21. TCM Self-diagnosis Does Not Activate (PNP,
Overdrive Control and Throttle Position
Switches Circuit Checks)
NJAT0351SYMPTOM:
O/D OFF indicator lamp does not come on in TCM self-diag-
nostic procedure even if the lamp circuit is good.
DESCRIPTIONNJAT0351S01+PNP switch
The PNP switch assembly includes a transmission range
switch. The transmission range 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.
+Throttle position switch
Consists of a wide open throttle position switch and a closed
throttle position switch.
The wide open throttle 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.

saxle operates correctly. With parking brake applied, idle
engine. Move selector lever through ªNº to ªDº, to ª2º, to ª1º and
ªRº positions. A slight shock should be felt through the hand
gripping the selector each time the transaxle is shifted.
10. Perform road test. Refer to AT-85.
