ON-VEHICLE SERVICE

CHECK THE SPEEDOMETER

M1540201400608

CAUTION

Since the diagnosis code may be stored in the
ABS-ECU or ASTC-ECU when checking the
speedometer with speedometer tester, erase the
diagnosis code.

CAUTION

Do not accelerate or decelerate suddenly during
servicing work.
1. Check that the current tyre inflation pressures

meet the inflation pressure label (Refer to
GROUP 31

− On-vehicle Service ).

2. Move <4WD> transfer shift lever to "4H" position.

3. Set the vehicle on the speedometer tester and set

the front wheels on the free roller.

4. For prevention of front wheel lateral runout, install

chain or wire (the other end of which is tightly
fixed on front towing hooks) on the vehicle.

5. For prevention of rear wheel lateral runout and of

vehicle from starting out, install extension fittings
on rear towing hooks, and install both ends in the
anchor plate.

6. Check that the speedometer indicating range is

within the standard value and the needle
fluctuation is within the limit.

TACHOMETER CHECK

M1540201500036

1. Connect the engine speedometer to the fuel

injection pipe.

2. Compare the readings of the engine speedometer

and the tachometer at every engine speed, and
check if the variation are within the standard
value.

Standard value:

NOTE: The value in parentheses is a reference
value.

FUEL GAUGE UNIT CHECK

M1540201600657

NOMINAL RESISTANCE OF THE FUEL GAUGE
UNIT
1. Remove the fuel gauge unit (Refer to GROUP

13B, Fuel Tank ).

2. When float of the fuel gauge unit is in stopper

positions "F" and "E", ensure that resistance
between the fuel gauge unit terminal and earth
terminal is within the standard value.

Standard value:

3. When the float is moved slowly between stopper

positions "F" and "E", ensure that the resistance is
smoothly changing.

FUEL GAUGE UNIT FLOAT HEIGHT
1. Remove the fuel gauge unit (Refer to GROUP

13B, Fuel Tank ).
