Speedometer Malfunction: Procedure

1. Check if a CAN communication DTC is output. Refer to DIAGNOSIS SYSTEM [06/2012 - ] .
   RESULT
   
   

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

B → See step   6 

A: Go to next step 

1. Use the Active Test to check the operation of the speedometer. Refer to DATA LIST / ACTIVE TEST [06/2012 - ] .
   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 mph • 80 → 79 to 84 mph • 120 → 120 to 119 to 125.5 mph 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 km/h • 80 → 78 to 85 km/h • 120 → 118.5 to 126.5 km/h • 160 → 158.5 to 168 km/h Confirm that the vehicle is stopped with the engine idling.

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

   OK

   Speedometer indication is normal.

OK: Go to next step 

1. Use the Data List to check if the speedometer is operating properly. Refer to DATA LIST / ACTIVE TEST [06/2012 - ] .
   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).

NG → See step   4 

OK → See step   7 

1. Use the Data List to check the wheel speed. Refer to DATA LIST / ACTIVE TEST [06/2012 - ] .
   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).

NG → See step   8 

OK: Go to next step 

1. Replace the skid control ECU with a new or normally functioning one. Refer to DISASSEMBLY [06/2012 - ] .

   OK

   The operation of the speedometer returns to normal.

NG → See step   7 

OK → END
