and roadability.

The construction and operation of the transaxle is the same as the 1989 626 EC-AT (G4A-EL). The Con-
struction and operation of the transfer unit and carrier are basically the same as the 1989 323 with 4WD.
The electronic control system of EC-AT is the same as the 1989 626 EC-AT (G4A-EL) non-turn0 model.
l
The center differential employs a planetary carrier system, and functions to distribute the driving force
to the front and rear differentials.

The electronically controlled, lockable center differential means all driving conditions are easily contended
with; from good road to bad roads and inclement weather.
l
To improve serviceability, the EC-AT control unit diagnoses malfunctions of the major electrical compo-
nents and outputs memorized malfunction codes by coded flashing of the HOLD indicator
The diagnosis connector is installed in the engine compartment by the left side suspension tower.

The 1990 323 4WD EC-AT also has a shift-lock system for improved safety.
