On Board Diagnosis LogicEBS00KI3
This self-diagnosis has one or tow trip detection logic.
FAIL-SAFE MODE
ECM enters fail-safe mode when malfunction A is detected.
DTC Confirmation ProcedureEBS00KI4
Perform “PROCEDURE FOR MALFUNCTION A” first. If the 1st trip DTC cannot be confirmed, perform
“PROCEDURE FOR MALFUNCTION B”. If there is no malfunction on “PROCEDURE FOR MALFUNC-
TION B”, perform “PROCEDURE FOR MALFUNCTION C”.
NOTE:
If “DTC Confirmation Procedure” has been previously conducted, always turn ignition switch “OFF” and wait at
least 10 seconds before conducting the next test.
PROCEDURE FOR MALFUNCTION A
With CONSULT-II
1. Turn ignition switch “ON”.
2. Select “DATA MONITOR” mode with CONSULT-II.
3. If 1st trip DTC is detected, go to EC-570, "
Diagnostic Procedure"
.

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 ProcedureEBS00KIA
1.CHECK ECM POWER SUPPLY
1. Turn ignition switch “OFF”.
2. Disconnect ECM harness connector.
3. Check voltage between ECM terminal 121 and ground with
CONSULT-II or tester.
OK or NG
OK >> GO TO 3.
NG >> GO TO 2.
2.DETECT MALFUNCTIONING PART
Check the following.
●Harness connectors E225, F43
●10A fuse
●Harness for open or short between ECM and battery
>> Repair open circuit or short to ground or short to power in harness or connectors.
3.CHECK INTERMITTENT INCIDENT
Refer to EC-485, "
TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT" .
OK or NG
OK >> GO TO 4.
NG >> Repair open circuit or short to ground or short to power in harness or connectors.
