CAUTION

When shifting the select lever to D range, the brakes should be applied so that the vehicle does not 
move forward

NOTE: *1: On the new vehicle (mileage: 500 km or less), air flow sensor output frequency may be higher by 
approx. 10%.

NOTE: *2: Injector drive time ranges shown are when power voltage is 11 V and the cranking speed is 250 
r/min. or less.

NOTE: *3: On the new vehicle (mileage: 500 km or less), injector drive time may be longer by approx. 10%.

NOTE: *4: On the new vehicle (mileage: 500 km or less), the number of steps of stepper motor may be larger 
by approx. 30 steps.

NOTE: *5: When service data in check mode is selected, the data is not displayed.

CHECK AT THE ECU TERMINALS

M1131153500175

TERMINAL VOLTAGE CHECK CHART

1. Connect a needle-nosed wire probe to a voltmeter 

probe.

2. Insert the needle-nosed wire probe into each of 

the engine-ECU connector terminals from the wire 
side, and measure the voltage while referring to 
the check chart.

NOTE: 

.

1. Make the voltage measurement with the 

engine-ECU connector connected.

2. You may find it convenient to pull out the 

engine-ECU to make it easier to reach the 
connector terminals.

3. The checks can be carried out off the order 

given in the chart.

CAUTION

Short-circuiting the positive (+) probe between a 
connector terminal and earth could damage the 
vehicle wiring, the sensor, engine-ECU or all of 
them. Be careful to prevent this!
3. If voltmeter shows any division from standard 

value, check the corresponding sensor, actuator 
and related electrical wiring, then repair or 
replace.

4. After repair or replacement, recheck with the 

voltmeter to confirm that the repair has corrected 
the problem.
