DESCRIPTION
Factors that affect the indicated vehicle speed include tire size, tire inflation, and tire wear. The speed indicated on the speedometer has an allowable margin of error. This can be tested using a speedometer tester (calibrated chassis dynamometer). For details about testing and the margin of error, see the reference chart.

INSPECTION PROCEDURE
NOTICE: If the vehicle speed is outside the allowable range when tested, perform the following procedure.
1 PERFORM ACTIVE TEST BY INTELLIGENT TESTER
METER:
*1: for U.S.A.
*2: Except for U.S.A.
OK: Needle indication is within the allowable range.
2 READ VALUE OF INTELLIGENT TESTER
METER:
OK: Vehicle speed displayed on the tester is almost the same as the actual vehicle speed measured using a speedometer tester (calibrated chassis dynamometer).
REPLACE COMBINATION METER ASSEMBLY
3 READ VALUE OF INTELLIGENT TESTER
ABS/TRAC/VSC:
OK: Vehicle speed displayed on the tester is almost the same as the actual vehicle speed measured using a speedometer tester (calibrated chassis dynamometer).
4 INSPECT COMBINATION METER ASSEMBLY
Standard voltage
*1: without VSC
*2: with VSC
Result
5 INSPECT COMBINATION METER ASSEMBLY
OK: The waveform is displayed as shown in the illustration.
HINT: As the vehicle speed increases, the cycle of the signal waveform narrows.
Result
REPLACE COMBINATION METER ASSEMBLY
6 CHECK HARNESS AND CONNECTOR (COMBINATION METER - BRAKE ACTUATOR ASSEMBLY)
Standard resistance
REPLACE COMBINATION METER ASSEMBLY
7 CHECK HARNESS AND CONNECTOR (COMBINATION METER - ABS & TRACTION ACTUATOR ASSEMBLY)
Standard resistance
REPLACE COMBINATION METER ASSEMBLY
Operating Light Control Rheostat does not Change Light Brightness
DESCRIPTION
The meter CPU receives signals for adjusting illumination on the meter from
this circuit. The meter CPU
detects the illumination level selected by the user according to the position of
the rheostat knob.
