from the speed sensor displayed on the intelligent tester is the same as the actual vehicle speed measured using a speedometer tester (calibrated chassis dynamometer).

3.RECONFIRM DTC

  1. Turn the ignition switch off.

  1. Clear the DTCs (RAV4_ACA30 RM000000ONJ027X.html).

  1. Start the engine.

  1. Drive the vehicle at a speed of 40 km/h (25 mph) or more for at least 60 seconds.

  1. Check if the same DTC is output (RAV4_ACA30 RM000000ONJ027X.html).

    Result:
