When the cable is disconnected and reconnected to the negative (-) battery terminal, the power source mode returns to the state it was in before the cable was disconnected.
PROCEDURE
1. | READ VALUE USING TECHSTREAM (VEHICLE SPEED METER) |
(a) Connect the Techstream to the DLC3.
(b) Turn the engine switch on (IG).
(c) Turn the Techstream on.
(d) Enter the following menus: Body Electrical / Combination Meter / Data List.
(e) Read the Data List according to the display on the Techstream.
Body Electrical > Combination Meter > Data List Tester Display | Measurement Item | Range | Normal Condition | Diagnostic Note |
---|---|---|---|---|
Vehicle Speed Meter | Vehicle speed | Min.: 0, Max.: 255 | Almost same as actual vehicle speed (Speedometer tester) | - |
Tester Display |

Vehicle Speed Meter |
HINT:
Using a speedometer tester, check the actual vehicle speed and the vehicle speed displayed on the Techstream.
OK:
Vehicle speed displayed on the Techstream is almost the same as the actual vehicle speed measured using a speedometer tester.
