Wheel Sensor System EFS006LQ
INSPECTION PROCEDURE
1. CONNECTOR INSPECTION
Disconnect the ABS actuator and electric unit (control unit) connector E33 and wheel sensor of malfunctioning
code.
Check the terminals for deformation, disconnection, looseness or damage.
OK or NG
OK >> GO TO 2.
NG >> Repair or replace as necessary.
2. CHECK WHEEL SENSOR OUTPUT SIGNAL
1. Connect ABS active wheel sensor tester (J-45741) to wheel sensor using appropriate adapter.
2. Turn on the ABS active wheel sensor tester power switch.
NOTE:
The green POWER indicator should illuminate. If the POWER indicator does not illuminate, replace the
battery in the ABS active wheel sensor tester before proceeding.
3. Spin the wheel of the vehicle by hand and observe the red SENSOR indicator on the ABS active wheel
sensor tester. The red SENSOR indicator should flash on and off to indicate an output signal.
NOTE:
If the red SENSOR indicator illuminates but does not flash, reverse the polarity of the tester leads and
retest.
Does the ABS active wheel sensor tester detect a signal?
YES >> GO TO 3.
NO >> Replace the wheel sensor. Refer to BRC-33, "
Removal and Installation" .
3. CHECK TIRES
Check for inflation pressure, wear and size of each tire. Refer to WT-29, "
SERVICE DATA AND SPECIFICA-
TIONS (SDS)" .
Are tire pressure and size correct and is tire wear within specifications?
YES >> GO TO 4.
NO >> Adjust tire pressure or replace tire(s).
4. CHECK WHEEL BEARINGS
Check wheel bearing axial end play. Refer to FAX-5, "
FRONT WHEEL BEARING INSPECTION" or RAX-4,
"REAR WHEEL BEARING INSPECTION" .
OK or NG
OK >> GO TO 5.
NG >> Repair or replace as necessary. Refer to FAX-5, "
Removal and Installation" or RAX-4, "Removal
and Installation" .

Revision: June 20062007 Versa
Precautions for On Board Diagnostic (OBD) System of CVT and EngineUCS005XG
The ECM has an on board diagnostic system. It will light up the malfunction indicator lamp (MIL) to warn the
driver of a malfunction causing emission deterioration.
CAUTION:
Be sure to turn the ignition switch OFF and disconnect the battery cable from the negative termi-
nal before any repair or inspection work. The open/short circuit of related switches, sensors, sole-
noid valves, etc. will cause the MIL to light up.
Be sure to connect and lock the connectors securely after work. A loose (unlocked) connector will
cause the MIL to light up due to an open circuit. (Be sure the connector is free from water, grease,
dirt, bent terminals, etc.)
Be sure to route and secure the harnesses properly after work. Interference of the harness with a
bracket, etc. may cause the MIL to light up due to a short circuit.
Be sure to connect rubber tubes properly after work. A misconnected or disconnected rubber tube
may cause the MIL to light up due to a malfunction of the EVAP system or fuel injection system,
etc.
Be sure to erase the unnecessary malfunction information (repairs completed) from the TCM and
ECM before returning the vehicle to the customer.
Service After Replacing TCM and Transaxle Assembly UCS006L3
SERVICE AFTER REPLACING TCM AND TRANSAXLE ASSEMBLY
Perform the applicable service in the following sheet when replacing TCM or transaxle assembly
CAUTION:
Do not start the engine until the service is completed.
“A/T C/U POWER SUPPLY [P1701]” may be indicated soon after replacing TCM or transaxle
assembly (after erasing the memory at the pattern B). Restart the self-diagnosis after erasing the
self-diagnosis result. Check that no error is detected.
NOTE:
Old unit means that the unit has been already used for another vehicle.
PATTERN A
1. Shift the selector lever to “P” position after replacing TCM. Turn the ignition switch ON.
2. Check that the shift position indicator in the combination meter turns ON (It indicates approximately 1 or 2
seconds after turning the ignition switch ON.)
Check the following items if the shift position indicator does not turn ON. Repair or replace the shift
position indicator if necessary.
–The harness between TCM and ROM ASSY in the transaxle assembly is open or short.
–Cable disconnected, loosen, or bent from the connector housing.
PATTERN B
1. Turn the ignition switch ON after replacing each part.
2. Connect CONSULT-II connector to data link connector. Refer to GI-38, "
CONSULT-II Start Procedure" .
3. Start engine.
CAUTION:
Do not start the driving.
4. Touch CONSULT-II screen in the order of “START (NISSAN BASED VHCL)”, “TRANSMISSION”, “DATA
MONITOR”, and “MAIN SIGNALS”.
5. Warm up the transaxle assembly until “ATF TEMP” indicates 48 (approximately 20°C) or more. Turn the
ignition switch OFF.
