DIAGNOSTIC PROCEDURE WITH DIAGNOSTIC TROUBLE CODE (DTC)
AUTOMATIC TRANSMISSION (DIAGNOSTICS)
7 CHECK LOW CLUTCH TIMING SOLENOID
(IN TRANSMISSION).
1) Remove transmission connector from
bracket.
2) Lift-up or raise the vehicle and support with
safety stand.
3) Drain automatic transmission fluid.
CAUTION:
Do not drain the automatic transmission flu-
id until it cools down.
4) Remove oil pan, and disconnect connector
from low clutch timing solenoid.
5) Measure resistance between low clutch
timing solenoid connector and transmission
ground.
Terminal
No. 1 — Transmission ground:
Is the measured value within the specified
range?
8 CHECK HARNESS CONNECTOR BETWEEN
LOW CLUTCH TIMING SOLENOID AND
TRANSMISSION.
Measure resistance of harness between low
clutch timing solenoid and transmission con-
nector.
Connector & terminal
(AT9) No. 1 — (T4) No. 3:
Is the measured value less than the specified
value?
9 CHECK HARNESS CONNECTOR BETWEEN
LOW CLUTCH TIMING SOLENOID AND
TRANSMISSION.
Measure resistance of harness between low
clutch timing solenoid connector and transmis-
sion ground.
Connector & terminal
(T4) No. 3 — Transmission ground:
Does the measured value exceed the specified
value?

Go to step 8. Replace low clutch
timing solenoid.

clutch timing sole-
noid and transmis-
sion connector.

rary poor contact
of the connector or
harness may be
the cause. Repair

nector in low
clutch timing sole-
noid and transmis-
sion.
