+When connecting or disconnecting pin connectors into or
from TCM, take care not to damage pin terminals (bend or
break).
Make sure that there are not any bends or breaks on TCM
pin terminal, when connecting pin connectors.

+Before replacing TCM, perform TCM input/output signal
inspection and make sure whether TCM functions prop-
erly or not. (See page AT-118.)

+After performing each TROUBLE DIAGNOSIS, perform
ªDTC (Diagnostic Trouble Code) CONFIRMATION PROCE-
DUREº.
The DTC should not be displayed in the ªDTC CONFIRMA-
TION PROCEDUREº if the repair is completed.
+Before proceeding with disassembly, thoroughly clean the out-
side of the transaxle. It is important to prevent the internal parts
from becoming contaminated by dirt or other foreign matter.
+Disassembly should be done in a clean work area.
+Use lint-free cloth or towels for wiping parts clean. Common
shop rags can leave fibers that could interfere with the opera-
tion of the transaxle.
+Place disassembled parts in order for easier and proper
assembly.
+All parts should be carefully cleaned with a general purpose,
non-flammable solvent before inspection or reassembly.
+Gaskets, seals and O-rings should be replaced any time the
transaxle is disassembled.
+It is very important to perform functional tests whenever they
are indicated.
+The valve body contains precision parts and requires extreme
care when parts are removed and serviced. Place disas-
sembled valve body parts in order for easier and proper
assembly. Care will also prevent springs and small parts from
becoming scattered or lost.
+Properly installed valves, sleeves, plugs, etc. will slide along
bores in valve body under their own weight.
+Before assembly, apply a coat of recommended ATF to all

2. Remove brake caliper assembly and rotor.
Brake hose need not be disconnected from brake caliper. In
this case, suspend caliper assembly with wire so as not to
stretch brake hose. Be careful not to depress brake pedal, or
piston will pop out.
Make sure brake hose is not twisted.

Checking Body CorrosionNJBT0033Visually check the body sheet metal panel for corrosion, paint damage (scratches, chipping, rubbing, etc.) or
damage to the anti-corrosion materials. In particular, check the following locations.
Hemmed portion
Hood front end, door lower end, trunk lid rear end, etc.
Panel joint
Side sill of rear fender and center pillar, rear wheel housing of rear fender, around strut tower in engine
compartment, etc.
Panel edge
Trunk lid opening, sunroof opening, fender wheelarch flange, fuel filler lid flange, around holes in panel, etc.
Parts contact
Waist molding, windshield molding, bumper, etc.
Protectors
Damage or condition of mudguard, fender protector, chipping protector, etc.
Anti-corrosion materials
Damage or separation of anti-corrosion materials under the body.
Drain holes
Condition of drain holes at door and side sill.
When repairing corroded areas, refer to the Corrosion Repair Manual.

SBT014A
Active Head RestraintNJBT0032The active head restraint system is designed so that the headrest
instantaneously moves towards the front upper direction by utiliz-
ing the force at the seatback during a rear-end collision.
As a result, the occupant's head is protected from being
overextended, reducing the chance for neck injury as much as
possible.
Seat with active head restraint have the labels shown in figures at
left.
SBT888
OPERATION OUTLINENJBT0032S01When the seatback receives a sharp backward force during a rear-
end collision, the input plate moves with the link rotating center as
a pivot. The headrest will then move towards the front upper direc-
tion with the center of the sliding roller as a pivot.
As the backward force on the seat back is eliminated, spring ten-
sion returns the headrest to its original position.

ratio feedback correction factor per cycle.+When the engine is stopped, a cer-
tain value is indicated.
+This data also includes the data for
the air-fuel ratio learning control.

[ÉC] or [ÉF]jj+The engine coolant temperature (deter-
mined by the signal voltage of the engine
coolant temperature sensor) is displayed.+When the engine coolant tempera-
ture sensor is open or short-
circuited, ECM enters fail-safe

ture determined by the ECM is dis-
played.
