1 CHECK TCM POWER SOURCE
1. Turn ignition switch to ªONº position.
(Do not start engine.)
2. Check voltage between TCM terminals 10, 19, 28 and ground.
Voltage: Battery voltage
3. Turn ignition switch to ªOFFº position.
4. Check voltage between TCM terminal 28 and ground.
Voltage: Battery voltage

OK or NG
OK©GO TO 2.
NG©Check the following items:
+Harness for short or open between ignition switch and TCM terminals 10, 19 and 25
(Main harness)
+Ignition switch and fuse
Refer to EL section (ªPOWER SUPPLY ROUTINGº).
2 CHECK TCM GROUND CIRCUIT
1. Turn ignition switch to ªOFFº position.
2. Disconnect TCM harness connector.
3. Check continuity between terminals 25, 48 and ground.
Continuity should exist.

SAT255K
DIAGNOSTIC TROUBLE CODE (DTC) CONFIRMATION
PROCEDURE
NLAT0032S03CAUTION:
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.
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 ªCVTº with CONSULT-II.
2) Make sure that output voltage of CVT fluid temperature sen-
sor is within the range below.
FLUID TEMP SEN: 0.5 - 1.5V
If out of range, drive the vehicle to decrease the voltage
(warm up the fluid) or stop engine to increase the voltage
(cool down the fluid)
3) Select ªDATA MONITORº mode for ªENGINEº with CONSULT-
II.
4) Start engine and maintain the following conditions for at least
15 consecutive seconds.
VHCL SPEED SE: 10 km/h (6 MPH) or more
THRTL POS SEN: More than 1.0/8
Selector lever: D position
ENG SPEED: 450 rpm or more
If the check result is ªNGº, go to ªDiagnostic Procedureº, AT-70.
With GST
Follow the procedure ªWith CONSULT-IIº.
