Data are reference values.
NOTE:
Make sure that the pointer swings only momentarily because the output time is so short. If the inspection is done with an oscilloscope, it
should be observed that the power source voltage lasts for 3.5 to 10 ms.

A/T SHIFT LOCK SYSTEM

Component InspectionBCS00153
SHIFT LOCK SOLENOID
Check operation by applying battery voltage to A/T device harness
connector terminal.
CAUTION:
Be sure to apply the voltage of the correct polarity to the
respective terminals. Otherwise, the part may be damaged.
DETENTION SWITCH (FOR KEY)
Check continuity between terminals of A/T device harness connector
terminals.
DETENTION SWITCH (FOR SHIFT)
Check continuity between terminals of A/T device harness connector
terminals.
KEY LOCK SOLENOID
Key Lock (With Intelligent Key)
Check operation by applying battery voltage to ignition knob switch,
key switch and key lock solenoid harness connector terminal.
CAUTION:
Be careful not to cause burnout of harness.

3. Disconnect terminal cord assembly harness connector.
4. Remove snap ring from terminal body.
5. Remove terminal cord assembly by pushing terminal body into
transaxle case.
6. Remove engine under cover.
7. Remove front LH nut of front suspension member, and then
lower front LH of front suspension member to secure a space for
removing control valve assembly.
8. Drain ATF from A/T. Refer to AT- 1 5 , "
Changing A/T Fluid" .
9. Remove oil pan and oil pan gasket.
10. Check foreign materials in oil pan to help determine causes of
malfunction. If the ATF is very dark, smells burned, or contains
foreign particles, frictional material (clutches, band) may need
replacement. A tacky film that will not wipe clean indicates var-
nish build up. Varnish can cause valves, servo, and clutches to
stick and can inhibit pump pressure.

If frictional material is detected, replace radiator after
repair of A/T. Refer to CO-13, "
RADIATOR" , CO-16,
"RADIATOR (ALUMINUM TYPE)" (QR engine) or CO-37,
"RADIATOR" , CO-40, "RADIATOR (ALUMINUM TYPE)"
(VQ engine).
11. Remove control valve assembly fixing bolts A, B and C .

CAUTION:

Do not reuse O-ring.

Apply petroleum jelly to O-ring.

Be careful not to mis-connect because shape of connectors
are same as turbine revolution sensor (power train revolu-
tion sensor).
NOTE:
For prevent mis-connection, revolution sensor harness connec-
tor is color taped for identification.
