A/T CONTROL SYSTEM
TCM FunctionBCS000ZP
The function of the TCM is to:
Receive input signals sent from various switches and sensors.
Determine required line pressure, shifting point, lock-up operation, and engine brake operation.
Send required output signals to the respective solenoids.
CONTROL SYSTEM OUTLINE
The automatic transmission senses vehicle operating conditions through various sensors or signals. It always
controls the optimum shift position and reduces shifting and lock-up shocks.

Abbreviations: I = Inspect and correct or replace as necessary, R = Replace
NOTE:
(1) If towing a trailer, using a camper or a car-top carrier, or driving on rough or muddy roads, inspect CVT fluid deterioration with
CONSULT-II every 90,000 km (54,000 miles), then change CVT fluid NS-2 if necessary. (Refer to CVT-46, "
Check CVT Fluid Dete-
rioration Date" .) And if CONSULT-II is not available, change (not just inspect) CVT fluid NS-2 every 90,000 km (54,000 miles).
Using transmission fluid other than Genuine Nissan CVT Fluid NS-2 will damage the CVT, which is not covered by the
warranty.
(2) Inspect once per year.

Conditions”. MAINTENANCE OPERATIONMAINTENANCE INTERVAL

RECOMMENDED FLUIDS AND LUBRICANTS
RECOMMENDED FLUIDS AND LUBRICANTSPFP:00000
Fluids and LubricantsBLS0009C
*1: For further details, see “SAE Viscosity Number”.
*2: Use Genuine NISSAN Anti-freeze Coolant or equivalent in its quality, in order to avoid possible aluminum corrosion within the engine
cooling system caused by the use of non-genuine engine coolant.
Note that any repairs for the incidents within the engine cooling system while using non-genuine engine coolant may not be
covered by the warranty even if such incidents occurred during the warranty period.
*3: Contact a Nissan dealership for more information regarding suitable fluids, including recommended brand(s) of DEXRON
TM III/MER-
CONTM Automatic Transmission Fluid.
*4: Using transmission fluid other than Genuine NISSAN CVT Fluid NS-2 will damage the CVT, which is not covered by the war-
ranty.
*5: DEXRON
TM III type ATF can be used.
*6: Never mix different type of fluids (DOT 3 and DOT 4).Capacity (Approximate)
