Q: Open Door Indicator/DRIVE indicator on 2007 Honda Accord

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
On my '07 Accord, the Open Door Monitor indicates that the Passengor door on drivers side is open even when this is not the case. Also the D indicator for the Drive gear is always blinking even when another gear is selected e.g Reverse. What could be responsible for this and how do I resolve it.

Many thanks.

The open door indicator could be something that has to do with the door switch. That could be the switch, the wires to the multiplex unit or the multiplex unit itself.
The second issue is the flashing D light. This is an indication that there is a problem with the transmission. The problem could be electronic or mechanical. A code should have been stored when the light started to flash. If the code is stored it should be retrieved and a diagnosis can continue from there.
