on, battery voltage
should exist and after turning ignition switch of
f,
battery voltage will exist a few seconds, then drop
to approximate 0 V.
Is the check result normal?
Ye s>>Check the starting system.
No
>>Go to the next step.
8.CHECK STARTER RELAY (K4) SUPPLY VOLTAGE
• Turn ignition switch off. Wait for at least 10 sec-
onds.
• Check voltage between the ECM terminal 14
and
ground.
• Battery voltage should exist.
Is the check result normal?
Ye s>>Go to the next step.
No
>>Go to step 10.
9.CHECK ECM POWER SUPPLY CIRCUIT - (3)
• Disconnect ECM harness connector.
• Disconnect ECM power supply circuit connector F in front fuse and relay box harness connector.
• Check harness continuity between ECM terminals 44, 45, 63 and front fuse and relay box terminal F3.
• Continuity should exist.
• Also check harness for a short to ground and short to power.
Is the check result normal?
Ye s>>Go to step 11.
No
>>Repair circuit for an open or short to power in harness or connectors.

• If Without EOBD (1.6L): Disconnect fuse 23 (10A), fuse 24 (5A) front fuse and relay box.
• Check fuses.
Is the check result normal?
Ye s>>Go to the next step.
No
>>Replace fuse 23, fuse 24 or fuse 27.
12.CHECK FRONT FUSE AND RELAY BOX
• Check front fuse and relay box.
Is the check result normal?
Ye s>>Replace the ECM.
NOTE : The Immobilizer control module must be matched to the new ECM (See ECM Removal & Instal-
lation in Section 03 Electronic Engine Controls).
No
>>Replace front fuse and relay box.
