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.)
EFS001BS
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.
