Diagnostic ProcedureEBS00BDB
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.
