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.
