1. Use the Active Test to check the operation of the speedometer (Refer to DATA LIST / ACTIVE TEST [10/2015 - ] ).
   COMBINATION METER
   
   

   Tester Display	Test Part	Control Range	Diagnostic Note
   Speed Meter Operation	Speedometer	0, 40, 80, 120, 160 (mph) *1	Acceptable range (mph): [Control range → Speedometer display] except Sport Package  40 → 39 to 41.8 80 → 79.2 to 82.4 120 → 119.6 to 122.8 for Sport Package  40 → 39.6 to 42.4 80 → 80.5 to 83.7 120 → 121.5 to 124.7 160 → 162.6 to 165.8
   		0, 40, 80, 120, 160, 200 or 240 (km/h)*2	Acceptable range (km/h): [Control range → Speedometer display] except Sport Package  40 → 38.2 to 42.7 80 → 78.3 to 83.3 120 → 118.7 to 123.7 160 → 159.1 to 164.1 200 → 199.5 to 204.5 240 → 239.9 to 244.9 except Sport Package  40 → 38.8 to 43.3 80 → 79.6 to 84.6 120 → 120.6 to 125.6 160 → 161.7 to 166.7 200 → 202.7 to 204.5 240 → 243.7 to 248.7

   • *1: for U.S.A.
   • *2: for Canada

   OK

   Speedometer indication is normal.

Result:  NG

NG 

REPLACE COMBINATION METER ASSEMBLY 

(Refer to REMOVAL [09/2014 - ] )

Result:  OK

OK 

See step  3

1. Use the Data List to check if the speedometer is operating properly (Refer to DATA LIST / ACTIVE TEST [10/2015 - ] ).
   COMBINATION METER
   
   

   Tester Display	Measurement Item/Range	Normal Condition	Diagnostic Note
   Vehicle Speed Meter	Vehicle speed / Min.: 0 mph (0 km/ h), Max.: 255 km/h (158 mph)	Almost same as actual vehicle speed	-

   OK

   Vehicle speed displayed on the Techstream is almost the same as the actual vehicle speed measured using a speedometer tester (calibrated chassis dynamometer).

Result:  NG

NG 

REPLACE COMBINATION METER ASSEMBLY 

(Refer to REMOVAL [09/2014 - ] )

Result:  OK

OK 

See step  4

1. Use the Data List to check the wheel speed (Refer to DATA LIST / ACTIVE TEST [10/2015 - ] ).
   ABS/VSC/TRAC
   
   

   Tester Display	Measurement Item/Range	Normal Condition	Diagnostic Note
   FR Wheel Speed	Vehicle speed / Min.: 0 mph (0 km/ h), Max.: 326 km/h (202 mph)	Almost same as actual vehicle speed measured using speedometer tester	-
   FL Wheel Speed	Vehicle speed / Min.: 0 mph (0 km/ h), Max.: 326 km/h (202 mph)		-
   RR Wheel Speed	Vehicle speed / Min.: 0 mph (0 km/ h), Max.: 326 km/h (202 mph)		-
   RL Wheel Speed	Vehicle speed / Min.: 0 mph (0 km/ h), Max.: 326 km/h (202 mph)		-

   OK

   Vehicle speed displayed on the Techstream is almost the same as the actual vehicle speed measured using a speedometer tester (calibrated chassis dynamometer).

Result:  NG

NG 

GO TO ELECTRONICALLY CONTROLLED BRAKE SYSTEM 

(Refer to HOW TO PROCEED WITH TROUBLESHOOTING [09/2014 - ] )

Result:  OK

OK 

See step  5

1. Replace the combination meter assembly with a new or normally functioning one (Refer to REMOVAL [09/2014 - ] ).

   OK

   The operation of the speedometer returns to normal.

Result:  OK

OK 

END (COMBINATION METER ASSEMBLY WAS DEFECTIVE) 

Result:  NG
