DTC DETECTION LOGIC
DTCM.U.T.-III SE screen terms
(Trouble diagnosis content)
DTC detection condition
P272A00T/M RANGE SELECT MOTOR
(Transmission Range Select Motor Control Circuit)
1Diagnosis condition
  • When Ignition switch is ON
  • When shift actuator does not operate
Signal (terminal)Motor A (U phase / V phase / W phase) signal
ThresholdThe voltage of any one of the phase is low even though all phases of the motor coil is not energized.
noteEnergized: Approx. 0 V, Non-energized: 9 – 16 V
Diagnosis delay time—
2Diagnosis conditionAfter turning the ignition switch OFF. (During diagnosis rotation)
noteDiagnosis rotation: Turn the shift actuator relay A and B circuit OFF one by one, and partially rotate the motor for diagnosis purpose.
Signal (terminal)Motor A (U phase / V phase / W phase) signal
ThresholdThe voltage of de-energized phase is low during diagnosis rotation.
noteEnergized: Approx. 0 V, Non-energized: 9 – 16 V
Diagnosis delay time—
 
 
POSSIBLE CAUSE
  • Harness or connectors
    • Shift actuator relay A circuit is open.
    • Shift actuator motor A (U phase / V phase / W phase) circuit is open.
  • Shift actuator relay A (OFF stuck or internal disconnection)
  • Motor coil A (shift actuator)
  • Electric shift control module
 
 
FAIL-SAFE
Malfunction 1
  • No impact to vehicle behavior
Malfunction 2
  • Shifting operation is prohibited
  • Powertrain becomes neutral
noteWhen either motor A circuit or motor B circuit is judged as malfunction, only disconnecting the malfunctioning motor circuit enables to shift the gears.
 
 
DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
If “DTC CONFIRMATION PROCEDURE” has been previously conducted, always ignition switch OFF and wait at least 60 seconds before conducting the next test.

2.PERFORM DTC CONFIRMATION PROCEDURE
  1. The ignition switch is ON and wait for 2 seconds or more.
  2. The ignition switch is OFF and wait for 3 seconds or more.
  3. The ignition switch is ON and wait for 1 seconds or more.
  4. Check DTC.
