Confirmation Procedure
Before performing the following procedures, confirm that battery voltage is higher than 12 V.
Turn ignition switch off.
Connect X-431 3G diagnostic tester (the latest version) to Data Link Connector (DLC).
Turn ignition switch ON.
Using diagnostic tester, select Read Datastream.
If the datastream is not detected, the malfunction indicated by the datastream is current. Go to the
diagnosis procedure - Step 1.
If the datastream is detected, the malfunction indicated by the datastream is intermittent (
Diagnosis Procedure
a. Turn ignition switch off.
b. Disconnect ECM connector E-033.
c. Check voltage between terminals of ECM connector
E-033 and body ground.
a. Unplug ECM fuse EF19 (10A) from engine compartment fuse and relay box.
b. Check resistance of fuse.
Standard resistance: less than 1 Ω
