Audio System - Audio remote switch does not work properly (audio switch panel buttons work) (Without Navigation)

Audio remote switch does not work properly (audio switch panel buttons work) 

NOTE: 

• Check the vehicle battery condition first .
• Check the connectors for poor connections or loose terminals.

1. Problem verification

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

   -2. Turn on the audio unit, and using the audio remote switch buttons, check if the audio system operates properly.

   Is the audio system operation OK?

   YES 

   Intermittent failure, the system is OK at this time.

   NO 

   The failure is duplicated, go to step 2.

2. Determine possible failure area (audio remote-HFL switch, others)

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

   -2. Do the Audio Remote Switch Test .

   Is the audio remote switch OK?

   YES 

   Go to step 3.

   NO 

   Replace the audio remote-HFL switch .

3. Shorted wire check (AUDIO REMOTE SW line)

   -1. Disconnect the following connector.

   NOTE:  Eject the disc before disconnecting the audio unit to prevent damaging the CD player's load mechanism.

   Audio unit connector A (24P)

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

   Test condition	OFF mode
   	Audio remote-HFL switch 12P connector: disconnected
   	Audio unit connector A (24P): disconnected
   Test circuit	AUDIO REMOTE SW
   Test point 1	Audio unit connector A (24P) No. 22 (PNK)
   Test point 2	Body ground

   The AUDIO REMOTE SW wire is not shorted to ground. Go to step 4.

4. Open wire check (AUDIO REMOTE SW line, REMOTE SW GND line)

   -1. Reconnect the audio remote-HFL switch 12P connector , and measure the resistance between test points 1 and 2 as specified in the table.

   Test condition	OFF mode
   	Audio unit connector A (24P): disconnected
   Test circuit	AUDIO REMOTE SW, REMOTE SW GND
   Test point 1	Audio unit connector A (24P) No. 22 (PNK)
   Test point 2	Audio unit connector A (24P) No. 11 (BRN)

   Button held down	VOL DOWN	VOL UP	CH (-)	CH (+)	MODE	(No button pressed)
   Resistance	about 99 '	about 357 '	about 775 '	about 1.7 kΩ	about 3.7 kΩ	about 10 kΩ

   Is the resistance OK?

   YES 

   Replace the audio unit .

   NO 

   Repair an open in the wire(s) between the audio unit and the audio remote switch. If the wires are OK, replace the cable reel .
