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.

20. Vehicle Does Not Decelerate By Engine Brake
AT-334

DescriptionNJAT0102+The mechanical key interlock mechanism also operates as a shift lock:
With the key switch turned to ON, the selector lever cannot be shifted from ªPº (parking) to any other
position unless the brake pedal is depressed.
With the key removed, the selector lever cannot be shifted from ªPº to any other position.
The key cannot be removed unless the selector lever is placed in ªPº.
+The shift lock and key interlock mechanisms are controlled by the ON-OFF operation of the shift lock
solenoid and by the operation of the rotator and slider located inside the key cylinder.
