< PRECAUTION >
PRECAUTIONS
5. When the repair work is completed, return the ignition switch to the ″LOCK ″ position before connecting
the battery cables. (At this time, the steering lock mechanism will engage.)
6. Perform a self-diagnosis check of a ll control units using CONSULT-III.
Precaution for On Board Diagnosis (OBD) System of A/T and EngineINFOID:0000000001531485
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 negative battery cable before any repair
or inspection work. The open/short circuit of related switches, sensors, solenoid valves, etc. Will
cause the MIL to light up.
• Be sure to connect and lock the connectors secure ly 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 th e 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 afte r work. A misconnected or disconnected rubber tube
may cause the MIL to light up due to a malfunction of the EGR system or fuel injection system, etc.
• Be sure to erase the unnecessary malfunction informa tion (repairs completed) from the TCM and
ECM before returning the vehicle to the customer.
PrecautionINFOID:0000000001531486
NOTE:
If any malfunctions occur in the RE5R05A model tr ansmission, replace the entire transmission assem-
bly.
• Before connecting or disconn ecting the TCM harness connec-
tor, turn ignition switch “O FF” and disconnect negative bat-
tery cable. Because battery voltage is applied to TCM even if
ignition switch is turned “OFF”.
• After performing each TROUBLE DIAGNOSIS, perform “DTC
(Diagnostic Trouble Code) CONFIRMATION PROCEDURE”.
If the repair is completed the DTC should not be displayed in the
“DTC CONFIRMATION PROCEDURE”.
• Always use the specified brand of ATF. Refer to MA-12, "
Fluids and Lubricants".
• Use paper rags not cloth rags during work.
• After replacing the ATF, dispose of the waste oil using the methods prescribed by law, ordinance, etc.
• Before proceeding with disassembly, thoroughly clean the outside of the transmission. It is important to pre- vent the internal parts from becoming cont aminated by dirt or other foreign matter.
• Disassembly should be done in a clean work area.
• Use lint-free cloth or towels for wiping parts clean. Common shop rags can leave fibers that could interfere
with the operation of the transmission.
• Place disassembled parts in order for easier and proper assembly.

A/T FLUID
Changing the A/T Fluid (ATF)
INFOID:0000000004917425
CAUTION:
If using the vehicle for towing, the A/T fl uid must be replaced as specified. Refer to MA-8, "
Introduc-
tion of Periodic Maintenance".
1. Drive the vehicle to warm up the A/T fluid to approximately 80 ° C (176 ° F).
2. Stop the engine.
3. Remove the A/T fluid level gauge.
4. Drain the A/T fluid from the drain plug hole, then install the drain plug with a new gasket. Refill the transmission with new A/T
fluid. Always refill with the same volume as the drained A/T fluid.
Use the A/T fluid level gauge to check the A/T fluid level as
shown. Add A/T fluid as necessary.
• To flush out the old A/T fluid from the transmission oil coolers, pour new A/T fluid into the A/T fluid charg-
ing pipe with the engine idling and at the same time drain the old A/T fluid from the auxiliary transmis-
sion oil cooler hose return line.
• When the color of the A/T fluid coming out of the auxiliary transmission oil cooler hose return line is
about the same as the color of the new A/T fluid, flushing out the old A/T fluid is complete. The amount
of new A/T fluid used for flushing should be 30% to 50% increase of the specified capacity.
CAUTION:
• Use only Genuine NISSAN Matic J ATF and do not mix with other fluids.
• Using A/T fluid other than Genuine NISSAN Mati c J ATF will cause deterioration in driveability
and automatic transmission durability, and may damage the automatic transmission, which is
not covered by the warranty.
• When filling the transmission with A/T fluid, do not spill the A/T fluid on any heat generating parts such as the exhaust manifold.
• Do not reuse the drain plug gasket.
5. Install the A/T fluid level gauge and tighten the A/T fluid level gauge bolt to specification.
6. Drive the vehicle to warm up the A/T fluid to approximately 80 ° C (176 ° F).
7. Check the fluid level and condition. If the A/T fluid is still dirty, repeat steps 2 through 6.
8. Install the A/T fluid level gauge in the A/T fluid charging pipe and install the A/T fluid level gauge bolt.
9. Tighten the A/T fluid level gauge bolt to specification. Drain plug : Refer to
TM-220, "
Component".
