5. Does back door auto closure system operate normally? If Yes, GO TO 6, If No, GO TO 4.
6. INSPECTION END
Preliminary CheckNIS001OR
Remove the fuse No.18 for the back door closure with the back door closure inactive.
Check that the back door can be open / close normally.
CAUTION:
It is judged it is abnormal, discontinues closure operation, and drive lever returns to a neutral position
if not becoming full-latch within about three seconds after half-latch.
When this operation is done continuously three times, both back door closure and back door opener
switch are not operated because the function of back door closure is stopped.
Thing to reset power supply by pulling out and opening fuse in that case.

ABS
The Anti-Lock Braking System is a function that detects wheel revolution while braking, and it improves
handling stability during sudden braking by electrically preventing 4 wheel lock. Maneuverability is also
improved for avoiding obstacles.
If the electrical system malfunctions, then the fail-safe function starts, the ABS becomes inoperative, and
ABS warning lamp turns on.
Electrical system diagnosis by CONSULT-II is available.
During ABS operation, brake pedal lightly vibrates and a mechanical noise may be heard. This is normal.
When starting engine, or just after starting vehicle, brake pedal may vibrate or motor operating noises
may be heard from engine compartment. This is a normal status of operation check.
Stopping distance may be longer than that of vehicles without ABS when vehicle drives on rough, gravel,
or snow-covered (fresh, deep snow) roads.
EBD
The Electronic Brake Distribution is a function that detects subtle slippages between front and rear wheels
during braking, and it improves handling stability by electronically controlling the brake fluid pressure
which results in reduced rear wheel slippage.
In case of electrical system malfunction, the fail-safe function is activated, EBD and ABS becomes inoper-
ative, and ABS warning lamp and brake warning lamp are turned on.
Electrical system diagnosis by CONSULT-II is available.
During EBD operation, brake pedal lightly vibrates and a mechanical noise may be heard. This is normal.
When starting engine, or just after starting vehicle, brake pedal may vibrate or motor operating noises
may be heard from engine compartment. This is a normal status of operation check.
Stopping distance may be longer than that of vehicles without EBD when vehicle drives on rough, gravel,
or snow-covered (fresh, deep snow) roads.
Fail-Safe FunctionNFS000N8
VDC / TCS SYSTEM
In case of malfunction in the VDC/TCS system, VDC OFF indicator lamp and SLIP indicator lamp are turned
on, and the condition of vehicle is the same as the condition of vehicles without VDC/TCS system. In case of
malfunction in the VDC/TCS system, the ABS control continues to operate normally without VDC/TCS control.
CAUTION:
If the fail-safe function is activated, then perform the self-diagnosis for VDC/TCS/ABS control system.
ABS, EBD SYSTEM
In case of electrical malfunctions with the ABS, ABS warning lamp, VDC OFF indicator lamp and SLIP indica-
tor lamp will turn on. In case of electrical malfunctions with the EBD, brake warning lamp, ABS warning lamp,
VDC OFF indicator lamp and SLIP indicator lamp will turn on. Simultaneously, the VDC/TCS/ABS become one
of the following conditions of the fail-safe function.
For malfunction of ABS, only the EBD is activated and the condition of vehicle is the same condition of
vehicles without TCS/ABS system.
NOTE:
ABS self-diagnosis sound may be heard. That is a normal condition because a self-diagnosis for “Ignition
switch ON” and “The first starting” are being performed.
For malfunction of EBD, EBD and ABS become inoperative, and the condition of vehicle is the same as
the condition of vehicles without TCS/ABS, EBD system.
