2. CHECK PNP SWITCH CIRCUIT (WITHOUT CONSULT-II)
Without CONSULT-II
1. Turn ignition switch ON. (Do not start engine.)
2. Check voltage between TCM harness connector terminals and
ground while moving selector lever through each position. Refer
to AT- 1 6 8 , "

Adjustment of A/T Position" .
4. CHECK VEHICLE SPEED SENSOR·A/T AND VEHICLE SPEED SENSOR·MTR CIRCUIT
Check vehicle speed sensor·A/T (revolution sensor) and vehicle speed sensor·MTR circuit. Refer to AT- 8 0 ,
"VEHICLE SPEED SENSOR·A/T (REVOLUTION SENSOR)" and AT- 8 6 , "VEHICLE SPEED SENSOR MTR"
.
OK or NG
OK >> GO TO 5.
NG >> Repair or replace vehicle speed sensor·A/T (revolution sensor) and/or vehicle speed sensor·MTR
circuits.

3. Disconnect terminal cord assembly harness connector.
4. Remove snap ring from terminal body.
5. Remove terminal cord assembly by pushing terminal body into
transaxle case.
6. Remove engine under cover.
7. Remove front LH nut of front suspension member, and then
lower front LH of front suspension member to secure a space for
removing control valve assembly.
8. Drain ATF from A/T. Refer to AT- 1 5 , "
Changing A/T Fluid" .
9. Remove oil pan and oil pan gasket.
10. Check foreign materials in oil pan to help determine causes of
malfunction. If the ATF is very dark, smells burned, or contains
foreign particles, frictional material (clutches, band) may need
replacement. A tacky film that will not wipe clean indicates var-
nish build up. Varnish can cause valves, servo, and clutches to
stick and can inhibit pump pressure.

If frictional material is detected, replace radiator after
repair of A/T. Refer to CO-13, "
RADIATOR" , CO-16,
"RADIATOR (ALUMINUM TYPE)" (QR engine) or CO-37,
"RADIATOR" , CO-40, "RADIATOR (ALUMINUM TYPE)"
(VQ engine).
11. Remove control valve assembly fixing bolts A, B and C .

CAUTION:
When replacing or cleaning refrigerant cycle components, observe the following.

When the compressor is removed, store it in the same way at it is when mounted on the car. Fail-
ure to do so will cause lubricant to enter the low-pressure chamber.

When connecting tubes, always use a torque wrench and a back-up wrench.

After disconnecting tubes, immediately plug all openings to prevent entry of dirt and moisture.

When installing an air conditioner in the vehicle, connect the pipes at the final stage of the opera-
tion. Never remove the seal caps of pipes and other components until just before required for con-
nection.

Allow components stored in cool areas to warm to working area temperature before removing seal
caps. This prevents condensation from forming inside A/C components.

Thoroughly remove moisture from the refrigeration system before charging the refrigerant.

Always replace used O-rings.

When connecting tubes, apply lubricant to circle of the O-rings shown in illustration. Be careful
not to apply lubricant to threaded portion.

O-ring must be closely attached to the groove of tube.

When replacing the O-ring, be careful not to damage O-ring and tube.

Connect tube until a click can be heard, then tighten the nut or bolt by hand until snug. Make sure
that the O-ring is installed to tube correctly.

After connecting line, perform leak test and make sure that there is no leakage from connections.
When the refrigerant leaking point is found, disconnect that line and replace the O-ring. Then
tighten connections of seal seat to the specified torque.
Precautions for Servicing CompressorBJS000F8

Plug all openings to prevent moisture and foreign matter from entering.

When the compressor is removed, store it in the same position at it is when mounted on the car.

When replacing or repairing compressor, follow “Maintenance of Lubricant Quantity in Compres-
sor” exactly. Refer to AT C - 2 1 , "
Maintenance of Lubricant Quantity in Compressor" .

Keep friction surfaces between clutch and pulley clean. If the surface is contaminated, with lubri-
cant, wipe it off by using a clean waste cloth moistened with thinner.

After compressor service operation, turn the compressor shaft by hand more than five turns in
both directions. This will equally distribute lubricant inside the compressor. After the compressor
is installed, let the engine idle and operate the compressor for one hour.Lubricant name : Nissan A/C System Oil Type S
