Here is the original PDF, which I am "quoting" from

 

That's right and I posted it. The reason these are meant for MAZDA TRAINED MECNAIC or others that have some experience and certification in th auto mechanic service industry are because they look at all the TSB including the previous ones! You are not a trained mechanic, and this TSB was not meant for you> But I understand the mentality to post them!

One reason many TSBs are updated (superseded) are because another likely and hopefully (but no guarantee) an individual relooked at the original TSB determined it necessary to update the information. In this case I can see why. IMHO Mazda was spending too much money on a service that really was not needed nor was it categorically and issue with the HLA's and IMHO should not have been written up as a TSB in the first place. If any Automotive Engineers understands how HLAs designed, their operation and then manufactured ad to that the random changes of a few being manufactured out of specification on a wide range of supposed effected engines that they state as year model and VIN instead of block number, let alone a complete of HLA in one engine or even a few is statistically so high I wouldn't even know how to get the base number to estimate.


READ THIS it is on every page of every TSB from MAZDA!!!!





I am posting 2 of the same pictures to support what I said about who is suppose to use a Mazda TSB . The TSB you provided the number for it has 2 pages. LOL

 

 

Don't take it personally.. I scrutinize TSB on several platforms from dealers that submit them to corporate service operations. They use to be spot on and then like everything else in the world things changed and almost any person in a service department can write and submit them for publication.
On this forum you can choose whom you want to get the best service information from as well other things Mazda related. I am by far no expert on everything and there are more threads I don't participate because either I just don't want to spend the time or I feel I personally have not had enough acquired service experience to post absolute service advice. Example ....I may be L2 certified but diesels sound and smell funny so I tend to avoid working on them unless pressed.

 

Despite the ramblings and typos from the other guy, you can post, use, reference, quote any TSB you want. In the USA all manufacturer communications are legally required to be provided to the NHTSA and then posted online for public use. They must provide them to the NHTSA within 30 days of distribution to dealers. They have no choice. Despite whatever notices or clarifiers a manufacturer adds to the bulletins, they are not applicable. They have no rights to it. You don't need to be a tech to read them and understand. The problem is often lack of tools or experience. Being a DIY doesn't mean you are automatically less knowledgeable or experienced than a technician that has passed a few ASE multiple choice tests. Most licensed techs are more knowledgeable and experienced than your average DIY. It just doesn't mean it's automatic. Some licensed techs are awful. Many DIY have no idea what they are doing. It's a case by case thing.

 

 

April Update.

Today, I installed Foglight on my 2018 CX-5 Sport.

 

Short Review of Foglight:
* I can confirm that foglight wires are "pre-wired" from factory (almost plug & play, saving a good amount of installation time)
* You can purchase OEM fogs, which are kinda expensive but have better output. I personally went with Amazon one ($55), which is only for "looks." (You can upgrade later)
* You don't have to remove the front bumper; I installed it from underneath (while having the front of the car on a ramp).
* You need to purchase a new light switch which has a "foglight' function. (readily available on eBay)

Good weekend project!!
