TOROUE CONVERTER
Full Lock-up
. Lock-up Control Solenoid Valve A: ON
. Lock-up Control Solenoid Valve B: ON
o Linear Solenoid Pressure: High
When the vehicle speed further increases. the linear
solenoid pressure is increased to high in accordance
with the linear solenoid controlled bv the PCM.
The lock-up timing valve overcomes the spring force
and moves to the left side. Also, this valve closes the
fluid port leading to the left side of the lock-up control
Under this condition. the modulator pressure in the left
side of the lock-up control valve had already been
released by the lock-up control solenoid valve B; the
lock-up control valve js moved to the left side. As this
takes place, the torque converter back pressure is
released fully. causing the lock-up clutch to be engaged
fully.

on the hvdraulic circuit.

-lgnition Timing Inspection and Setting
1.Check the idle speed, and adjust it it necessary (see
section 'l '1 ).
Pull out the service check connector 2P (BRN and BLK
wires) from the connector holder located under the
dash on the front passenger side, then connect the
SCS service connector (T/N 07PAZ - 0010'100) to it.
Start the engine. Hold the engine at 3.000 rpm with
no load {A,/T in E or E. M/T in neutral) until the
radiator fan comes on, then let it idle.
Connect the timing light to the No. 1 ignition wire,
then point the light toward the pointer on the timing
belt cover.
Check the ignition timing in no load conditions:
headlights. blower fan, rear window defogger, and
air conditioner are not operating.

6. Adjust the ignition timing if necessary, as follows.
Loosen the distributor mounting bolts. and turn the
distributor ignition (Dl) housing counterclockwise to
advance the timing, or clockwise to retard the tim-
ing.

Tighten the distributor mounting bolts, and recheck
the ignition timing.
Disconnect the SCS service connector from the ser-
vice check connector.

Removal:
1. Disconnect the connector from the distributor.
2. Disconnect the ignition wires from the distributor
ignition {Dl) cap.
3. Remove the mounting bolts from the distributor,
then remove the distributor from the cylinder head.

MOUNTING BOLT18 N.m 11.8 kgtm, 13lbf.ltl
lnstallation:
NOTE: Before you install the distributor. bring the No. 1
piston to compression stroke TDC.
1. Coat a new O-ring with engine oil, then install it.
2. Slip the distributor into position
NOTE: The lug on the end of the distributor and its
mating grooves in the camshaft end are both offset
to eliminate the possibility of installing the distribu-
tor 180" out of time.
3. Installthe mounting bolts, and tighten them lightly.
