DTC CONFIRMATION PROCEDURE
CAUTION:
1.PREPARATION BEFORE WORK
If another "DTC CONFIRMATION PROCEDURE" occurs just before, turn ignition switch OFF and wait for at least 10 seconds, then perform the next test.
>> GO TO 2.
2.CHECK DTC DETECTION
Selector lever : "L" POSITION
Accelerator pedal position : 0.7/8 or more
Vehicle speed : 10 km/h (6 MPH) or more
Is "P285A" detected?

P073E Unable to engage r range
Description
This malfunction is detected when the A/T does not shift into reverse
position as instructed by TCM. This is not
only caused by electrical malfunction (circuits open or shorted) but by
mechanical malfunction such as control
valve sticking, improper solenoid valve operation, etc
