INSPECTION PROCEDURE

NOTICE:
* When replacing the VSC actuator assembly, perform zero point calibration Component Tests and General Diagnostics.
* Check the speed sensor signal in test mode after cleaning or replacement Scan Tool Testing and Procedures.

PROCEDURE

1. READ VALUE USING TECHSTREAM (RL/RR WHEEL SPEED)

(a) Connect the Techstream to the DLC3.

(b) Turn the ignition switch to ON.

(c) Select the Data List mode on the Techstream.

ABS/VSC/TRAC





(d) Check that the speed value output from the speed sensor displayed on the Techstream and the speed value displayed on the speedometer are almost the same when driving the vehicle.

OK:

The speed value output from the speed sensor displayed on the Techstream is the same as the actual vehicle speed.

HINT
There is a tolerance of +/-10% in the speedometer indication.

NG -- CHECK REAR SPEED SENSOR INSTALLATION
OK -- Continue to next step.

2. PERFORM TEST MODE INSPECTION (SIGNAL CHECK)

(a) Perform a TEST MODE inspection and check for DTCs Scan Tool Testing and Procedures.

OK:

No DTCs output.

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR (SPEED SENSOR CIRCUIT)
OK -- Continue to next step.

3. RECONFIRM DTC

(a) Clear the DTC(s) Reading and Clearing Diagnostic Trouble Codes.

(b) Start the engine.

(c) Drive the vehicle at a speed of 20 km/h (12 mph) or more for at least 60 seconds.

(d) Check if the same DTC(s) is output Reading and Clearing Diagnostic Trouble Codes.

B -- REPLACE REAR SPEED SENSOR

A -- USE SIMULATION METHOD TO CHECK How To Proceed With Troubleshooting

4. CHECK REAR SPEED SENSOR INSTALLATION

(a) Check that the speed sensor installation bolt is tightened properly.





OK:

The installation bolt is tightened properly.

NG -- TIGHTEN BOLT PROPERLY
OK -- Continue to next step.

5. CHECK REAR SPEED SENSOR

(a) Visually check the speed sensor for deformation and damage.

OK:

No deformation or damage.

There is no gap between the sensor and rear axle carrier.

NG -- REPLACE REAR SPEED SENSOR
OK -- Continue to next step.

6. CHECK SPEED SENSOR TIP

(a) Remove the speed sensor Removal.

(b) Check the sensor tip.

OK:

No scratches or foreign matter on the sensor tip.

NG -- CLEAN OR REPLACE SPEED SENSOR
OK -- Continue to next step.

7. CHECK HARNESS AND CONNECTOR (SKID CONTROL ECU - REAR SPEED SENSOR)

(a) Confirm that the skid control ECU connector and speed sensor connector are properly connected.





(b) Disconnect the A17 ECU connector.

(c) Disconnect the b3 and b4 sensor connectors.

(d) Inspect both the connector case and the terminal for deformation and corrosion.

OK:

No deformation or corrosion.

(e) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

for RH






for LH:





NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR (SPEED SENSOR CIRCUIT)
OK -- Continue to next step.

8. CHECK REAR SPEED SENSOR (INPUT VOLTAGE)

(a) Reconnect the A17 ECU connector.





(b) Disconnect the b3 and b4 sensor connectors.

(c) Turn the ignition switch to ON.

(d) Measure the voltage according to the value(s) in the table below.

Standard Voltage:





NG -- REPLACE VSC ACTUATOR ASSEMBLY Removal
OK -- Continue to next step.

9. RECONFIRM DTC

(a) Clear the DTC(s) Reading and Clearing Diagnostic Trouble Codes.

(b) Start the engine.

(c) Drive the vehicle at a speed of 20 km/h (12 mph) or more for at least 60 seconds.

(d) Check if the same DTC(s) is output Reading and Clearing Diagnostic Trouble Codes.

Result





B -- USE SIMULATION METHOD TO CHECK How To Proceed With Troubleshooting
A -- Continue to next step.

10. REPLACE REAR SPEED SENSOR

(a) Replace the rear speed sensor Removal.

NEXT -- Continue to next step.

11. RECONFIRM DTC

(a) Clear the DTC(s) Reading and Clearing Diagnostic Trouble Codes.

(b) Start the engine.

(c) Drive the vehicle at a speed of 20 km/h (12 mph) or more for at least 60 seconds.

(d) Check if the same DTC(s) is output Reading and Clearing Diagnostic Trouble Codes.
