Random / Recurring 'Check Engine Light'
I wanted to ask this forum if anyone else has had an issue with the 'Check Engine Light' (CEL) illuminating randomly with no associated DTC?
This issue eventually progressed to a point where the CEL would illuminate and trigger the 'Limp Mode.'
The bike would run on one cylinder for a while (like a fouled spark plug) then clear and both cylinders would return. The CEL would remain on with no DTC until I cleared all DTCs.
That procedure would clear the CEL until the next event.
Recently, the CEL illuminated and 'Latched On' with the triggering Limp Mode and I was able to recover the following DTCs:
DTC code C110468 on a 2024 CVO Road Glide ST, often accompanied by code P180000C, is commonly linked to loose or disconnected wiring plugs. This issue, sometimes causing limp mode, is often traced to unseated electrical connections, specifically around the handlebars or fairing, requiring inspection of all plug connections.
The P230000 code on a 2024 CVO Road Glide ST indicates an Ignition Coil A Primary Control Circuit Low issue. This often points to a faulty ignition coil, damaged wiring, or a loose connector, resulting in engine misfires, power loss, or a "limp mode" scenario, potentially related to handlebar modifications or loose connector pins.
DTC code P013400 on a 2024 CVO Road Glide ST indicates Oxygen Sensor Circuit No Activity Detected (Bank 1, Sensor 1), meaning the ECM sees no response from the front upstream O2 sensor. This is often caused by a failed sensor, damaged wiring, or improper connector seating, particularly after service, exhaust work, or handlebar
DTC code P013500 on a 2024 CVO Road Glide ST indicates an Oxygen (O2) Sensor Heater Circuit Malfunction (Bank 1, Sensor 1), meaning the ECM detects an issue with the front sensor's internal heater. Common causes include a failed front O2 sensor, wiring harness damage, or a blown fuse.
SB M1700 was complied with last Fall.
Has anyone else seen this?
Thanks for your help!

"SB M1700 was complied with last Fall." ...so you had SB 1700 repair performed or did they do the inspection to determine if it needed the repair kit??
I haven't had that many codes but on my 24 RG after it was acting up it had a CEL with Ignition Coil code, they replaced the coil and the problem didn't recur for the few months I had the bike before trading in due to more problems I'd had enough with. SB M1700 was not yet published when they replaced the coil because they had nothing else to go on it pointed to the coil failure. FF to this month, and this began "The bike would run on one cylinder for a while (like a fouled spark plug) then clear and both cylinders would return." Mine continued this intermittent behavior until it kept getting worse and then the CEL came on and stayed on with a code. Our Master tech put it on the dyno and was able to reproduce and identify faulty ignition coil wiring problem and is installing the M1700 repair kit. Aren't these new gen 2 CC models awesome! It's so exciting going down the road in traffic when this $h!t happens. I figure I'll just ride from now on with my Emergency Flashers on at all times. Doesn't seem if, but when, they'll be needed again.

Full Disclosure, I brought the issue to the attention of my Service Manager.
He told me that the Master Tech who does all my work was aware of SB M1700 and would take care of it for me.
Not sure how much inspection took place, but I have complete confidence in the Master Tech.
He has been at the dealership for many years and has built several motors my son and me.
Anyway, today after snapping the image above, I cranked it up and there was no CEL or DTCs present.
Maybe I'll take it for a quick rip this afternoon and If I get no CEL or Limp Mode, I'll roll the dice on a 135-mile ride to the dealership with the Emergency Flashers on.
Just kidding!

Excuse me for not being so tech orientated, but I had a similar issue to my 24 road glide again today ..as I look back on this thread. It happened to me about a year ago when I first got the bike the CEL came on.Now that Ive read this thread. Im driving in traffic and my bike engine stopped. I had to restart it and it was a little rough maybe it was in limp mode. Im not sure.After I started it it took off and I was able to get home with not any issues, but my CEL was still on.
The service manager at Southside Harley is a great guy and a friend he walked me through going into the diagnostics and seeing if theres any yeses like it was throwing a code there were none so he told me to go out and drive around and start and stop the bike a few times and it will clear the CEL light.I did this, but on my initial restart, the check engine light was gone and the bike was running like a top.I hated that these bikes are so finicky but when theyre running good, theyre great
Just my two cents

can you really tell a serious addition of power?
This forum is really great and full of useful information
Im gonna talk to my dealership about this M1700 repair kit nobody wants to get stranded on the road and try to limp Home on one cylinder that would really suck .. I just watched a YouTube video from eight months ago where a guy had a limp home from Sturgis on one cylinder and made it all the way home and his bike was not throwing any codes. Everything looked clear in the check engine light was not on when it happened after it happened. The CEL came on.
