Needle indication is normal.
COMBINATION METER:Tester 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 → 40 to 43.5
- 80 → 80 to 84.5
- 120 → 120 to 125.5
for km/h- 40 → 38 to 42
- 80 → 78 to 84
- 120 → 119 to 125
- 160 → 159 to 167
- 200 → 199 to 209
- 240 → 239 to 251
HINT:
- 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.
NG → See step 6
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 METER:Tester Display Measurement Item/Range Normal Condition Diagnostic Note Vehicle Speed Meter Vehicle speed/Min.: 0 (0), Max.: 255 (158) Almost same as actual 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).
ELECTRIC PARKING BRAKE:Tester Display Measurement Item/Range Normal Condition Diagnostic Note (FL/FR/RL/RR) Wheel Speed Wheel speed sensor (FL/FR/RL/RR) reading /Min.: 0 (0), Max.: 326 (202) Actual wheel speed Similar speed as indicated on speedometer
