DIAGNOSIS

Operating problems in the AISIN electronic automatic transmission may be caused by the engine, c o n -
trol system or automatic transmission itself.
The fault-finding procedure begins with very simple operations, carried out in order of difficulty, initially
aimed at establishing whether the fault depends on the engine, control system or gearbox.
Electrical faults are revealed by the self-test funcction of the control module, by the flashing of the red
light on the instrument panel.

Preliminary tests

Checking oil level

NOTE The gearbox oil level must be checked with the engine and gearbox at normal operating
atures (gearbox oil: 70 - 80°C), so the vehicle must be driven for a suitable period of time before
the check.

To check the level of the gearbox oil, proceed as
follows:
- park the vehicle on flat ground and apply the
handbrake;
- w i t h the engine idling, gently move the selec-
tor lever from position P to position 1, then re-
turn it to P;
- withdraw the dipstick (1) and clean it;
- insert the dipstick fully into its seating;
- withdraw the dipstick again and check that the
oil level lines up with the notch on the side of
the stick marked HOT.
If the oil level is low, identify and eliminate the
leaks, then top up the level.
Also check the condition of the oil; if is black or
smells burnt, it should be changed.

Checking selector lever position

When the selector lever is moved from position N
to the other positions, check that it moves freely
without stiffness into any position, and that the
position indicator on the instrument panel indi-
cates the correct position.

Checking starter switch

If the engine does not start when the selector
lever is at position N or P, or vice versa it starts
when the lever is in a position other than N or P,
the selector lever control cable must be adjusted
as described on page 45, by adjusting the head
(1) and locking it with the locknut (2). Finally
check the correct position of the selector lever
position sensor as described on page 47.
