TROUBLE DIAGNOSIS
Revision: June 20062007 Versa
ACTIVE TEST
CAUTION:

Do not perform active test while driving.

Make sure to completely bleed air from the brake system.

The ABS and brake warning lamps turn on during the active test.
Operation Procedure
1. Connect the CONSULT-II and CONSULT-II CONVERTER to the data link connector and start the engine.
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carries out CAN communication.
2. Touch “START (NISSAN BASED VHCL)” on the display screen.
3. Touch “ABS”.
If “ABS” is not indicated, go to GI-40, "
CONSULT-II Data Link Connector (DLC) Circuit" .
4. Touch “ACTIVE TEST”.
5. The SELECT TEST ITEM screen is displayed.
6. Touch necessary test item.
7. With the “MAIN SIGNALS” display selected, touch “START”.
8. The Active Test screen will be displayed, so conduct the following test.
Solenoid Valve Operation Chart
NOTE:

If active test is performed with brake pedal depressed, pedal stroke may change. This is normal.

“TEST IS STOPPED” is displayed approximately 10 seconds after operation starts.

After “TEST IS STOPPED” is displayed, to perform test again, repeat Step 6.
ABS Motor
Touch “ON” and “OFF” on the screen. Check that ABS motor relay
operates as shown in table below.
NOTE:

If active test is performed with brake pedal depressed, pedal
stroke may change. This is normal.

“TEST IS STOPPED” is displayed approximately 10 seconds
after operation starts.

Precautions UCS005XJ
NOTE:
If any malfunction occurs in the RE0F08A model transaxle, replace the entire transaxle assembly.

Before connecting or disconnecting the TCM harness con-
nector, turn ignition switch OFF and disconnect negative
battery cable. Because battery voltage is applied to TCM
even if ignition switch is turned OFF.

When connecting or disconnecting pin connectors into or
from TCM, take care not to damage pin terminals (bend or
break).
When connecting pin connectors make sure that there are
not any bends or breaks on TCM pin terminal.

Before replacing TCM, perform TCM input/output signal
inspection and make sure whether TCM functions properly
or not. CVT-54, "
TCM INSPECTION TABLE".

After performing each TROUBLE DIAGNOSIS, perform
“DTC Confirmation Procedure”.
If the repair is completed the DTC should not be displayed
in the “DTC Confirmation Procedure”.

Always use the specified brand of CVT fluid. Refer to MA-11,
"Fluids and Lubricants" .

Use lint-free paper, not cloth rags, during work.

After replacing the CVT fluid, dispose of the waste oil using the
methods prescribed by law, ordinance, etc.
Service Notice or PrecautionsUCS005XK
CVT FLUID COOLER SERVICE
If CVT fluid contains friction material (clutches, brakes, etc.), or if an CVT is replaced, inspect and clean the
CVT fluid cooler mounted in the radiator or replace the radiator. Flush cooler lines using cleaning solvent and
compressed air after repair. For CVT fluid cooler cleaning procedure, refer to CVT-18, "
CVT Fluid Cooler
Cleaning" . For radiator replacement, refer to CO-11, "RADIATOR" .
