INSPECT RESISTANCE OF TCC SOLENOID
VALVE
Inspect the resistance between TCC
•
solenoid valve (part-side) terminal A and
8
body ground.
Is the resistance within 11.6    16.6 ohms ?
•
(See SOLENOID VALVE INSPECTION
.)
INSPECT TCM CONNECTOR FOR POOR
CONNECTION
Disconnect the TCM connector.
•
9
Inspect for poor connection (such as
•
damaged/pulled-out pins, corrosion).
Are the connector and terminals normal?
•
INSPECT AT SOLENOID VALVE
CONNECTOR CIRCUIT FOR OPEN CIRCUIT
Inspect for continuity between the TCM
•
10
(wiring harness-side) terminal 2W and AT
solenoid valve connector (wiring harness-
side) terminal G.
Is there continuity between the terminals?

INSPECT AT SOLENOID VALVE
CONNECTOR CIRCUIT FOR SHORT TO
POWER SUPPLY
Turn the ignition switch to the ON position

connector (wiring harness-side) terminal G.
Is the voltage 0 V ?
•
INSPECT TCM CIRCUIT FOR SHORT TO
GROUND
Turn the ignition switch to the LOCK
•
position.
12
Inspect for continuity between the TCM
•
(wiring harness-side) terminal 2W and
body ground.
Is there continuity?
