detected in self-diagnosis depending on control unit which perform CAN communication.

For details, refer to the separate “CONSULT-II Operations Man-
ual”.
1. Turn ignition switch “OFF”.
2. Connect CONSULT-II and CONSULT-II CONVERTER to data
link connector, which is located in instrument lower panel on
driver side.
3. Turn ignition switch “ON”. (Do not start engine.)
4. Touch “START (NISSAN BASED VHCL)”.
5. Touch “A/T”.
If “A/T” is not indicated, go to GI-40, "

6. Remove snap ring from A/T assembly harness connector.
7. Push A/T assembly harness connector.
CAUTION:
Be careful not to damage connector.
8. Remove oil pan and oil pan gasket.
9. Check foreign materials in oil pan to help determine causes of
malfunction. If the fluid is very dark, smells burned, or contains
foreign particles, the frictional material (clutches, band) may
need replacement. A tacky film that will not wipe clean indicates
varnish build up. Varnish can cause valves, servo, and clutches
to stick and can inhibit pump pressure.

If frictional material is detected, perform A/T fluid cooler
cleaning. Refer to AT- 1 4 , "
A/T Fluid Cooler Cleaning" .
10. Remove magnets from oil pan.
