EC-802
[QR (WITHOUT EURO-OBD)]
IGNITION SIGNAL
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 EBS0113Z
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 12.
