DescriptionNJAT0315The overrun clutch solenoid valve is activated by the TCM in
response to signals sent from the inhibitor switch, overdrive con-
trol switch, vehicle speed and throttle position sensors. The over-
run clutch operation will then be controlled.

DIAGNOSTIC TROUBLE CODE (DTC) CONFIRMATION
PROCEDURE
NJAT0315S03CAUTION:
Always drive vehicle at a safe speed.
NOTE:
If ªDIAGNOSTIC TROUBLE CODE CONFIRMATION PROCE-
DUREº has been previously conducted, always turn ignition
switch ªOFFº and wait at least 5 seconds before conducting
the next test.
TESTING CONDITION:
Always drive vehicle on a level road to improve accuracy of
test.
After the repair, perform the following procedure to confirm the
malfunction is eliminated.
With CONSULT-II
1) Turn ignition switch ªONº and select ªDATA MONITORº mode
for ªENGINEº with CONSULT-II.
2) Start engine.
3) Accelerate vehicle to a speed of more than 10 km/h (6 MPH)
with ªDº position (OD ªONº).
4) Release accelerator pedal completely with ªDº position (OD
ªOFFº).
