WARNING: This page is about a different car, the 2008 Acura CSX, 2007 Acura CSX, and 2006 Acura CSX. However, it is still accessible from the selected car via links, so may be relevant.
  1. Test the audio remote switch (see AUDIO REMOTE SWITCH TEST  ).

    Is the audio remote switch OK? 

    YES  -Go to step 2.

    NO  -Replace the audio remote switch.

  2. Check the audio system operation (volume up, volume down, CH (), CH (|), MODE).

    Is the audio unit operation OK? 

    YES  -

    • With navigation: Go to step 3.
    • Without navigation: Go to step  6.

    NO  -

  3. Remove the navigation unit (see NAVIGATION UNIT REMOVAL/INSTALLATION ).
  4. Measure the resistance between navigation unit connector B (22P) No. 6 and No. 7 terminals as specified in the table.

    AUDIO REMOTE SWITCH RESISTANCE SPECIFICATION

    Button held down VOL DOWN VOL UP CH () CH (|) MODE (NONE)
    Resistance about 100 Ω about 370 Ω about 840 Ω about 2.0 KΩ about 6.0 KΩ 10 kΩ

    Is the resistance OK? 

    YES  -Go to step 5.

    NO  -Repair open or high resistance in the circuit between the navigation unit and the audio remote switch. If the wires are OK, replace the cable reel (see CABLE REEL REPLACEMENT ).

  5. Check for continuity between the No. 6 and No. 7 terminals of navigation unit connector B (22P) and body ground.

    Is there continuity? 

    YES  -Repair short to body ground in the circuit between the navigation unit and the audio remote switch. If the wires are OK, replace the cable reel (see CABLE REEL REPLACEMENT ).

    NO  -Replace the navigation unit (see NAVIGATION UNIT REMOVAL/INSTALLATION ).

  6. Remove the audio unit (see AUDIO UNIT REMOVAL/INSTALLATION  ).
  7. Measure the resistance between audio unit connector B (20P) No. 6 and No. 7 terminals as specified in the table.

    Button held down VOL DOWN VOL UP CH () CH (|) MODE (NONE)
    Resistance about 100 Ω about 370 Ω about 840 Ω about 2.0 KΩ about 6.0 KΩ 10 kΩ

    Is the resistance OK? 

    YES  -Go to step 8.

    NO  -Repair open or high resistance in the circuit between the audio unit and the audio remote switch. If the wires are OK, replace the cable reel (see CABLE REEL REPLACEMENT ).

  8. Check for continuity between the No. 6 and No. 7 terminals of the audio unit connector B (20P) and body ground.

    Is there continuity? 

    YES  -Repair short to body ground in the circuit between audio unit and the audio remote switch. If the wires are OK, replace the cable reel (see CABLE REEL REPLACEMENT ).

    NO  -Replace the audio unit (see AUDIO UNIT REMOVAL/INSTALLATION  ).
