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- 3 4 9 , "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)

Without CONSULT-II
1. Turn ignition switch to “ON” position. (Do not start engine.)
2. Check voltage between TCM terminals 26, 27, 34, 35, 36 and
ground while moving selector lever through each position.
OK or NG
OK >> GO TO 4.
NG >> Check the following items:
●PNP switch (Refer to AT- 3 4 9 , "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)
3. CHECK OVERDRIVE CONTROL 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 “OVERDRIVE SWITCH”.
Check the signal of the overdrive control switch is indicated properly.
(Overdrive control switch “ON” displayed on CONSULT-II means
overdrive “OFF”.)
OK or NG
OK >> GO TO 5.
NG >> Check the following items:
●Overdrive control switch (Refer to AT- 3 4 9 , "COMPO-
NENT INSPECTION" .)
●Harness for short or open between TCM and over-
drive control switch
●Harness of ground circuit for overdrive control switch
