CHECK AT THE ECU TERMINALS

M1133004500901

TERMINAL VOLTAGE CHECK CHART

WARNING

A high-tension voltage is flowing between
the engine-ECU and the injectors while the
engine is running. Handle them carefully to
avoid receiving electric shocks from the volt-
age.

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 chart procedures do not have the particu-

lar order.

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.
