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

Speed sensor check (when using sst check wire)
(a) Check the speed sensor signal.
(1) Drive the vehicle straight forward. Drive the
vehicle at a speed of 45 km/h (28 mph) or higher
for several seconds and check that the ABS
warning light goes off.
HINT:
The signal check may not be completed if the
vehicle has its wheels spun or the stee ...
Replacement
1. REPLACE GENERATOR DRIVE END FRAME BEARING
(a) Remove the 4 screws and retainer plate from the
drive end frame.
(b) Using SST and a hammer, tap out the drive end
frame bearing from the drive end frame.
