Try resetting the ECU with this procedure.

A. The Main Power Switch (located on the left side of the steering column) MUST be
in the off position (red line not showing on the switch button).
B. Place the transmission selector in park.
C. Make sure the right-side sliding door is fully closed (manual operation).
D. Disconnect the 12V negative battery terminal and wait for more than one (1)
minute, then reconnect the negative battery terminal.
E. Turn the ignition switch to the on position.
F. Push the power door Main switch on (red line on the switch will be showing)
and wait for 10 seconds.
G. Open the sliding door by pushing either the power sliding door control button
(Located on the right side of the dash by the radio or on the pillar) or the
remote switch on the key ring and allow the door to open all the way).
Wait three (3) seconds after the motor stops running before proceeding.
H. Close the sliding door by pushing either the power sliding door control button
(Located on the right side of the dash by the radio or on the pillar) or the
remote control button and let the door close all the way.
Wait three (3) seconds after the motor stops running before proceeding.
I. Repeat steps G and H.
Important:
Steps G and H, described above, must be repeated.
J. Confirm proper operation of the power sliding door system.

If the reset procedure fails, then the module needs to be replaced.
I have attached the diagrams for the door module for anyone might be looking to replace it.
Let me know of any questions.
Thank you.
