Body Electrical > Combination Meter > Data List
Tester Display Measurement Item Range Normal Condition Diagnostic Note Vehicle Speed Meter Vehicle speed Min.: 0 km/h (0 mph), Max.: 255 km/h (158 mph) Almost same as actual vehicle speed - Body Electrical > Combination Meter > Data List
Tester Display Vehicle Speed Meter HINT:
- When the Data List values of the ECUs match, an internal malfunction of the combination meter assembly is suspected.
- When the Data List values of the ECUs do not match, a signal output error of the brake booster with master cylinder assembly (skid control ECU) or an internal malfunction of the combination meter assembly is suspected.
OK
Vehicle speed displayed on the Techstream is almost the same as the actual vehicle speed measured using a speedometer tester (calibrated chassis dynamometer).
