CHASSIS AND BODY MAINTENANCEPFP:00100
Checking Exhaust SystemALS000FG
Check exhaust pipes, muffler and mounting for improper attachment,
leaks, cracks, damage, chafing or deterioration.
Checking A/T FluidALS000GB
1. Warm up engine.
2. Check for fluid leakage.
3. Remove the tightening bolt for ATF level gauge.
4. Before driving, fluid level can be checked at fluid temperatures of 30 to 50°C (86 to 122°F) using “COLD”
range on ATF level gauge as follows.
a. Park vehicle on level surface and set parking brake.
b. Start engine and move selector lever through each gear position. Leave selector lever in “P” position.
c. Check fluid level with engine idling.
d. Remove ATF level gauge and wipe clean with lint-free paper.
CAUTION:
When wiping away the fluid level gauge, always use lint-free paper, not a cloth one.
e. Re-insert ATF level gauge into charging pipe as far as it will go.
CAUTION:
To check fluid level, insert the ATF level gauge until the cap contacts the end of the charging pipe,
with the gauge reversed from the normal attachment conditions.
f. Remove ATF level gauge and note reading. If reading is at low side of range, add fluid to the charging
pipe.
CAUTION:
Do not overfill.
5. Drive vehicle for approximately 5 minutes in urban areas.
6. Make the fluid temperature approximately 65°C (149°F).

NOTE:
Fluid level will be greatly affected by temperature as shown in figure. Therefore, be certain to per-
form operation while checking data with CONSULT-II.
a. Connect CONSULT-II to data link connector.
b. Select “MAIN SIGNALS” in “DATA MONITOR” mode for “A/T” with CONSULT-II.
c. Read out the value of “ATF TEMP 1”.
7. Re-check fluid level at fluid temperatures of approximately 65°C (149°F) using “HOT” range on A/T fluid
level gauge.
CAUTION:

When wiping away the fluid level gauge, always use lint-free paper, not a cloth one.

To check fluid level, insert the A/T fluid level gauge until
the cap contacts the end of the A/T fluid charging pipe,
with the gauge rotated from the normal attachment condi-
tions as shown.
8. Check fluid condition.

If fluid is very dark or smells burned, check operation of A/T.
Flush cooling system after repair of A/T.

If ATF contains frictional material (clutches, bands, etc.),
replace radiator and flush cooler line using cleaning solvent
and compressed air after repair of A/T. Refer to CO-14,
"RADIATOR" , CO-39, "RADIATOR" .
9. Install the removed A/T fluid level gauge in the A/T fluid charging pipe.

Changing A/T FluidALS000GC
1. Warm up ATF.
2. Stop engine.
3. Remove the tightening bolt for ATF level gauge.
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 stipu-
lated 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 deterio-
ration in driveability and automatic transmission durability, and may damage the automatic
transmission, 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 MA-28, "
Checking A/T Fluid" . If fluid is still dirty, repeat step 2.
through 5.
7. Install the removed ATF level gauge in the fluid charging pipe.
Checking Transfer FluidALS000GD
Check for oil leakage and oil level.
CAUTION:
Never start engine while checking oil level.ATF: Genuine NISSAN Matic J ATF

Removal and Installation of IPDM E/RAKS005SM
REMOVAL
1. Remove battery. Refer to SC-9, "Removal and Installation" in “Starting and Charging System (SC)” sec-
tion.
2. Remove IPDM E/R cover A. While pressing pawl on backside of
IPDM E/R cover B toward vehicle front to unlock, lift up IPDM E/
R.
3. While pressing pawls on right and left side of IPDM E/R, remove
IPDM E/R cover B from IPDM E/R.
4. Remove harness connector from IPDM E/R.
INSTALLATION
Install in the reverse order of removal.
