Speedometer Malfunction [08/2015 - 08/2019]: Procedure

1. Check if a CAN communication DTC is output (Refer to DIAGNOSIS SYSTEM [08/2015 - 08/2019] ).
   RESULT
   
   

   Result	Proceed to
   CAN communication DTC is not output	A
   CAN communication DTC is output	B

Result: 

B 

GO TO CAN COMMUNICATION SYSTEM 

(Refer to HOW TO PROCEED WITH TROUBLESHOOTING [08/2015 - 08/2019] )

Result: 

A 

See step  2

1. Use the Active Test to check the operation of the speedometer (Refer to DATA LIST / ACTIVE TEST [08/2015 - 08/2017] , or refer to DATA LIST / ACTIVE TEST [08/2017 - 08/2019] ).
   COMBINATION METER
   
   

   Tester Display	Test Part	Control Range	Diagnostic Note
   Speed Meter Operation	Speedometer	0, 40, 80, 120 mph*1	Acceptable range (mph): [Control range → Speedometer display] 40 → 39 to 42.5 80 → 79 to 84 120 → 119 to 125.5 Confirm that the vehicle is stopped with the engine idling.
   		0, 40, 80, 120, 160 km/h*2	Acceptable range (km/h): [Control range → Speedometer display] 40 → 38 to 43.5 80 → 78 to 85 120 → 118.5 to 126.5 160 → 158.5 to 168 Confirm that the vehicle is stopped with the engine idling.

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

   OK

   Speedometer indication is normal.

Result: 

NG 

REPLACE COMBINATION METER ASSEMBLY 

(Refer to REMOVAL [08/2015 - 08/2019] )

Result: 

OK 

See step  3

1. Use the Data List to check if the speedometer is operating properly (Refer to DATA LIST / ACTIVE TEST [08/2015 - 08/2017] , or refer to DATA LIST / ACTIVE TEST [08/2017 - 08/2019] ).
   COMBINATION METER
   
   

   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 measured using a speedometer tester	-

   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: 

OK 

REPLACE COMBINATION METER ASSEMBLY 

(Refer to REMOVAL [08/2015 - 08/2019] )

Result: 

NG 

See step  4

1. Use the Data List to check the wheel speed (Refer to DATA LIST / ACTIVE TEST [08/2015 - 08/2019] ).
   ABS/VSC/TRAC
   
   

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

   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 

GO TO VEHICLE STABILITY CONTROL SYSTEM 

(Refer to HOW TO PROCEED WITH TROUBLESHOOTING [08/2015 - ] )

Result: 

OK 

See step  5

1. Replace the skid control ECU with a new or normally functioning one (Refer to DISASSEMBLY [08/2015 - ] ).

   OK

   The operation of the speedometer returns to normal.

Result: 

OK 

END 

Result: 

NG 

REPLACE COMBINATION METER ASSEMBLY
