9. Set ªENGINE BRAKE LEVELº by touching ªUPº or ªDOWNº.
ENGINE BRAKE LEVEL
0: Initial set value (Engine brake level control is
activated)
OFF: Engine brake level control is disactivated.
10. Turn ignition switch ªOFFº, wait at least 5 seconds and then
turn ignition switch ªONº.
11. Engine brake level set is completed.
CAUTION:
Mode of ª+1º ª0º ª-1º ª-2º ªOFFº can be selected by pressing
the ªUPº ªDOWNº on CONSULT screen. However, do not
select mode other than ª0º and ªOFFº. If the ª+1º or ª-1º or

TCM Self-diagnostic Procedure (No Tools)=NCAT0022S0703Preparation
1. Turn ignition switch to ªOFFº position.
2. Disconnect the throttle position switch harness connector.
3. Turn ignition switch to ªONº position.
4. Check continuity of the closed throttle position switch.
Continuity should exist.
(If continuity does not exist, check throttle opener and
closed throttle position switch. Then increase vacuum
until closed throttle position switch shows continuity.)
5. Connect the throttle position switch harness connector.
6. Warm up the engine.
7. Turn the ignition switch from ON to OFF two more times, and
then turn to OFF.
8. In the ªPº position of the selector lever, turn the ignition switch
ON, and verify that the CVT warning lamp turns on for about
2 seconds.
9. Turn the ignition switch OFF.
10. Press the brake pedal, and shift the selector lever to the ªDº
position.
11. Turn the ignition switch ON.
12. Release the brake, and shift the selector lever to the ªLº posi-
tion.
13. Fully depress both brake and accelerator pedals all the way to
the floor. Without releasing the brake and accelerator pedals,
shift the selector lever to the ªDº position.
14. Read the display from the CVT warning lamp to complete the
diagnosis.

IntroductionNCAT0023
The TCM receives a signal from the vehicle speed sensor, throttle
position sensor or PNP switch and provides shift control or lock-up
control via step motor and CVT solenoid valves.
The TCM also communicates with the ECM by means of a signal
sent from sensing elements used with the OBD-related parts of the
CVT system for malfunction-diagnostic purposes. The TCM is
capable of diagnosing malfunctioning parts while the ECM can
store malfunctions in its memory.
Input and output signals must always be correct and stable in the
operation of the CVT system. The CVT system must be in good
operating condition and be free of valve seizure, solenoid valve
malfunction, etc.
It is much more difficult to diagnose a problem that occurs intermit-
tently rather than continuously. Most intermittent problems are
caused by poor electric connections or improper wiring. In this
case, careful checking of suspected circuits may help prevent the
replacement of good parts.
A visual check only may not find the cause of the problems. A road
test with CONSULT-II (or GST) or a circuit tester connected should
be performed. Follow the ªWork Flowº. Refer to AT-32.
Before undertaking actual checks, take a few minutes to talk with
a customer who approaches with a driveability complaint. The cus-
tomer can supply good information about such problems, espe-
cially intermittent ones. Find out what symptoms are present and
under what conditions they occur. A ªDiagnostic Worksheetº like the
example (AT-31) should be used.
Start your diagnosis by looking for ªconventionalº problems first.
This will help troubleshoot driveability problems on an electronically
controlled engine vehicle.
Also check related Service bulletins for information.
