I was just browsing through the May Acura ServiceNews and found this item, which has been of interest in the recent past to those of us with defective door handles:

Keyless Access Won’t Unlock the Doors or Start the Engine

Currently Applies To: ’05–08 RL

A bad front door outer handle can cause any of these
keyless access system-related problems:
• The doors won’t unlock when you reach behind
the front door outer handle.
• The ignition knob won’t turn when you go to start
the engine, making it necessary to use the key in
the remote.
• The No. 7 (10 A) fuse in the driver’s under-dash
fuse/relay box repeatedly blows (’05–06 models).
• The front door outer handle gets warm to the
touch (’05–06 models).
• The indicator needles in the gauge control
module won’t go back to their minimum values
when your turn the ignition switch to LOCK (0).
• One or more of these DTCs are set. Although you
can clear them, they come right back when you
cycle the ignition switch:
• B1055 (relay control module lost
communication with MICU [MICU message])
• B1056 (relay control module lost
communication with MICU [ALARM message])
• B1061 (relay control module lost
communication with gauge control module
[A/T message])
• B1063 (relay control module lost
communication with combination switch control
unit {WIPSW message])
• B1605 (keyless access control unit lost
communication with MICU [MICU message])
• B1610 (keyless access control unit lost
communication with gauge control module
[VSP/NE message])
• B1613 (keyless access control unit lost
communication with driver’s MPCS unit
[DOORSW message])
• B1614 (keyless access control unit lost
communication with driver’s MPCS unit
[DRLOCKSW message])
• B1615 (keyless access control unit lost
communication with driver’s MPCS unit
[ASLOCKSW message])
To make things right, here’s what you need to do:
1. Unplug the connectors from the front door outer
handles (both driver’s and passenger’s), and
replace the No. 7 fuse with a fresh one.
2. Plug in the connectors for each door handle one
at a time until the No. 7 fuse blows. Note which
handle blows the fuse, and replace that handle.
Refer to pages 20-12 thru 20-14 of the ’05–08 RL
S/M. (Online, enter keywords DOOR HANDLE
and select Front Door Outer Handle
Replacement from the list.)
3. Replace the blown No. 7 fuse, and retest.
