Specification data are reference values and are measured between each terminal and ground.
Pulse signal is measured by CONSULT-III.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.

Diagnosis Procedure
INFOID:0000000001327070
1.
CHECK ENGINE START
Turn ignition switch OFF, and restart engine.
Is engine running?
Yes or No
Yes (With CONSULT-III)>>GO TO 2.
Yes (Without CONSULT-III)>>GO TO 3.
No
>> GO TO 4.
2.
CHECK OVERALL FUNCTION
With CONSULT-III
1.
Perform “POWER BALANCE” in “ACTIVE TEST” mode with CONSULT-III.
2.
Make sure that each circuit produces a momentary engine speed drop.
OK or NG
OK
>> INSPECTION END
NG
>> GO TO 10.
3.
CHECK OVERALL FUNCTION
Without CONSULT-III
1.
Let engine idle.
2.
Read the voltage signal between ECM terminals 46, 60, 61, 62,
65, 79, 80, 81 and ground with an oscilloscope.
3.
Verify that the oscilloscope screen shows the signal wave as
shown below.
NOTE:
The pulse cycle changes depending on rpm at idle.
