Speedometer Malfunction [09/2013 - ]: Procedure
- CHECK CAN COMMUNICATION SYSTEM
- Check if an CAN communication system DTC is output. Refer to DIAGNOSIS SYSTEM [09/2013 - ]
.RESULT
Result Proceed to CAN communication system DTC is not output A CAN communication system DTC is output B
B → See step 8
A: Go to next step
- Check if an CAN communication system DTC is output. Refer to DIAGNOSIS SYSTEM [09/2013 - ]
.
- CHECK ELECTRONICALLY CONTROLLED BRAKE SYSTEM
- Check if an electronically controlled brake system DTC is output. Refer to DTC CHECK / CLEAR [09/2013 - ]
.RESULT
Result Proceed to Electronically controlled brake system DTC is not output A Electronically controlled brake system DTC is output B
B → See step 9
A: Go to next step
- Check if an electronically controlled brake system DTC is output. Refer to DTC CHECK / CLEAR [09/2013 - ]
.
- PERFORM ACTIVE TEST USING TECHSTREAM (SPEED METER OPERATION)
- Using the Techstream, perform the Active Test. Refer to DATA LIST / ACTIVE TEST [09/2013 - ]
.COMBINATION METER
Tester Display Test Part Control Range Diagnostic Note Speed Meter Operation Speedometer 0, 40, 80, 120 or 160 (mph) - 0, 40, 80, 120 or 160 (km/h) OK
Speedometer indication is normal.
NG → See step 7
OK: Go to next step
- Using the Techstream, perform the Active Test. Refer to DATA LIST / ACTIVE TEST [09/2013 - ]
.
- READ VALUE USING TECHSTREAM (ABS/VSC/TRAC)
- Using the Techstream, read the Data List. Refer to DATA LIST / ACTIVE TEST [09/2013 - ]
.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) - Vehicle 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).
NG → See step 9
OK: Go to next step
- Using the Techstream, read the Data List. Refer to DATA LIST / ACTIVE TEST [09/2013 - ]
.
- CHECK COMBINATION METER ASSEMBLY
- Replace the combination meter assembly with a new or normally functioning one. Refer to REMOVAL [09/2013 - ]
.
OK
The operation of the speedometer returns to normal.
NG → See step 6
OK → END (COMBINATION METER ASSEMBLY WAS DEFECTIVE)
- Replace the combination meter assembly with a new or normally functioning one. Refer to REMOVAL [09/2013 - ]
.
- REPLACE BRAKE BOOSTER WITH MASTER CYLINDER ASSEMBLY (SKID CONTROL ECU). Refer to REMOVAL [09/2013 - ]
- REPLACE COMBINATION METER ASSEMBLY. Refer to REMOVAL [09/2013 - ]
- GO TO CAN COMMUNICATION SYSTEM. Refer to HOW TO PROCEED WITH TROUBLESHOOTING [09/2013 - ]
- GO TO ELECTRONICALLY CONTROLLED BRAKE SYSTEM. Refer to HOW TO PROCEED WITH TROUBLESHOOTING [09/2013 - ]
