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)
