   Refer to DATA LIST / ACTIVE TEST [10/2014 - 09/2017] , or refer to DATA LIST / ACTIVE TEST [09/2017 - 05/2019]

   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 the 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).
