GENERAL

OUTLINE OF CHANGES

Since the vehicles with the 4G93-MPI engine have been added, the V4AW4 type transmission has been
adopted. This transmission is basically the same as that of the vehicles with 4G94 engine. 
Due to the changes shown below, some new service procedures have been added.

D

On the vehicles with 4G93-MPI engine, the APS has been used for the transmission control (input
signal of the throttle opening angle). Due to this, the road test, the inspection procedures for diagnosis
codes, and the service data have been reviewed.

D

On the vehicles with 4G93-MPI engine, the shift pattern has been established. On the vehicles with
4G94 engine, the shift pattern has been changed.

D

On the vehicles with 4G93-MPI engine, the kick-down cable adjustment procedure has been established.

D

A full-time 4WD model has been added to the vehicles with 4G93-MPI engine (Refer to GROUP 22
–  Manual Transmission).

D

Due to the addition of a full-time 4WD model, the transfer control lever and the 4WD indicator control
unit on the vehicles with 4G93-MPI engine have been discontinued.

D

On all models, the quantity of the transfer oil has been changed from 2.3 litre to 2.2 litre.

D

On all models, the wide open throttle switch has been discontinued.

INSPECTION PROCEDURES FOR DIAGNOSIS CODES

Code No.11, 12 Accelerator pedal position sensor (APS)

Probable cause

If the APS output voltage (APS opening voltage) is 4.8 V or higher when the engine
is idling, the output voltage is judged to be too high and diagnosis code No. 13
is output. If the APS output voltage (APS opening voltage) is 0.335 V or lower
when the engine is idling, the output voltage is judged to be too low and diagnosis
code No. 13 is output.
If the APS output voltage (APS power supply voltage) is 3.0 V or lower or if it
is 5.7 V or higher when the engine is idling, the APS is judged to be faulty and
diagnosis code No. 14 is output.
