2025 JLUR Remote Start Does Not Work

[Mguy]

@THAW's latest remarks in response to my last post, #29, are too much of a thread drift--and are too inane--for me to respond. Significantly though, the subject of IBS inaccuracy in calculating SOC is well known to Jeep engineers ("Symptom/Vehicle Issue . . . Intelligent Battery Sensor (IBS) State of Charge (SOC) Inaccurate."). Jeep's solution is to reset the IBS, which is easy to do ("In most cases, the IBS can self-recover from a functional software defect if the two-way connection gets cycled (i.e., resets/reboot the module)).

However, if forum members express interest, I'll provide some explanation and elaboration in a new thread on the subject. Otherwise, I consider the issue of IBS inaccurate reporting of start battery SOC a known, but closed, subject.

The continual misrepresentation of that Star Case and recommendation to reset the IBS in general circumstances are very unfortunate.

It's the height of irony the same forum member who in this thread repeatedly doubted the concept IBS SOC data can deviate significantly from resting-battery-voltage SOC estimates just cited his long-time-favorite Star Case to confirm it's a "known, but closed, subject". That his post is framed as if he understood the possibility all along, is dedicated to preventing the "thread drift" he initiated and helped propagate, and is above addressing the antecedent factual explanations of SOC tracking because they're allegedly "inane" "remarks", is hypocritical to the point of absurdity.

I suggest ignoring @Mguy's posts regarding the IBS (and frankly all his riddled-with-bad-assumptions JL charging posts), as it's quite clear he's guessing wildly based on poor interpretation of online documents while refusing to test his (often disproven) theories against his own easily accessible IBS data.

Since my posts in this thread ended 4 days ago, according to someone on this forum, @THAW has edited his remarks in posts #30 and #32, both directed at me, approximately a dozen times. Seems that he's moved from "inane" comments, added some actual facts, and now wants a response from me.

As I said before I'd participate in a discussion of IBS inaccuracies of SOC estimates if there was forum member interest. There appears to be none in this thread, perhaps because of the subject drift. So my message to @THAW is simple. Start a new thread if you think the subject is forum-worthy.

I encountered a similar problem before, and no matter what I tried, it didn't work. In the end, the technicians solved it by refreshing the remote boot module program through the OBD interface.
