AUTOMATIC TRANSMISSION (4 A / T) 7B1-17
AUTOMATIC TRANSMISSION DIAGNOSIS
This vehicle is equipped with an electronic transmission control system, which control the automatic shift up and
shift down timing, TCC operation, etc. suitably to vehicle driving conditions.
PCM (ECM) has an On-Board Diagnosis system which detects a malfunction in this system and abnormality of
those parts that influence the engine exhaust emission.
When diagnosing a trouble in transmission including this system, be sure to have full understanding of the outline
of ªOn-board Diagnostic Systemº and each item in ªPrecaution in Diagnosing Troubleº and execute diagnosis ac-
cording to ªAUTOMATIC TRANSMISSION DIAGNOSTIC FLOW TABLEº given below to obtain correct result
smoothly.
NOTE:
There are two types of ON-BOARD DIAGNOSTIC SYSTEM de-
pending on vehicle specifications. The type of system for ve-
hicle being serviced can be identified by whether equipped
with monitor connector or not.

7B1-54 AUTOMATIC TRANSMISSION (4 A / T)
LINE PRESSURE TEST
Purpose of this test is to check operating conditions of each part by
measuring fluid pressure in fluid pressure line. Line pressure test
requires following conditions.

Automatic fluid is at normal operating temperature (70 to 80C /
158 ± 176F).

Fluid is filled to proper level (between FULL HOT and LOW HOT
on dipstick).
1) Apply parking brake securely and place checks against wheels.
2) Attach oil pressure gauge to fluid pressure check hole in trans-
mission case.
Special Tool
(A): 09925-37810
CAUTION:
After attaching oil pressure gauge, check that not fluid
leakage exists.
3) Depress foot brake fully, run engine at idle and stall and then
check fluid pressure in ªDº or ªRº range.
CAUTION:
Do not continue running engine at stall speed longer than
5 seconds.
