ELECTRONIC SHIFT LEVER SYSTEM, Diagnostic DTC:P272C00

DTC Code DTC Name
P272C00 Park Pawl Motor Driving Time Too Long

DESCRIPTION

The shift control ECU receives shift lever position signals from the shift lever position sensor (transmission floor shift assembly) and P position switch signal from the P position switch (shift position indicator) to operates the shift control actuator assembly and detect the time for switching the shift state between park (P) (parking lock engaged) and other than park (P) (parking lock released). When the shift control ECU detects a malfunction at this time, the DTC is stored in the ECM.
