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
SCIA0752E
MCIA0103E
MCIA0096E
AT-240
[EURO-OBD]
TROUBLE DIAGNOSES FOR SYMPTOMS
Detects the overdrive control switch position (ON or OFF) and sends a signal to the TCM.
●
Throttle position sensor*
*: This sensor means accelerator pedal position (APP) sensor.
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.
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
.)
●
Harness for short or open between ignition switch and
PNP switch (Main harness)
●
Harness for short or open between PNP switch and
TCM (Main harness)
●
Diode (P, N positions)
