Forward Collision Alert Light with Braking Set to "Alert"

This is meant to be informational and hopefully a time saver for some. 

 

I had a 2022 Silverado 1500 and currently own a 2025. In both of those vehicles I have always set "Automatic Emergency Braking" and "Front Pedestrian Braking" to "Alert" (instead of "Alert and Brake" or "Off"). 

 

These settings never caused the forward collision warning light to illuminate, until some point in the last couple months (possibly due to a software update?). Now having braking turned off on either of these settings causes the light to be illuminated all the time. 

 

I wasted a lot of time trying to figure out why the light was constantly illuminated, not knowing the display logic had changed. The only way to clear the amber light is to have both forward collision modes set to "Alert and Brake."

 

I assume this was done out of some liability concern, but it is frustrating that selecting a normal operating mode (Alert) causes the fault indicator to be illuminated all the time, preventing the system from indicating whether an actual fault is present. 

 

I hope this helps anyone looking into the same issue.

So...just turn them back on?  You don't want your truck to automatically brake for a pedestrian?  

 

The point of this post was not to start an argument. It was to provide useful information to anyone troubleshooting problems with the forward collision system. 

 

The way the system indicates problems is counter-intuitive enough that a TSB was created to specifically address it.

I just noticed, today, that the FCA light is on for my 23 Sierra 1500. I cleaned the front (bumper) sensors since I've had alerts from those being blocked/dirty before. Mostly in the winter due to the snow/crap that gets kicked up from the road. I checked the settings in the infotainment system and it's all as they were before the light went on (alert and brake). I'm wondering if this is just another bug in the latest OTA update that was sent out. Since it also removed the displaying of new audio tracks on the HUD that were present before the update. I can get that to show IF I hit 'skip' via the steering wheel controls.

 

I'm going to try disconnecting the negative battery terminal in the morning to see IF that helps clear the issue. I really don't want to go to the dealership over this item. I know the sensors are working since they alert me, as they should, if I'm getting too close to something (typically when parking). 

 

Anyone else have this annoying issue for the FCA and get it to go back to cleared? I do have a BlueDriver module that shows no codes on the truck. Not sure how deep that can go though. It did show a 'low battery voltage' alert which I'll check on again later. At just over three years old, I'm sure I'll be needing a new battery soon. Especially since I put about 12k miles on it over the previous three years. Need to start researching batteries to replace the original with, but that's another thread/issue.

 

--update--

Disconnecting the battery (negative terminal) for about ten minutes seems to have cleared the light. Will see if it stays off on subsequent runs. Annoying how it does the 'theft detected' deal from this. At least it retained all my settings. Including seat positions. 😃

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By asilverblazer · Posted

      Length/amount of data capture will be important to consider, sifting through 5 minutes of a data log can be enormous when it is stored in milliseconds. Being able to find the 'event' let alone decipher it.   Presumably the driver would notice something and hit a button to capture the 'window' of data. That window has to be large enough for the operator to recognize the event and react accordingly.    The data has to be able to be retrieved easily.   The data has to be able to be understood. Which is the biggest challenge, dealer techs won't even know what most of it is and would likely not even look at it if an owner brought it to them. Meaning the owner, the least educated/qualified, trying to understand it.    How will the data be presented? Could specific PIDs be selected and a timelapse graph be watched? How will a specific value be noted as abnormal? Additionally, a good data logger would be able to 'learn' normal values for a specific vehicle and flag abnormalities automatically. It could in theory watch parameters degrade over time and suggest maintenance as needed. (If the MAF reading begins tapering off for a given set of other readings - MAP, throttle position, Ambient, etc.. a flag to check air filter.) With the amount of data available, a device (really the vehicle rather than an additional accessory) should be able to do more than issue a DTC. It should be able to run the full diagnostic suite automatically and present a solution rather than a code. (It's not the 90's anymore). The technology is available for the vehicle to not just say "P0087", it should know low fuel pressure, check other PIDs to narrow down the problem itself, and determine if it is a lift pump, high pressure pump, regulator, leak in the fuel line, clogged filter, etc. Even if it can't narrow it down, it should be able to guide the user to the likely problems.   This would be a major problem for dealer service departments, which are the manufacturers customers it is in their collective best interest to NOT have this available to the consumer.   Further, if the owner is going to be the primary consumer of the data, it's got to be at a consumer price point vs. dealer only specialty tool price.   This group is more 'involved' in their vehicle than general public/consumer and will have knowledge, experience, needs and desires that are quite different from the market at large.

      OCI, not when but why?

      I put the prof up. If you read what I posted. You can see that housing, cars and income are in line with the era we were talking about. It’s harder in some places easier in others. Let’s agree to disagree and put this back on track, OK? We both are pretty stubborn and hard headed. But I bring receipts. If you wish I will not respond to you in the future.

      Lets see if I can sum up two pages of nothing useful.    You want to refute your own governments data of the "Purchasing Power" Index FOR THE ENTIRE USA and its territories replacing it with the experience of a single family and its business and label that reality?  Then pound on that for a week hoping it will find traction?    Stan, I've told you several times. I don't do irrational. There are more people in the USA than your family.    I'm pretty sure this tread is so blown up. I'll give you a few days or months if need be to post yourself silent then I'll see if I can find enough parts of the train to reassemble it.

      VSE CCV Bypass - Anyone have this installed in their L5P?

      By asilverblazer · Posted

      Facebook groups hate VSE, poor customer service; their responses to criticisms are pretty poor for a reputable company. I'm not a customer, haven't bought anything from them, but how they handle themselves on social media is a definite "No" for me.

      Transmission Woes :-(

      By asilverblazer · Posted

      $10,000 for a transmission?   Pretty sure I could buy all the parts, tools, and education to rebuild it myself for a quarter of that amount.   or swap it out with a new one...
