Still on the hunt for my minor battery drain issue, the module has to be on 24X7 right? never gonna use the service, but i need to be sure yanking it wont cause any other complications ( like a unsatisfied BCM input )

Bump

I would like to know this as well, if you removed any major component of the Onstar would the car still fully function correctly.

This would depend on the year of the vehicle and the version of Onstar it has

Older vehicles had a Onstar hardware unit so was a stand alone that then connected to the vehicles
on-board network like other controllers the vehicle has.

Pulling a fuse that was labeled for Onstar would not effect any other controller

In newer vehicles rolled Onstar hardware into a central unit that also had like the GPS and radio
Called "Infotainment" in this case pulling a fuse then could also remove power to those other functions

Onstar designs of todays new models the role of Onstar functions has been expanded and might in pulling a fuse effect those functions

For test purposes you could pull the fuse and if any issue you would see it right away

As a former Onstar salesperson, 2011 Onstar units are the later "integral", not to be messed with on a Cadillac.

Not to sound nefarious but coming from a privacy standpoint I would like to know how to disable the “OnStar” tracking device 🤔 seems to me they could listen to whatever or tag you wherever for whatever reason. What’s to stop them from logging data continuously without user’s knowledge? A large colamarate would never do such a thing...

thanks for the valueable feedback so far

On older Onstar designs some people simply disconnected the antenna for it
where others removed the fuse also

Others want the Onstar unit out of the vehicle so being it is connected to the vehicles on-board network
if taking the unit out that opens up the network path and and now none of the controllers can connect or exchange information on the network so to take it out the network wires that went to Onstar unit need to be looped back to close the network path and fully functional again

Example if older Onstar design then it has it's own fused circuit

Some Onstar units wired as such
595027

That’s a lot of loop back connections but doable.

Is that a generic typical Onstar setup?

Thanks for that info

Components most likely to cause a parasitic draw on the 12V battery on GM models include switches, relays, LIN buses and control modules.
A new voltage drop test in Service Information (SI) can help in determining which component may be causing a parasitic draw.

If there is an excessive load on the electrical system that is draining the battery after the ignition is turned off, review the Battery Electrical Drain/Parasitic Load Test document under 12V Charging and Starting > Diagnostic Information and Procedures in the Service Information.

It features updated information on diagnostic aids, system verification and testing, including a new parasitic draw voltage drop test and a battery draw verification sheet to help with diagnosis.

Several tables have been added in SI that list the milliAmps (mA) value across the fuses in a fuse block.
Use a DMM set to mV scale to check the voltage drop between the battery positive post and each leg of the battery junction block (if equipped) to determine which fuse block contains the draw.

Once the fuse block feed with the highest draw has been identified, go to that fuse block and check voltage drop across fuses, excluding J-case type fuses, one at a time. For three-bladed fuses, the center of the fuse is the supply voltage for both sides of the fuse.

Compare the reading to the corresponding fuse in the table. If voltage drop is found, refer to the Power Distribution Schematics to diagnose exactly which circuit of a suspected system is causing the high parasitic drain.

Testing Set Up

To begin diagnosis of a parasitic draw, it’s important to properly set up the test.
There are many things that can prevent the vehicle from completely going to sleep and passing the parasitic draw test.

1. Road test the vehicle and operate all accessories to check for proper operation.
2. Connect a 50 Amp inductive amp clamp to the negative battery cable that can read down to 1 mA.
3. With the ignition Off, open all doors, hood, trunk/liftgate (to gain access to all components and fuse blocks) and manually close all latches and switches.
4. Lock the vehicle with the key fob and move the fob a safe distance so it doesn’t wake up the vehicle (distance depends on approach detection of the vehicle).
5. With all modules and components asleep, monitor the amperage. After approximately 10 minutes, amperage should drop to a stable value less than 20 mA.
• If amperage is 40mA or higher, follow the fuse voltage drop test to identify the fuse(s) with an ongoing draw.
• Measure all fuses and record voltage drop, fuse location, type and rating.
6. After all fuses are tested, identify the suspect circuits and calculate the amperage for each.

If there are multiple control modules drawing amperage, work from the least complex component to the most. For example, for a drain on the Memory Seat Module, Body Control Module and Gateway Module, remove power to the Memory Seat Module first and verify if the other modules go to sleep properly.
In many cases, a “satellite” module like the Memory Seat Module is the most likely to cause a system to wake up.

Battery Draw Customer Verification Worksheet

The new Customer Concern Verification Sheet (CCVS) Battery Draw worksheet may be helpful in isolating or duplicating a customer’s concern. Use the information during the road test to verify operation according to the customer’s description of the condition.
A link to the worksheet is included in the Battery Electrical Drain/Parasitic Load Test document in SI. The worksheet also can be found in GM GlobalConnect. From the Service apps, launch Service Forms and select CCVS Battery Draw

All Customer Concern Verification Sheets (CCVS) have been designed to improve communications between service customers and technicians.
The more clearly concerns and related symptoms are understood, the more likely the concern will be fixed quickly and accurately.

System Operation

When diagnosing a parasitic draw, keep in mind the power-down and wake-up process for most control modules.

After the ignition is turned off, the control modules will begin to go to sleep (shut off).
However, not all control modules go to sleep at the same time. Some control modules may take up to 30 minutes or longer after turning the ignition off before going to sleep (e.g. Retained Accessory Power).
Other components, such as EVAP, HVAC Afterblow, EV Battery Heater/Coolers, OnStar and Remote Keyless Entry (approach detection in keyless access vehicles), may periodically wake up control modules and then go back to sleep, depending on vehicle status. These are all normal conditions.

Most vehicle systems will go into the initial sleep cycle after 10;minutes.
With periodic normal wake up cycles that will occur for approximately one;second, it can take up to two ;hours before all systems power down completely.
Typically, a vehicle will not have more than a 50;mA parasitic draw during the initial power sleep cycle.

There are many things that can prevent the vehicle from completely going to sleep and passing the parasitic draw test, such as the key fob not moved away from the vehicle (for keyless access vehicles); the approach, exit, or delayed lighting not disabled; or HVAC After blow, which is enabled at the factory on some 2021 models, cannot be disabled.
Some vehicles can have the power supply port changed to “ON” with the key off to allow for accessories to stay powered (e.g., phone charger).

Ensure all aftermarket accessories are unplugged prior to testing.

The use of a Digital Multimeter (DMM) set to Min/Max may help identify the normal spikes in the parasitic draws.

GM will start selling car insurance again, this time using data its cars collects from customers' driving habits to determine their rates.

Drivers who obey
speed limits and show other good road behaviors will receive lower rates, the company said

The system will initially spy on your acceleration, braking and general usage data but eventually could factor in how many times a customer used driver-assisted technology or even how well inflated their tires were.

Plans will be offered under GM's OnStar connected-car service, a standard with all GM vehicles in the US, and will be optional for drivers.
A pilot program starts this week with GM employees in Arizona, with a nationwide rollout expected by the end of 2021.

The company left the insurance business in 2009, when it declared bankruptcy and spun off GMAC financial services as Ally Financial.
GM says it envisions integrating its new insurance service with its other OnStar services, so agents can get accident information quickly and replacement parts can be ordered, saving time and money.

OnStar Insurance Services, which will also offer homeowner's insurance, is being launched in partnership with American Family Insurance, which will underwrite policies.
The system will also build upon the Onstar Smart Driver system's AI to provide proactive recommendations for safer driving, potentially improving customers' rates even further.

But OnStar Insurance Services 'takes biased judgement out of insurance shopping by focusing on factors within the customer's control and rewarding smart driving habits that benefit road safety,' GM said in a statement.

Rates will initially be set like typical insurers, but as customers rack up a driving record on their GM vehicle, their rate will adjust.
The system will initially focus on acceleration, braking and general usage data but eventually could factor in how many times a customer used driver-assisted technology or even how well inflated their tires were.

'We're not the only automaker out there with connected vehicles, but we have more data collected than the rest of the industry combined,' said OnStar Insurance Services President Andrew Rose. 'We aim to be an industry leader.'

According to the OnStar Insurance website, customers could receive a discount of up to 20 percent on their premium, based on their record.
Plans will be made available to cars not using OnStar, but not all discounts will be available to vehicles without it.

OnStar Insurance still has to be approved by various state insurance commissions, but GM expects to have it available nationwide by the end of next year.
'Data is increasingly a focal point for insurers as it enables rate adjustment based on behavioral metrics such as driver phone use and propensity for heavy braking,' data analyst Asad Hussain told Business Insider.

Depending on the ,model year,

Many years GM used a "Starbus" network (like a ring network) so all the controllers were in series of network
thus there is a send and receive pairs that need to be looped back to get the network path healed
So in that case would have 2 paired paths to loop back

What if you just looped it back right before the antenna? That would keep all internal systems normal just kill the external connection in theory lol

I got this from *************** that I'm on:

It turns out that the Onstar VCIM is integral to the high-speed communication bus between the BCM at one end of the chain and the ECM at the other. So removing it stops the high speed bus operation between modules, hence the major issues.

Thus, removing the VCIM will cause a major vehicle malfunction.
