DTC P1780
CIRCUIT DESCRIPTION
The park/neutral position switch detects the shift lever position and sends signals to the ECM.
The ECM receives signals (NSW, R, 2 and L) from the park/neutral position switch. When the signal is not
sent to the ECM from the park/neutral position switch, the ECM judges that the shift lever is in D position.
DTC No.
When driving under conditions (a) and (b) for 30 seconds or
more, the park/neutral position switch is ON (N position).
