IGNITION SIGNALPFP:22448
Component DescriptionEBS00N9F
IGNITION COIL & POWER TRANSISTOR
The ignition signal from the ECM is sent to and amplified by the
power transistor. The power transistor turns on and off the ignition
coil primary circuit. This on-off operation induces the proper high
voltage in the coil secondary circuit.
ECM Terminals and Reference ValueEBS00N9G
Specification data are reference values and are measured between each terminal and ground.
Pulse signal is 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.
: Average voltage for pulse signal (Actual pulse signal can be confirmed by oscilloscope.)

Diagnostic Procedure
EBS00N9I
1. CHECK ENGINE START
Turn ignition switch “OFF”, and restart engine.
Is engine running?
Ye s o r N o
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 all circuits do not produce a momentary engine
speed drop.
OK or NG
OK >>INSPECTION END
NG >> GO TO 12.
3. CHECK OVERALL FUNCTION
Without CONSULT-II
1. Let engine idle.
2. Read the voltage signal between ECM terminals 21, 22, 23, 24
and ground with an oscilloscope.
3. Verify that the oscilloscope screen shows the signal wave as
shown below.
OK or NG
OK >>INSPECTION END
NG >> GO TO 12.
