Roof Console Input Test/Replacement

WARNING: This page is about a different car, the 2013 Acura MDX, 2012 Acura MDX, 2011 Acura MDX, and 2010 Acura MDX. However, it is still accessible from the selected car via links, so may be relevant.

Turn the map light switch OFF.
Open the sunglass holder, then remove the two screws (A).

Carefully pull on the roof console (B) to disengage the two clips (C) from the roof.
Disconnect the 20P connector (D) from the roof console.
Inspect the connector and socket terminals to be sure they are all making good contact.
- If the terminals are bent, loose, or corroded, repair them as necessary, and recheck the system.
- If the terminals look OK, go to step 6.

With the connector still disconnected, do the following input tests:

If any test indicates a problem, find and correct the cause, then recheck the system.
If all the input tests prove OK, go to step 7.

Cavity	Wire	Test condition	Test: Desired result	Possible cause if desired result is not obtained
5	LT GRN	Disconnect under-dash fuse/relay box connector X (39P)	Check for continuity between terminal No. 5 and under-dash fuse/relay box connector X (39P) terminal No. 9: There should be continuity.	An open or high resistance in the wire
6	ORN	Disconnect Driver's under-dash fuse/relay box connector Q(14P)	Check for continuity between terminal No. 6 and Driver's under-dash fuse/relay box connector Q (14P) terminal No. 11: There should be continuity.	An open or high resistance in the wire
8	GRN	Disconnect the rear individual map lights 10P connector	Check for continuity between terminal No. 8 and rear individual map lights 10P connector terminal No. 8: There should be continuity.	An open or high resistance in the wire
9	YEL	Disconnect the rear individual map lights 10P connector	Check for continuity between terminal No. 9 and rear individual map lights 10P connector terminal No. 9: There should be continuity.	An open or high resistance in the wire
2	RED	Disconnect the gauge control module connector B (24P)	Check for continuity between terminal No. 2 and gauge control module connector B (24P) terminal No. 2: There should be continuity.	An open or high resistance in the wire

Reconnect the connector to the roof console, and do the following input tests:

If any test indicates a problem, find and correct the cause, then recheck the system.
If all the input tests prove OK, the roof console must be faulty; replace it.

Cavity	Wire	Test condition	Test: Desired result	Possible cause if desired result is not obtained
4	BLK	In all ignition switch positions	Measure the voltage to ground: There should be less than 0.2 V.	Poor ground (G601) or an open in the ground wire Faulty under-dash fuse/relay box An open or high resistance in the wire
3	WHT	Under all conditions	Measure the voltage to ground: There should be battery voltage.	Blown No. 6 (7.5 A) fuse in the under-dash fuse/relay box Faulty under-dash fuse/relay box An open or high resistance in the wire
1	LT BLU	Combination light switch (PARKING LIGHT position) ON	Measure the voltage to ground: There should be battery voltage.	Blown No. 22 (7.5 A) fuse in the under-hood fuse/relay box Faulty under-hood fuse/relay box Faulty interior light relay An open or high resistance in the wire
