Specification data are reference values and are measured between each terminal and ground.
Pulse signal measured by CONSULT-II.
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.

Diagnostic Procedure
EBS00MNY
1.
CHECK ENGINE START
Turn ignition switch “OFF”, and restart engine.
Is engine running?
Yes or No
Yes (With CONSULT-II)>>GO TO 2.
Yes (Without CONSULT-II)>>GO TO 3.
No
>> GO TO 4.
2.
CHECK OVERALL FUNCTION
With CONSULT-II
1.
Perform “POWER BALANCE” in “ACTIVE TEST” mode with
CONSULT-II.
2.
Make sure that each circuit produces a momentary engine
speed drop.
OK or NG
OK
>> INSPECTION END
NG
>> GO TO 11.

IGNITION SIGNAL
3.
CHECK OVERALL FUNCTION
Without CONSULT-II
1.
Let engine idle.
2.
Read the voltage signal between ECM terminals 18, 19, 20, 21,
29, 30, 31, 32 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.
OK or NG
OK
>> INSPECTION END
NG
>> GO TO 11.
4.
CHECK IGNITION COIL POWER SUPPLY CIRCUIT-I
1.
Turn ignition switch ON.
2.
Check voltage between ECM terminals 163, 166 and ground
with CONSULT-II or tester.
OK or NG
OK
>> GO TO 5.
NG
>> Go to
EC-133, "POWER SUPPLY CIRCUIT FOR ECM"
.
5.
CHECK IGNITION COIL POWER SUPPLY CIRCUIT-II
Check voltage between ECM terminal 12 and ground with CON-
SULT-II or tester.
OK or NG
OK
>> GO TO 11.
NG
>> GO TO 6.
