Audio Remote Switch Does Not Work Properly

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2015 Honda Crosstour, 2014 Honda Crosstour, 2013 Honda Crosstour, 2012 Honda Crosstour, and 2011 Honda Accord Crosstour. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

Check the vehicle battery condition first (see BATTERY TEST ).
Check the connectors for poor connections or loose terminals.

Turn the ignition switch to ON (II).
Turn on the audio unit and check the audio unit operation (volume up, volume down, CH (UP), CH (DOWN), MODE).
Is the audio unit operation OK?

YES -Operation is normal.

NO -Go to next step.
Go to the audio button, knob, and audio remote switch detection mode in the audio system Self-diagnostic Function (see SELF-DIAGNOSTIC FUNCTION ).
Are the audio remote switch functions detected and functioning properly?

YES -Substitute a known-good audio unit; with navigation system (see WITH NAVIGATION SYSTEM ), without navigation system (see WITHOUT NAVIGATION SYSTEM ), and recheck. If the symptom/indication goes away, replace the original audio unit; with navigation system (see WITH NAVIGATION SYSTEM ), without navigation system (see WITHOUT NAVIGATION SYSTEM ).

NO -Go to next step.
Turn the ignition switch to LOCK (0).
Do the Audio Remote Switch Test (see AUDIO REMOTE SWITCH TEST ).
Is the audio remote switch OK?

YES -Go to next step.

NO -Replace the audio remote switch (see STEERING WHEEL DISASSEMBLY/REASSEMBLY ).
Disconnect audio unit connector A (24P).
NOTE: Eject all the CDs before disconnecting the. audio unit and audio disc changer to prevent damaging the CD player's load mechanism.

Reconnect the audio remote switch, and measure the resistance between audio unit connector A (24P) terminals No. 11 and No. 22 as specified in the table.

AUDIO REMOTE SWITCH TABLE

MODEL SPECIFICATION

Button held down	VOL DOWN	VOL UP	CH (-)	CH (+)	MODE	(No button pressed)
Resistance	about 100 Ω	about 357 Ω	about 775 Ω	about 1.7 kΩ	about 3.7 kΩ	about 10 kΩ

Is the resistance OK?

YES -Go to next step.

NO -Repair a short 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 ).

Check for continuity between body ground and audio unit connector A (24P) terminals No. 11 and No. 22 individually.

Is there continuity?

YES -Repair a short to body ground 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 ).

NO -Replace the audio unit:
- With navigation system (see WITH NAVIGATION SYSTEM ).
- Without navigation system (see WITHOUT NAVIGATION SYSTEM ).
