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 (

See page 06-18

).

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
