EKS006UR

NOTE:
To ensure a complete and thorough diagnosis, the battery, starter and generator test segments must be done
as a set from start to finish.

1.

Turn off all loads on the vehicle electrical system.

2.

Perform battery test with Battery/Starting/Charging system
tester. Refer to

SC-6, "Trouble Diagnoses with Battery/Starting/

Charging System Tester"

.

3.

Press “ENTER” to begin the starting system test.

4.

Start the engine.

5.

Diagnosis result is displayed on the tester. Refer to

SC-8,

"DIAGNOSTIC RESULT ITEM CHART"

.

NOTE:

●

If the starter performs normally but the engine does not start,

CHECK POWER SUPPLY FOR STARTER MOTOR “B” TERMINAL

1.

Remove the fuel pump fuse.

2.

Crank or start the engine (where possible) until the fuel pressure is released.

3.

Turn the ignition switch OFF.

4.

Check that the starter motor terminal “B” [E210, (B/Y) for KA24DE models or E203, (B/L) for VG33E and
VG33ER models] connection is clean and tight.

5.

Check voltage between starter motor terminal “B” [E210, (B/Y) for KA24DE models or E203, (B/L) for
VG33E and VG33ER models] and ground using a digital circuit tester.

OK or NG

OK

>> GO TO 2.

NG

2.

CHECK BATTERY CABLE CONNECTION QUALITY (VOLTAGE DROP TEST)

1.

Check voltage between starter motor terminal “B” [E210, (B/Y) for KA24DE models or E203, (B/L) for
VG33E and VG33ER models] and battery positive terminal using a digital circuit tester.

OK or NG
