DESCRIPTION
lPNP switch
The PNP switch assembly includes a transmission position switch. The transmission position switch
detects the selector lever position and sends a signal to the TCM.
lOverdrive control switch
Detects the overdrive control switch position (ON or OFF) and sends a signal to the TCM.
lThrottle position sensor *
*: This sensor means accelerator pedal position (APP) senror.
Electric throttle control actuator consists of throttle control motor, acceleration pedal position sensor, throt-
tle position sensor, etc. The actuator sends a signal to the TCM.

PNP Switch
1. Check continuity between terminals 1 and 3 and between termi-
nals 2 and 4, 5, 6, 7, 8, 9 while moving manual shaft through
each position.
2. If NG, check again with manual control cable disconnected from
manual shaft of A/T assembly. Refer to step 1.
3. If OK on step 2, adjust manual control cable. Refer toAT-456,
"Control Cable Adjustment".
4. If NG on step 2, remove PNP switch from A/T and check conti-
nuity of PNP switch terminals. Refer to step 1.
5. If OK on step 4, adjust PNP switch. Refer toAT- 4 5 6 , "

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.
