ON-VEHICLE SERVICE
CHECK THE SPEEDOMETER.
M1543000900553
CAUTION
Since the diagnosis code may be stored in the
ABS-ECU or the ASC-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 tyre pressure is within the tyre
pressure label. (Refer to GROUP 31 - On-vehicle
Service
2. Set the vehicle on the speedometer tester.
3. Chock the rear wheels and depress the parking
brake pedal.
4. 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.
5. 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.
6. Check that the speedometer indicating range is
within the standard value or the needle fluctuation
is within the limit.
Standard value:
Limit: Needle fluctuation (Driving speed is 35
km/h (21 mph) or more)
± 3 km/h (1 mph)
TACHOMETER CHECK
M1543001000531
Check that the tachometer indicating error is within
the standard value when the actuator tests (item
No.85 and 86) are performed using MUT-III.
Standard value:

FUEL TANK GAUGE UNIT RESISTANCE
FUEL TANK PUMP AND GAUGE UNIT
ASSEMBLY
1. Check that the resistance value between the fuel
tank pump and gauge unit assembly terminal and
the earth terminal is at the standard value when
the float of the fuel tank pump and gauge unit
assembly is at the F position and the E position.
Standard values:
2. Check that the resistance value changes
smoothly when the float is moved slowly between
the F position and the E position.
3. If all checks are correct, go to fuel tank pump and
gauge unit assembly float height check. If any
check is not correct, replace the fuel tank pump
and gauge unit assembly.
FUEL TANK GAUGE UNIT
1. Check that the resistance value between the fuel
