DOUBLE POSTING

Hi, I'd like to bump this conversation, as I am about to do my install myself and I'd like to ask for tips/tricks on removing the a-pillar since I definitely do not want to damage the side airbag. Do I go at it from the top portion of the trim and start prying? Also can someone please clairfy if I am removing the bolt to disconnect the battery cable? How is this different than removing the negative terminal from the post?

Everything else seems quite explanatory, I guess but any other tips/tricks would help as well.

one thread is enough, no need to post in more than one

There is a proper procedure for attaching the negative clamp to the battery to prevent damage to the battery sensor. the factory service manuals were updated after problems with that, and there was even a technical service bulletin issued about it.


TSB 07-171-20 Battery Sensor Removal and Installation Precautions

INTRODUCTION:

This Service Information Bulletin is in response to several battery sensor replacements resulting from
improper removal and / or installation practices. Some common mistakes related to battery sensor
removal and / or installation are:

• Removing the sensor from the battery post instead of removing the ground cable from the
sensor
• Not fully cleaning and de-greasing the battery post and the sensor’s ground cable connection
point before reinstalling the sensor
• Not properly supporting and holding the sensor in place with one hand while removing or
installing it or the battery ground cable
• Twisting the sensor when installing onto the battery post instead of pushing it straight down
• Over-torqueing the 10 mm hex nut on the battery post clamp portion of the sensor. This
happens when the sensor is not fully installed onto the battery post. Over-torqueing the nut
can distort and damage the sensor.
• The threaded end of the clamp bolt is crimped. If the 10 mm nut is loosened too far, the
threads of both the nut and bolt can become damaged and the clamp portion distorted.​

Wouldn't necessarily call it "easy" on a Gen 5 if that sensor is so prone to damage and other installation problems. Interesting trick, never heard of that one. Guess removing just the ground cable still allows power to some circuits?

I think the parallel wire is only a power circuit for the battery sensor itself... don’t think it provides any other electrical grounds (although I haven’t looked it up in the schematics.. this was just from reading about the redesigned battery monitoring system for the Gen5)

I don't think anyone answered my question: am I only removing the highlighted bolt to disconnect the battery cable and not removing the entire negative terminal from the battery post?

there are some good instructions in the PDF. With pictures and torque specs.
