Speedometer Malfunction [09/2014 - 10/2015]: Procedure
- CHECK CAN COMMUNICATION SYSTEM
- Check if a CAN communication DTC is output (Refer to DIAGNOSIS SYSTEM [09/2014 - 10/2015]
).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 [09/2014 - 10/2015] )
Result:
A
See step 2
- Check if a CAN communication DTC is output (Refer to DIAGNOSIS SYSTEM [09/2014 - 10/2015]
).
- PERFORM ACTIVE TEST USING TECHSTREAM (SPEED METER OPERATION)
- Use the Active Test to check the operation of the speedometer (Refer to DATA LIST / ACTIVE TEST [09/2014 - 10/2015]
).COMBINATION METER
Tester Display Test Part Control Range Diagnostic Note Speed Meter Operation Speedometer 0, 40, 80, 120, 160, 200, 240 (mph)*1 Acceptable range (mph): [Control range → Speedometer display] - 40 → 39.2 to 42.4
- 80 → 79.8 to 83.4
- 120 → 120.6 to 124.4
- 160 → 161.3 to 165.3
Confirm that the vehicle is stopped with the engine idling.0, 40, 80, 120, 160, 200, 240 (km/h)*2 Acceptable range (km/h): [Control range → Speedometer display] - 40 → 38.6 to 43.1
- 80 → 78.8 to 84.3
- 120 → 119.5 to 125.5
- 160 → 160.1 to 166.6
- 200 → 200.6 to 207.6
- 240 → 241.4 to 248.4
Confirm that the vehicle is stopped with the engine idling.- *1: for U.S.A.
- *2: for Canada
OK
Speedometer indication is normal.
Result:
NG
REPLACE COMBINATION METER ASSEMBLY
(Refer to REMOVAL [09/2014 - ] )
Result:
OK
See step 3
- Use the Active Test to check the operation of the speedometer (Refer to DATA LIST / ACTIVE TEST [09/2014 - 10/2015]
).
- READ VALUE USING TECHSTREAM (VEHICLE SPEED METER)
- Use the Data List to check if the speedometer is operating properly (Refer to DATA LIST / ACTIVE TEST [09/2014 - 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
REPLACE COMBINATION METER ASSEMBLY
(Refer to REMOVAL [09/2014 - ] )
Result:
OK
See step 4
- Use the Data List to check if the speedometer is operating properly (Refer to DATA LIST / ACTIVE TEST [09/2014 - 10/2015]
).
- READ VALUE USING TECHSTREAM (FR/FL/RR/RL WHEEL SPEED)
- Use the Data List to check the wheel speed (Refer to DATA LIST / ACTIVE TEST [09/2014 - 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
GO TO VEHICLE STABILITY CONTROL SYSTEM
(Refer to HOW TO PROCEED WITH TROUBLESHOOTING [09/2014 - 10/2015] )
Result:
OK
See step 5
- Use the Data List to check the wheel speed (Refer to DATA LIST / ACTIVE TEST [09/2014 - 10/2015]
).
- CHECK COMBINATION METER ASSEMBLY
- 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
END (COMBINATION METER ASSEMBLY WAS DEFECTIVE)
Result:
NG
REPLACE BRAKE ACTUATOR ASSEMBLY
(Refer to REMOVAL [09/2014 - 10/2015] )
- Replace the combination meter assembly with a new or normally functioning one (Refer to REMOVAL [09/2014 - ]
).
