On star email 'ABS Diagnostic Alert'

[Brian Maxwell]

My emails have said 'ABS Diagnostic Alert'for quite some time.  Started a bit after a tpms sensor stopped reporting (don't care) and that light came on.  Ironically, the emails report all 4 tire pressures but ones missing on the truck menu.

No ABS light so I'm not super concerned but figured it's worth asking if I should do something.

 

Thanks.

I would at least find a code reader that can get codes from the ABS system, to see what problems it has noticed.

I agree. I have often found intermittent faults can be corrected by a simple scan and reset of codes.
Many times it's because of either a low battery issue or a grounding cable with an intermittent connection.
Also, inflate all of the tires to the same PSI, prior, and drive about 10 miles or so.

Ironically my Chevy App has been saying to service my ABS too??? Hmm, wonder if there is a glitch in their system?

Been going on for about a month now, just won't clear out, nothing going on in the truck, no lights, no warnings.

I'm sure you already ran a scan and cleared all codes?
When I ran my battery down by leaving my dash cam on for two days without driving, the app alerted me to a myriad of issues.
I recharged (and reconditioned) the battery, ran the diagnosis on my Autel, erased all codes - most were legacy.
Afterward, all was good.
