TROUBLE DIAGNOSES FOR SYMPTOMS
DESCRIPTION
●PNP 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.
●Overdrive control switch
Detects the overdrive control switch position (ON or OFF) and
sends a signal to the TCM.
●Closed throttle position signal and wide-open throttle position
signal
ECM judges throttle opening based on a signal from accelerator
pedal position sensor, and sends the signal via CAN communi-
cation to TCM.
DIAGNOSTIC PROCEDURE
1. CHECK PNP SWITCH CIRCUIT (WITH CONSULT-II)
With CONSULT-II
1. Turn ignition switch to “ON” position.
(Do not start engine.)
2. Select “TCM INPUT SIGNALS” in “DATA MONITOR” mode for “A/T” with CONSULT-II.
3. Read out “P/N”, “R”, “D”, “2” and “1” position switches moving selector lever to each position.
Check that the signal of the selector lever position is indicated
properly.
OK or NG
OK >> GO TO 3.
NG >> Check the following items:
●PNP switch (Refer to AT- 2 4 6 , "COMPONENT
INSPECTION" .)
●Harness for short or open between ignition switch and
PNP switch
●Harness for short or open between PNP switch and
TCM
●Diode (P, N positions)

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.
