COMBINATION METER TERMINAL CHECK

M1543026700010

Measure the voltage between terminals using a volt-
meter.

NOTE: The combination meter connector is fixed on the instrument panel directly, so you can not take mea-
surement by backprobing.

CAUTION

Never take a measurement at terminals 14 and
15. If you do this, the CAN bus lines will be
impaired.

ON-VEHICLE SERVICE

SPEEDOMETER CHECK

M1543000900445

1. Adjust the pressure of tires to the specified level (Refer to

GROUP 31, On-vehicle Service

P.31-7

).

CAUTION

Do not accelerate or decelerate suddenly during servicing
work.
2. Set the vehicle onto a speedometer tester and use wheel

chocks to hold the rear wheels.

3. To prevent the front wheel from moving from side to side,

attach tension bars to the tie-down hook, and secure both
ends to anchor plates.

4. To prevent the vehicle from moving, attach a chain or wire to

the rear retraction hook, and make sure the end of the chain
or wire is secured.

5. Check if the speedometer indicator range is within the

standard values.

6. If not within the standard value, check the tire size. If an

incorrect size of tire is used, replace it and check again. If
the tire size is correct, a defect may be present in
components and circuit between the output shaft speed
sensor and the combination meter. Check the following
items.

• output shaft speed sensor (refer to GROUP23A, Automatic

Transaxle Diagnosis

P.23A-90

).

• combination meter (refer to

P.54A-83

.)
