With CONSULT-II
Does “TCM INPUT SIGNALS” in “DATA MONITOR” show damage to PNP switch circuit?
Without CONSULT-II
Does self-diagnosis show damage to PNP switch circuit?
Ye s o r N o
Yes >> Check PNP switch circuit. Refer to “21. TCM Self-diag-
nosis Does Not Activate (PNP & Overdrive Control
switches, and Throttle Position Sensor Circuit Checks)”,
AT-260, "
21. TCM Self-diagnosis Does Not Activate

CONSULT-IIECS004NW
After performing “SELF-DIAGNOSTIC PROCEDURE (WITH CONSULT-II)” (AT - 2 7 3 , "Diagnostic Procedure
Without CONSULT-II"), place check marks for results on the “DIAGNOSTIC WORKSHEET”,AT-280, "DIAG-
NOSTIC 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 toAT - 3 4 7 , "
TCM Terminals and Reference Value".If
result is NG, refer toPG-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.

REMOVAL AND INSTALLATION
3. Install torque converter to drive plate.
lWith converter installed, rotate crankshaft several turns
to check that transaxle rotates freely without binding.
4. Tighten belts fixing transaxle.
5. Reinstall any part removed.
6. Adjust control cable. Refer toAT-456, "
Control Cable Adjust-
ment".
7. Check continuity of PNP switch. Refer toAT-130, "
DTC P0705
PARK/NEUTRAL POSITION (PNP) SWITCH".
8. Refill transaxle with ATF and check fluid level.
9. Move selector lever through all positions to be sure that tran-
saxle operates correctly. With parking brake applied, idle
engine. Move selector lever through “N” to “D”, to “2”, to “1” and
“R” positions. A slight shock should be felt through the hand
gripping the selector each time the transaxle is shifted.
10. Perform road test. Refer toAT-69, "
