Audio System - Poor or no sound with XM radio (Audio-navigation unit does display XM channels) (KA models with Navigation) (2013 2014 2015)

Poor or no sound with XM radio (Audio-navigation unit does display XM channels) 

NOTE: 

• Check the vehicle battery condition first .
• Check the radio reception in an open area. Poor reception/interference can be caused by tall buildings, mountains, or high-voltage power lines are nearby.
• If you can only tune to channel 000, 001, and 174, make sure the XM radio is set to channel mode (see the Owner's Manual), if it is set to channel mode, call XM Radio client support at 800-852-9696, and check the account activation status.
• Check the connectors for poor connections or loose terminals.

1. Determine possible failure area (audio system, others)

   -1. Press the engine start/stop button to select the ON mode.

   -2. Check that the audio system is operating normally, from different audio sources (AM/FM and CD) and the speaker sound levels are normal.

   Does the audio system work normally and is the audio output from the speaker normal when playing various audio sources?

   YES 

   Go to step 2.

   NO 

   Go to No sound is heard from the speaker(s) (display is normal) (with navigation) troubleshooting .

2. Problem verification

   -1. Park the vehicle outside with a clear view of the southern horizon.

   -2. Turn on the audio system, and press the XM button.

   -3. Set the proper XM radio station.

   Does the XM radio play?

   YES 

   Intermittent failure, the system is OK at this time.

   NO 

   The failure is duplicated, go to step 3.

3. Determine possible failure area (related unit, others)

   -1. Press the engine start/stop button to select the OFF mode.

   -2. Disconnect the following connector.

   HandsFreeLink control unit 32P connector

   -3. Press the engine start/stop button to select the ON mode.

   -4. Turn on the audio system, and press the XM button.

   Does the XM radio play?

   YES 

   Replace the HandsFreeLink control unit .

   NO 

   Go to step 4.

4. Shorted wire check (GA AUDIO lines) 1

   -1. Press the engine start/stop button to select the OFF mode.

   -2. Disconnect the following connectors.

   Audio-navigation unit connector C (14P)

   AcuraLink control unit (XM receiver) connector A (32P)

   -3. Check for continuity between these test points and body ground individually.

   Test condition	OFF mode
   	HandsFreeLink control unit 32P connector: disconnected
   	Audio-navigation unit connector C (14P): disconnected
   	AcuraLink control unit (XM receiver) connector A (32P): disconnected

   Connector	Test circuit	Terminal
   Audio-navigation unit connector C (14P)	GA AUDIO L+	No. 1 (RED)
   	GA AUDIO R+	No. 2 (WHT)
   	GA AUDIO L	No. 7 (GRN)
   	GA AUDIO R	No. 8 (BLK)

   Is there continuity?

   YES 

   There is a short to body ground in the wire(s) between the audio-navigation unit and the AcuraLink control unit (XM receiver). Replace the affected shielded harness.

   NO 

   The GA AUDIO wires are not shorted to ground. Go to step 5.

5. Shorted wire check (GA AUDIO lines) 2

   -1. Check for continuity between test points 1 and 2.

   Test condition	OFF mode
   	HandsFreeLink control unit 32P connector: disconnected
   	Audio-navigation unit connector C (14P): disconnected
   	AcuraLink control unit (XM receiver) connector A (32P): disconnected

   Test circuits	Connector: Audio-navigation unit connector C (14P)
   	Test point 1	Test points 2
   GA AUDIO L+ to GA AUDIO R+, SH GA AUDIO, GA AUDIO L-, GA AUDIO R-	No. 1 (RED)	No. 2 (WHT), No. 3 (GRY), No. 7 (GRN), No. 8 (BLK)
   GA AUDIO R+ to SH GA AUDIO, GA AUDIO L-, GA AUDIO R-	No. 2 (WHT)	No. 3 (GRY), No. 7 (GRN), No. 8 (BLK)
   SH GA AUDIO to GA AUDIO L-, GA AUDIO R-	No. 3 (GRY)	No. 7 (GRN), No. 8 (BLK)
   GA AUDIO L-to GA AUDIO R-	No. 7 (GRN)	No. 8 (BLK)

   Is there continuity between any of the terminals?

   YES 

   There is a short in the wires between the audio-navigation unit and the AcuraLink control unit (XM receiver). Replace the affected shielded harness.

   NO 

   The GA AUDIO wires are not shorted in the wires. Go to step 6.

6. Open wire check (GA AUDIO lines)

   -1. Check for continuity between test points 1 and 2.

   Test condition	OFF mode
   	HandsFreeLink control unit 32P connector: disconnected
   	Audio-navigation unit connector C (14P): disconnected
   	AcuraLink control unit (XM receiver) connector A (32P): disconnected

   Test circuit	Test point 1:Audio-navigation unit connector C (14P)	Test point 2:AcuraLink control unit (XM receiver) connector A (32P)
   GA AUDIO L+	No. 1 (RED)	No. 2 (RED)
   GA AUDIO R+	No. 2 (WHT)	No. 4 (WHT)
   GA AUDIO L	No. 7 (GRN)	No. 1 (GRN)
   GA AUDIO R	No. 8 (BLK)	No. 3 (BLK)
