ELECTRONIC SHIFT LEVER SYSTEM, Diagnostic DTC:P272D19

DTC Code DTC Name
P272D19 Park Pawl Motor Power Supply System Circuit Current Above Threshold

DESCRIPTION

The shift control actuator assembly consists of a parking lock motor and rotation angle sensor.

The hybrid vehicle control ECU receives a P position switch signal from the P position switch (transmission shift main switch) and operates the parking lock motor through current control to engage and release the parking lock.

If the hybrid vehicle control ECU detects a malfunction in the parking lock motor system and/or ground circuit, it stores this DTC.

      Measure the resistance according to the value(s) in the table below.

      Standard Resistance (Check for Open)
      Tester Connection Condition Specified Condition
      I3-3 (E1) - Body ground Power switch off Below 1 Ω
      I2-34 (E12) - Body ground Power switch off Below 1 Ω
      I2-12 (E01) - Body ground Power switch off Below 1 Ω
      I2-11 (E02) - Body ground Power switch off Below 1 Ω
      I2-10 (E03) - Body ground Power switch off Below 1 Ω
    3. Reconnect the I2 and I3 hybrid vehicle control ECU connectors.
