REMOVAL
1. Remove front cover. Refer to EM-38, "REMOVAL" .
2. Remove the oil pump drive spacer.
3. Remove the oil pump.
INSTALLATION
Installation is in the reverse order of removal, paying attention of the following:

When inserting the oil pump drive spacer, align the crankshaft
key and the flat face of the inner rotor.

If they are not aligned, rotate the oil pump inner rotor by hand.

Make sure that the each part is aligned and tap lightly until it
reaches the end.

Fuse EKS00GKH

If fuse is blown, be sure to eliminate cause of incident before
installing new fuse.

Use fuse of specified rating. Never use fuse of more than speci-
fied rating.

Do not partially install fuse; always insert it into fuse holder prop-
erly.

Remove fuse for “ELECTRICAL PARTS (BAT)” if vehicle is not
used for a long period of time.
Fusible Link EKS00GKI
A melted fusible link can be detected either by visual inspection or by feeling with finger tip. If its condition is
questionable, use circuit tester or test lamp.
CAUTION:

If fusible link should melt, it is possible that critical circuit (power supply or large current carrying
circuit) is shorted. In such a case, carefully check and eliminate cause of incident.

Never wrap outside of fusible link with vinyl tape.

Never let fusible link touch any other wiring harness, vinyl or rubber parts.
Circuit Breaker (Built Into BCM)EKS00GKJ
For example, when current is 30A, the circuit is broken within 8 to 20
seconds.
A circuit breaker is used for the following systems:

Power windows

Power door locks

Remote keyless entry system

Power sunroof

Rear window wiper

1. Turn off all loads on the vehicle electrical system. Clean or repair
as necessary.
2. Visually inspect the battery, battery terminals and cable ends with ignition switch in “OFF” position.
NOTE:
The contact surface between the battery terminals, cable ends
and tester leads must be clean for a valid test. A poor connec-
tion will prevent testing and a “CHECK CONNECTION” mes-
sage will appear during the test procedures. If this occurs, clean
the battery post and terminals, reconnect them and restart the
test.
3. Connect the red tester lead clamp to the positive battery termi- nal, and the black to the negative terminal.
4. The tester will turn on automatically. Using the arrow keys, select “IN-VEHICLE” on the tester and then press the “ENTER ”
key.
5. Locate the battery type and rating stamped or written on the top case of the battery to be tested.
NOTE:
The battery rating will be either of the following:

CCA: Cold Cranking Amps (490 CCA, 550 CCA, etc.)

JIS: Japanese Industrial Standard.
When using the Battery Tester use the CCA rating only.

The tester requires the CCA rating for the battery be entered
exactly as it is written or stamped on the battery.

(U.S. market) Refer to the latest "Battery Testing" Technical
Service Bulletin (TSB) for a chart which contains these ratings
listed by vehicle.

You must not use the JIS rating.
6. Using the arrow and “ENTER” keys alternately, select the battery type and rating.
NOTE:
The tester lists five choices; CCA, JIS, IEC, DIN, and EN. Only use CCA.
7. Press “ENTER” to begin the test. Diagnosis results are dis-
played on the tester. Refer to SC-8, "
