When more than one malfunctions are detected, a maximum of 3 code numbers can be stored;
the latest malfunction will be displayed first.
6. Check ACS-40, "
Diagnostic Trouble Code (DTC) Chart" , and repair or replace if necessary.
7. After repair, erase DTC stored in the ICC unit.
8. DTC 55 will be shown.
9. Turn ignition switch OFF to exit the diagnosis.
10. Perform ICC system running test (drive vehicle with ICC system ON), and make sure that ICC warning
lamp does not illuminate.
Self-Diagnostic Erasing Method
1. Stop the vehicle and turn the ignition switch OFF.
2. Turn ignition switch ON and start self-diagnosis.
3. During self-diagnosis mode, press CANCEL switch 5 times, and DISTANCE switch 5 times in this order.
CAUTION:

Press them within 10 seconds after pressing CANCEL switch at first.

When operation is not completed within 10 seconds, start again from above go to 2.
4. DTC 55 will be shown.
CAUTION:
DTC of an existing malfunction will not be erased.
5. Turn ignition switch OFF to exit the diagnosis.
6. Perform ICC system running test (drive vehicle with ICC system ON), and make sure that ICC system
warning lamp (yellow) does not illuminate.
SELF-DIAGNOSIS BY ICC SYSTEM DISPLAY WILL NOT RUN.

A/T FLUIDPFP:KLE40
Changing A/T FluidACS0079Z
1. Warm up ATF.
2. Stop engine.
3. Loosen the level gauge bolt.
4. Drain ATF from drain plug and refill with new ATF. Always refill
same volume with drained fluid.

To replace the ATF, pour in new fluid at the charging pipe with
the engine idling and at the same time drain the old fluid from
the radiator cooler hose return side.

When the color of the fluid coming out is about the same as
the color of the new fluid, the replacement is complete. The
amount of new transmission fluid to use should be 30 to 50%
increase of the stipulated amount.
CAUTION:

Use only Genuine Nissan Matic J ATF. Do not mix with other fluid.

Using automatic transmission fluid other than Genuine Nissan Matic J ATF will cause deteriora-
tion in drive ability and automatic transmission durability, and may damage the automatic trans-
mission, which is not covered by the warranty.

When filling ATF, take care not to splash heat generating parts such as exhaust with ATF.

Do not reuse drain plug gasket.
5. Run engine at idle speed for 5 minutes.
6. Check fluid level and condition. Refer to AT- 1 2 , "
Checking A/T Fluid" . If fluid is still dirty, repeat step 2
through 5.
7. Install the removed A/T fluid level gauge in the A/T fluid charging pipe.
8. Tighten the level gauge bolt.
Checking A/T FluidACS007A0
1. Warm up engine.
2. Check for fluid leakage.
3. Loosen the level gauge bolt.
4. Before driving, fluid level can be checked at fluid temperatures
of 30 to 50°C (86 to 122°F) using “COLD” range on A/T fluid
level gauge as follows.
a. Park vehicle on level surface and set parking brake.
b. Start engine and move selector lever through each gear posi-
tion. Leave selector lever in “P” position.
c. Check fluid level with engine idling.
d. Remove A/T fluid level gauge and wipe clean with lint-free
paper.
CAUTION:
When wiping away the A/T fluid level gauge, always use
lint-free paper, not a cloth one.A/T fluid: Genuine Nissan Matic J ATF

A/T CONTROL SYSTEM
Revision: 2004 November 2004 FX35/FX45
TCM FunctionACS002LF
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.

CAN CommunicationACS004PB
SYSTEM DESCRIPTION
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only. For details, refer to LAN-6,
