Does “TCM INPUT SIGNALS” in Data Monitor show damage to overdrive control switch circuit?

 Without CONSULT

Does self-diagnosis show damage to overdrive control switch cir-
cuit?

Yes or No

Yes

>> Check overdrive control switch circuit. Refer to 

AT-389,

"DIAGNOSTIC PROCEDURE"

 .

No

>> Go to 

AT-374, "10. A/T Does Not Shift: D

TROUBLE DIAGNOSES FOR SYMPTOMS

DESCRIPTION

●

PNP switch
The PNP switch assembly includes a transmission range switch.
The transmission range switch detects the selector 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.

●

Throttle position switch
Consists of a wide open throttle position switch and a closed
throttle position switch.
The wide open position switch sends a signal to the TCM when
the throttle valve is open at least 1/2 of the full throttle position.
The closed throttle position switch sends a signal to the TCM
when the throttle valve is fully closed.
