INSTALLATION
1. Pass hood lock cable through the opening while keeping the
winding radius 100 mm (3.94 in) or larger.
2. After confirming that the grommet is properly positioned, push
the grommet securely into the hole.
3. Apply sealant to the area on the grommet indicated with the *
mark.
4. Connect cable securely to the lock.
5. After connection, confirm proper adjustment and operation for

Hood Lock Control InspectionEIS000KI
NOTE:
If the hood lock cable is bent or deformed, replace it.
1. Confirm hood lock secondary latch securely engages secondary
striker by releasing it from a height of approximately 200 mm
(7.87 in).
2. Confirm front end of the hood rises by approximately 20 mm
(0.79 in) when pulling the hood opener. Also confirm hood
opener returns to the original position.
3. Confirm hood lock has is properly lubricated. If necessary, apply
"Body Grease" at the point shown in the figure.

3.CHECK CONTINUITY BETWEEN IGNITION SWITCH AND ABS WARNING LAMP.
lDisconnect 4WD/ABS control unit connector.
lCheck continuity between ignition switch and 4WD/ABS control module terminal No. 4. (Open circuit
check)
Is inspection result OK?
YES >> Continuity exists. Connect 4WD/ABS control module connector, check again.
NO >> Continuity does not exist. Check ABS warning lamp path.
4.CHECK FUSE.
lCheck if Fuse No.8 is working normally.
Is the check result OK?
YES >> Repair or replace the harness in between 4WD/ABS control unit and IGN.
NO >> Replace the fuse and replace again.
lIf the figure of the monitor is with in±10% of the set value of E-TS solenoid electric current, 4WD/ABS C/
U is operating normally.Check for electric control coupling ASSY is required.
4WD warning lamp does not illuminate with ignition ON.EFS001BR
1.INSPECTION OF BLOWN 4WD WARNING LAMP BULB
lRemove glove box on the passenger side and disconnect the 4WD/ABS control unit connector.
lConfirm continuity between 4WD/ABS control unit connector terminals No. 3 (IGN) and No. 4 (ABS warn-
ing lamp).
Is inspection result OK?
YES >> GO TO 3. (Continuity exists.)
NO >>
lCheck 4WD warning lamp harness.
lRemove meter control module assembly and check for blown 4WD warning lamp bulb.
2.4WD ACTUATOR RELAY HARNESS INSPECTION
lOpen the hood and check that the 4WD relay is properly installed in the relay box.
lConfirm continuity between 4WD/ABS control unit connector terminals No. 7 (4WD warning lamp) and No.
104 (ground).
lConfirm continuity between 4WD/ABS control unit connector terminals No. 3 (IGN) and No. 18 (4WD
actuator relay).
Is inspection result OK?
YES >> Continuity exists. Connect 4WD/ABS control unit connector, check again.
NO >> Check ABS warning lamp harness.
4WD warning lamp does not go out several seconds after engine is started.
(Drive mode indicator lamp goes out.)

1.USING CONSULT, PERFORM SELF-DIAGNOSIS.
4WD warning lamp does not go out several seconds after the engine is started. (Drive mode indicator lamp
goes out.)
Is inspection result OK?
YES >> No malfunction detected. Perform inspection again.
NO >>
lDetermine the location of the malfunction according to the result of self-diagnosis using CON-
SULT. (Malfunction is present in the 4WD system.)
lCONSULT-II does not display ABS -related trouble codes. Proceed to 2.

TROUBLE DIAGNOSIS
Basic Inspection
EBS00BMK
1.INSPECTION START
1. Check service records for any recent repairs that may indicate a related problem, or a current need for
scheduled maintenance.
2. Open engine hood and check the following:
–Harness connectors for improper connections
–Wiring harness for improper connections, pinches and cut
–Vacuum hoses for splits, kinks and improper connections
–Hoses and ducts for leaks
–Air cleaner clogging
–Gasket
3. Confirm that electrical or mechanical loads are not applied.
–Headlamp switch is OFF.
–Air conditioner switch is OFF.
–Rear window defogger switch is OFF.
–Steering wheel is in the straight-ahead position, etc.
4. Start engine and warm it up until engine coolant temperature
indicator points the middle of gauge.
Ensure engine stays below 1,000 rpm.
5. Run engine at about 2,000 rpm for about 2 minutes under no-
load.
6. Make sure that no DTC is displayed with CONSULT-II or GST.
OK or NG
OK >> GO TO 3.

DTC P0420 THREE WAY CATALYST FUNCTIONPFP:20905
On Board Diagnosis LogicEBS00B6A
The ECM monitors the switching frequency ratio of heated oxygen
sensors 1 and 2.
A three way catalyst (Manifold) with high oxygen storage capacity
will indicate a low switching frequency of heated oxygen sensor 2.
As oxygen storage capacity decreases, the heated oxygen sensor 2
switching frequency will increase.
When the frequency ratio of heated oxygen sensors 1 and 2
approaches a specified limit value, the three way catalyst (Manifold)
malfunction is diagnosed.
DTC Confirmation ProcedureEBS00B6B
NOTE:
If “DTC Confirmation Procedure” has been previously conducted, always turn ignition switch “OFF” and wait at
least 10 seconds before conducting the next test.
WITH CONSULT-II
TESTING CONDITION:
lOpen engine hood before conducting the following procedure.
lDo not hold engine speed for more than the specified minutes below.
1. Turn ignition switch “ON”.
2. Select “DTC & SRT CONFIRMATION” then “SRT WORK SUP-
PORT”modewithCONSULT-II.
3. Start engine.
4. Rev engine up to 2,000 to 3,000 rpm and hold it for 3 consecu-
tive minutes then release the accelerator pedal completely.
If "INCMP" of "CATALYST" changed to "COMPLT", go to step 7
5. Wait 5 seconds at idle.
