A Technical Service Bulletin...With Sound and Video!

A tech in our shop was recently working on a 2006 Honda Accord V-6 that was making a strange noise while running...

Diagnosing noises is one area I personally dislike.  Noises can travel, occur only under certain conditions, and can be a pain to isolate.  However, with experience, finding these noises can become easier.  There are some routine failures that all result in a similar noise.  Valve train noise, for instance, is different from a rod noise.  Accessory bearing noises sound different than vacuum leaks do.  CV axles make a sound of their own, and they are not the same as a failed wheel bearing.

The problem for  younger techs is gaining the experience. 

Anyway, taking a long way around to the heart of this blog, the tech had never heard this particular sound before.  Being the thorough guy that he is, he checked for TSBs and found one:  Honda TSB 08-045, "Chirp From the Timing Belt Area".  The TSB details the fault, and includes something I've never seen before...an attached media file that shows the affected part AND the sound that it makes!

I'm attaching the link to this blog, hoping it will work for you.  If it does, scroll down the first page of the TSB and notice the picture on the bottom right.  Click on it, and it should open the media file for you.  If not, you'll have to see it online through Identifix or directly at the Honda service site.  The Honda service site is:

I don't know if this is the only TSB Honda has included this feature on, or if it is something they are routinely adding.  Either way, thanks Honda!  It does make life easier. 

I'm hoping the .pdf file below will work for you if the links do not.
