4. READ VALUE USING TECHSTREAM (REAR SPEED SENSOR)
(a) Turn the ignition switch off.
(b) Connect the Techstream to the DLC3.
(c) Start the engine.
(d) Select Data List mode on the Techstream See: Brakes and Traction Control/Antilock Brakes / Traction Control Systems/Testing and
Inspection/Scan Tool Testing and Procedures/ABS (Antilock Brake System)/Data List / Active Test.
ABS/VSC/TRAC
ABS/VSC/TRAC
(e) Check that there is no difference between the speed value output from the speed sensor displayed on the Techstream 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 See: Instrument Panel, Gauges and Warning
Indicators/Testing and Inspection/Component Tests and General Diagnostics/On-Vehicle inspection.
OK:
The speed value output from the speed sensor displayed on the Techstream is the same as the actual vehicle speed measured
using a speedometer tester (calibrated chassis dynamometer).
NG -- CHECK REAR SPEED SENSOR INSTALLATION
OK -- Continue to next step.
5. PERFORM TEST MODE (SIGNAL CHECK)
(a) Turn the ignition switch off.
(b) Perform the sensor check in the Test Mode procedure See: Brakes and Traction Control/Antilock Brakes / Traction Control
Systems/Testing and Inspection/Scan Tool Testing and Procedures/ABS (Antilock Brake System)/Test Mode Procedure.
OK:
All Test Mode DTCs are cleared.
NG -- CHECK REAR SPEED SENSOR INSTALLATION
OK -- Continue to next step.
6. RECONFIRM DTC
(a) Turn the ignition switch off.
(b) Clear the DTCs See: Brakes and Traction Control/Antilock Brakes / Traction Control Systems/Testing and Inspection/Reading and
Clearing Diagnostic Trouble Codes/ABS (Antilock Brake System).
(c) Start the engine.
(d) Drive the vehicle at a speed of 40 km/h (25 mph) or more for at least 60 seconds.
(e) Check if the same DTC is recorded See: Brakes and Traction Control/Antilock Brakes / Traction Control Systems/Testing and
Inspection/Reading and Clearing Diagnostic Trouble Codes/ABS (Antilock Brake System).
