Scheme 7: Interior Light Switch Test/Replacement
Scheme 8
- Remove the moonroof switch (see «MOONROOF SWITCH TEST/REPLACEMENT»(/acura/tl/iii-2003-2006/remont/sun-rooft-topconvertible-top/#power-moonroof) ).
- Carefully pull down the roof console (A).
- Disconnect the 20P connector (B) from the roof console.
- Check for continuity between the terminals in each interior light switch position according to (Scheme 8). NOTE: Before testing, check the front individual map light bulb(s). When check for continuity across the diode, use the diode setting on the digital volt/ohm meter to check the diode bias.
- If the continuity is not as specified, replace the roof console as an assembly.
Scheme 9
Scheme 9: Front Individual Map Light Replacement
- Carefully pry off the lens (A) with a small screwdriver. Front Map Light: 4 CP x 2
- Check the bulb(s) (B). If the bulb is OK, but there is a malfunction, check the interior light switch (see «INTERIOR LIGHT SWITCH TEST/REPLACEMENT»(/acura/tl/iii-2003-2006/remont/interiorillumination-lights/#interior-lights) ).
Scheme 10
Scheme 10: Rear Map Light Replacement
- Carefully pry off the lens (A) with a small screwdriver. Rear Map Light: 5 W x 2
- Remove the two mounting bolts.
- Disconnect the 3P connector (B) from the rear map light (C).
- Install in the reverse order of removal.
Scheme 11
Scheme 11: Glove Box Light Test/Replacement
- Remove the glove box stops and damper (see «GLOVE BOX HOUSING REMOVAL/ INSTALLATION»(/acura/tl/iii-2003-2006/remont/exteriorinterior-trim/#dashboard__glove-box-housing-removal-installation) ).
- Carefully pry the glove box light out of the glove box housing.
- Twist the socket (A) to remove it from the glove box light (B). Glove Box Light: 1.4 W
- Remove the bulb (C) from the socket.
- Install in the reverse order of removal.
Scheme 12
Scheme 12: Courtesy Light Replacement
- Carefully pry off the lens (A) with a small screwdriver. Courtesy Light: 2CP
- Remove the bulb (B) from the socket.
- Install in the reverse order of removal.
Scheme 13
Scheme 13: Vanity Mirror Light Switch Test
- Remove the sunvisor (see «HEADLINER REMOVAL/INSTALLATION»(/acura/tl/iii-2003-2006/remont/exteriorinterior-trim/#interior-trim__headliner-removalinstallation) ).
- Disconnect the 2P connector (A) from the sunvisor (B).
- Check for continuity between the No. 1 and No. 2 terminals. With the vanity mirror cover (C) opened, there should be continuity. With the vanity mirror cover (C) closed, there should be no continuity.
- If the continuity check is not as specified, replace the sunvisor.
Scheme 14
Scheme 14: Vanity Mirror Light Replacement
- Wrap the tip of the screwdriver in tape.
- Carefully slide the screwdriver between the metal mounting ring (A) and the headliner until the tip of the screwdriver is resting against the lens locking tab. Vanity Mirror Light: 5 W NOTE: Right side is shown. Left side is symmetrical.
- Rotate the screwdriver handle toward the center of the vehicle while pressing the tip of the screwdriver against the locking tab to release the lens.
- Pull the lens (B) down.
- Disconnect the 2P connector (C) from the light.
- Install in the reverse order of removal.
Scheme 15
Scheme 15: Console Box Light Replacement
- Remove the center console (see «CENTER CONSOLE REAR SECTION REMOVAL/INSTALLATION»(/acura/tl/iii-2003-2006/remont/gauges-instrument-panels/#consoles__center-console-rear-section-removalinstallation) ).
- Disconnect the 2P connector (A) from the console box light. Console Box Light: 1.4 W
- Carefully pry out the console box light lens (B).
- Turn the bulb socket (C) 45° counterclockwise to remove it from the lens. NOTE: If only replacing the lens, it is not necessary to remove the center console box.
Scheme 16
Scheme 16: Ambient Light Test
- Remove the roof console and disconnect the 20P connector (see «INTERIOR LIGHT SWITCH TEST/REPLACEMENT»(/acura/tl/iii-2003-2006/remont/interiorillumination-lights/#interior-lights) ).
- Connect the roof console connector terminal No. 3 to battery power and terminal No. 7 to body ground. The ambient lights (A) should turn on. If they do not turn on, replace the roof console.
Scheme 17
Scheme 17: Trunk Light Test/Replacement
- Open the trunk lid.
- Carefully pry out the trunk light (A). Trunk Light: 5 W
- Disconnect the 2P connector (B) from the light.
- Check for continuity between the No. 1 (+) and No. 2 (-) terminals. There should be continuity. If there is no continuity, check the bulb (C). If the bulb is OK, replace the trunk light.
Scheme 18
Scheme 18: Trunk Lid Latch Switch Test
- Open the trunk lid and remove the trunk lid trim (see «TRIM REMOVAL/INSTALLATION - TRUNK LID»(/acura/tl/iii-2003-2006/remont/exteriorinterior-trim/#interior-trim__trim-removalinstallation-trunk-lid) ).
- Disconnect the 3P connector (A) from the trunk lid latch (B).
- Check for continuity between the No. 2 and No. 3 terminals. There should be continuity with the trunk lid latch unlatched (trunk lid open). There should be no continuity with the trunk lid latch latched (trunk lid closed).
- If the continuity is not as specified, replace the trunk lid latch switch.
