4. CHECK SOLENOID, VDC CHANGE-OVER VALVE, ACTUATOR RELAY GROUND CIRCUIT

Check continuity between ABS actuator and electric unit (control
unit) harness connector E241 terminal 46 and ground.
OK or NG
OK >> Replace ABS actuator and electric unit (control unit).
NG >> Harness or connector is open or shorted. Repair or
replace malfunctioning components.

INSPECTION PROCEDURE
1. CHECK SELF-DIAGNOSTIC RESULTS
Check the self-diagnostic results.
Is above displayed on self-diagnosis display?
YES >> GO TO 2.
NO >> INSPECTION END
2. CHECK CONNECTOR
1. Turn ignition switch OFF, disconnect ABS actuator and electric unit (control unit) connector and stop lamp
switch connector, and check terminal for deformation, disconnection, looseness, and so on. If there is a
malfunction, repair or replace the terminal.
2. Securely reconnect connectors.
3. Start engine.
4. Repeat pumping brake pedal carefully several times, and then perform self-diagnosis again.
OK or NG
OK >> Connector terminal contact is loose, damaged, open or shorted.
NG >> GO TO 3.

e. Install timing chain tensioner (primary).

Remove any dirt and foreign materials completely from the
back and the mounting surfaces of timing chain tensioner (pri-
mary).
f. Pull out stopper pin after installing, and then release plunger.
g. Make sure again that timing chain and water pump sprocket are
engaged.
4. Install chain tensioner cover and water pump cover as follows:
a. Before installing, remove all traces of old liquid gasket from mat-
ing surface of water pump cover and chain tensioner cover
using scraper. Also remove traces of old liquid gasket from the
mating surface of front timing chain case.
b. Apply a continuous bead of liquid gasket with tube presser [SST:
WS39930000] to mating surface of chain tensioner cover and
water pump cover.
Use Genuine Liquid Gasket or equivalent.
CAUTION:
Attaching should be done within 5 minutes after coating.
c. Tighten mounting bolts.
5. Install water drain plug (front) on water pump side of cylinder block.

Apply liquid gasket to the thread of water drain plug (front).
Use Genuine Liquid Gasket or equivalent.
6. Install in the reverse order of removal in this step.
NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal/installation, slack in guide may gen-
erate a pounding noise during and just after engine start. However, this does not indicate an unusualness.
Noise will stop after hydraulic pressure rises.
INSPECTION AFTER INSTALLATION

Check for leaks of engine coolant using radiator cap tester adapter [SST: EG17650301] and radiator cap
tester (commercial service tool). Refer to CO-34, "
LEAK CHECK" .

Start and warm up engine. Visually check if there is no leaks of engine coolant.

CVT SYSTEM

TCM FunctionBCS001G2
The function of the TCM is to:

Receive input signals sent from various switches and sensors.

Determine required line pressure, shifting point, and lock-up operation.

Send required output signals to the step motor and the respective solenoids.
CONTROL SYSTEM OUTLINE
The CVT senses vehicle operating conditions through various sensors. It always controls the optimum shift
position and reduces shifting and lock-up shocks.
