Toyota Corolla Repair Manual: Circuit description
The park/neutral position switch detects the shift lever position and sends signals to the ecm.
Monitor description
The park/neutral position switch detects the gearshift position and sends a signal to the ecm.
For security, the park/neutral position switch detects the gearshift position so that engine can be started only when the vehicle is in p or n shift position.
When the park/neutral position switch sends more than one signal at a time from switch positions p, r, n, 2, or l the ecm interprets this as a fault in the switch. The ecm will turn on the mil.

Source voltage drop
The srs is equipped with a voltage–increase circuit (dc–dc converter) in the
airbag sensor assy center
in case the source voltage drops.
When the battery voltage drops, the voltage–increase circuit (dc–dc converter)
functions to increase the
voltage of the srs to normal voltage.

Inspection procedure
Hint:
if dtcs p0115, p0116, p0117, p0118 and p0125 are output
simultaneously, the engine coolant temperature
sensor circuit may be open or short. Perform the troubleshooting of dtc
p0115, p0117 or
p0118 first.
