when changing selector lever from “2” to “1” position.
1.
CHECK PNP SWITCH CIRCUIT
With CONSULT-II
Does “TCM INPUT SIGNALS” in “DATA MONITOR” show damage to PNP switch circuit?
Without CONSULT-II
Does self-diagnosis show damage to PNP switch circuit?
Yes or No
Yes
>> Check PNP switch circuit. Refer to
AT-337, "21. TCM Self-diagnosis Does Not Activate (PNP &
Overdrive Control Switches, and Throttle Position Sensor Circuit Checks)"
.
No
>> GO TO 2
2.
CHECK SYMPTOM
Check again.
OK or NG
OK
>> INSPECTION END
NG
>> 1. Perform TCM input/output signal inspection.
2. If NG, recheck TCM pin terminals for damage or loose connection with harness connector.

CHECK SYMPTOM
Is 6. Vehicle Does Not Creep Backward In “R” Position OK?
Yes or No
Yes

21. TCM Self-diagnosis Does Not Activate (PNP & Overdrive Control Switches,
and Throttle Position Sensor Circuit Checks)
ECS009AR
SYMPTOM:
O/D OFF indicator lamp does not come on in TCM self-diagnostic procedure even if the lamp circuit is
good.
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

[EXC.F/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)

2.
CHECK PNP SWITCH CIRCUIT (WITHOUT CONSULT-II)
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
.)
●
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)
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
.)
●
Harness for short or open between TCM and over-
drive control switch (Main harness)
●
Harness of ground circuit for overdrive control switch
(Main harness) for short or open
