Phase Test
WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2014 Honda Ridgeline, 2013 Honda Ridgeline, 2012 Honda Ridgeline, 2011 Honda Ridgeline, and 2010 Honda Ridgeline. However, it is still accessible from the selected car via links, so may be relevant.
Do this test to confirm proper speaker phasing.
- Insert audio diagnostic CD (T/N: 07AAZ-SDBA100) into the CD player.
- Play track No. 2 (phase) at a normal, or slightly higher than normal, volume level.
- The voice should sound centered and focused when it is in-phase.
- The voice should sound diffused, and have less bass when it is out of phase.
- If the voice changes from in-phase to out of phase as indicated by the prompt, the phasing is correct. Go to electrical noise test (see PHASE TEST ).
- If the voice always sounds out of phase, phasing is not correct. Check for
- Crossed speaker wires
- Faulty audio unit
