SELF-DIAGNOSTIC PROCEDURE
(WITH CONSULT-II)
NCAT0022S021. Turn on CONSULT-II and touch ªENGINEº for OBD detected
items or touch ªCVTº for TCM self-diagnosis.
If CVT is not displayed, check TCM power supply and ground
circuit. Refer to AT-41. If result is NG, refer to EL section
(ªPOWER SUPPLY ROUTINGº).
2. Touch ªSELF DIAGNOSISº.
Display shows malfunction experienced since the last erasing
operation.
CONSULT-II performs REAL-TIME SELF-DIAGNOSIS.
Also, any malfunction detected while in this mode will be dis-
played at real time.

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
ª-2º is selected, that might cause the abnormality of drivabil-
ity.

Refer to EC section [ªMalfunction Indicator (MI)º, ªON BOARD
DIAGNOSTIC SYSTEM DESCRIPTIONº].
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.
