Audio remote switch does not work properly

NOTE: Check the vehicle battery condition test.

Do the audio remote switch test.
- '04 model (see '04 MODEL )
- '05-08 models (see '05 AND '06-08 MODELS WITHOUT NAVIGATION )
Is the audio remote switch OK?

YES - Go to step 2.

NO - Replace the audio remote switch.
Remove the audio-HVAC display module (see AUDIO-HVAC DISPLAY MODULE REMOVAL/INSTALLATION ).
NOTE: Eject all the discs before removing the audio unit to prevent damaging the CD player's load mechanism.

Measure the resistance between the audio unit connector A (20P) terminal No. 3 and No. 11 as specified in the table.

TABLE

RESISTANCE REFERENCE

Button held down	VOL DOWN	VOL UP	CH(-)	CH(-B	MODE	(NONE)
Resistance	about 100 Ω	about 357 Ω	about 775 Ω	about 1.7 kΩ	about 3.7 kΩ	about 10 kΩ

Is the resistance as specified?

YES - Go to step 4.

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 ).

Check for continuity between body ground and the audio unit connector A (20P) terminal No. 3 and No. 11 individually.

Is there continuity?

YES - Repair 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 (see AUDIO-HVAC DISPLAY PANEL REMOVAL/INSTALLATION ).
