DESCRIPTION
●

The park/neutral (PNP) switch assembly includes a transmission range switch. The transmission range
switch detects the selector lever position and sends a signal to the TCM.
●
Stop lamp switch signal
Detects the brake pedal state (stop lamp switch is ON or OFF) and sends a signal via CAN communica-
tion line to the TCM.
●

ECM judges throttle opening based on a signal from accelerator pedal position sensor, and sends the sig-
nal via CAN communication line to TCM.
