3 (O/D OFF).
2. Does A/T shift from D
3 (O/D OFF) to 22 ?
Read gear position.
Ye s o r N o
Yes >> GO TO 4
No >> Mark the box of “A/T Does Not Shift: D

SHEET. Continue Road Test.
5. CHECK SHIFT DOWN
1. Move selector lever from “2” to “1” position while driving in 2
2 .
2. Does A/T shift from 2
2 to 11 position?
Read gear position.
Ye s o r N o
Yes >> GO TO 6

SYMPTOM:
●Engine speed does not smoothly return to idle when A/T shifts from D4 to D3 .
●Vehicle does not decelerate by engine brake when turning overdrive control switch OFF.
●Vehicle does not decelerate by engine brake when shifting A/T from “D” to “2” position.
1.CHECK SELF-DIAGNOSTIC RESULTS
Does self-diagnosis show damage to overrun clutch solenoid valve
circuit after cruise test?
Ye s o r N O
Yes >> Check overrun clutch solenoid valve circuit. Refer to AT-
185, "DTC P1760 OVERRUN CLUTCH SOLENOID
VA LV E" (Euro-OBD).
No >> GO TO 2.
2.CHECK ACCELERATOR PEDAL POSITION (APP) SENSOR
Check accelerator pedal position (APP) sensor. Refer to AT- 1 8 0 ,
"DTC P1705 ACCELERATOR PEDAL POSITION (APP) SENSOR"
— Euro-OBD
OK or NG
OK >> GO TO 3.
NG >> Repair or replace accelerator pedal position (APP) sen-
sor. (AT- 1 8 0 , "

3.CHECK A/T FLUID CONDITION
1. Remove oil pan.
2. Check A/T fluid condition.

CONSULT-IIECS004NW
After performing AT- 2 4 7 , "SELF-DIAGNOSTIC PROCEDURE (WITH CONSULT-II)" , place check marks for
results on the AT-259, "
DIAGNOSTIC WORKSHEET" . Reference pages are provided following the items.
NOTICE:
1. The CONSULT-II electrically displays shift timing and lock-up timing (that is, operation timing of each sole-
noid).
Check for time difference between actual shift timing and the CONSULT-II display. If the difference is
noticeable, mechanical parts (except solenoids, sensors, etc.) may be malfunctioning. Check mechanical
parts using applicable diagnostic procedures.
2. Shift schedule (which implies gear position) displayed on CONSULT-II and that indicated in Service Man-
ual may differ slightly. This occurs because of the following reasons:
–Actual shift schedule has more or less tolerance or allowance,
–Shift schedule indicated in Service Manual refers to the point where shifts start, and
–Gear position displayed on CONSULT-II indicates the point where shifts are completed.
3. Shift solenoid valve “A” or “B” is displayed on CONSULT-II at the start of shifting. Gear position is dis-
played upon completion of shifting (which is computed by TCM).
4. Additional CONSULT-II information can be found in the Operation Manual supplied with the CONSULT-II
unit.
SELF-DIAGNOSTIC PROCEDURE (WITH CONSULT-II)
1. Turn on CONSULT-II and touch “A/T” for TCM self-diagnosis.
If A/T is not displayed, check TCM power supply and ground cir-
cuit. Refer to AT- 3 0 6 , "
TCM Terminals and Reference Value" . If
result is NG, refer to PG-2, "
POWER SUPPLY ROUTING" .
2. Touch “SELF-DIAG RESULTS”.
Display shows malfunction experienced since the last erasing
operation.
CONSULT-II performs “REAL TIME DIAG”.
Also, any malfunction detected while in this mode will be dis-
played at real time.
