.
- PERFORM ACTIVE TEST USING TECHSTREAM (SPEEDOMETER)
- Operate the Techstream according to the display and select "Active Test".
OK
Needle indication is normal.
COMBINATION METERTester Display Test Part Control Range Speed Meter Operation Speedometer 0, 40, 80, 120, 160, 200, 240 or 280
HINT:
Acceptable range (mph or km/h): [Control range → Speedometer display]
for mph
• 40 → 39.4 to 42.2
• 80 → 79.9 to 83.1
• 120 → 120.7 to 123.9
for km/h
• 40 → 38.6 to 43.1
• 80 → 79 to 84
• 120 → 119.8 to 124.8
• 160 → 160.5 to 165.5
• 200 → 201.3 to 206.3
• 240 → 242.1 to 247.1HINT:
- Confirm that the vehicle is stopped and engine is idling. It is normal that door will be locked automatically when performing the speedometer Active Test.
- The displayed value has the same units (km/h, mph) as the main scale of the vehicle's speedometer.
- The needle position should be within the acceptable tolerance.

OK: Go to next step
- Operate the Techstream according to the display and select "Active Test".
- READ VALUE USING TECHSTREAM (VEHICLE SPEED)
- Operate the Techstream according to the display and select "Data List".
OK
Vehicle speed displayed on Techstream is almost the same as actual vehicle speed measured using speedometer tester (calibrated chassis dynamometer).
COMBINATION METERTester Display Measurement Item/Range Normal Condition Diagnostic Note Vehicle Speed Meter Vehicle speed/Min.: 0 (0), Max.: 255 (158) Almost same as actual vehicle speed (When driving) Unit: km/h (mph)
NG → See step 4
OK → See step 9
- Operate the Techstream according to the display and select "Data List".
- READ VALUE USING TECHSTREAM (WHEEL SPEED SENSOR)
- Operate the Techstream according to the display and select "Data List".
OK
Vehicle speed displayed on Techstream is almost the same as actual vehicle speed measured using speedometer tester (calibrated chassis dynamometer).
