Colorado/Canyon: EBCM connector intrusion can mimic sensor faults. See the manufacturer document, vehicle conditions, exclusions and questions for a qualified shop before assuming a repair.
This is a research summary of a manufacturer communication, not a diagnosis for your car, a DIY repair procedure or confirmation of warranty or recall eligibility. No qualified technician has approved a repair for your individual vehicle here.
This historical communication is conditional. The current revision, VIN/build eligibility, measured diagnosis and any warranty or recall decision are not established here. Ask the manufacturer or a qualified shop to check the complete current document.

What prompted this manufacturer document
- Water/corrosion at an EBCM connector can accompany ABS/StabiliTrak, trailer-brake service or low-fluid indications even when the reservoir is full.
Which vehicle conditions must be checked
Each row below retains its own conditions. Do not combine engines, years or models across rows to create new applications. A listed model is not proof that a particular VIN is affected.
- Chevrolet Colorado · 2015, 2016, 2019
- GMC Canyon · 2015, 2016, 2019
- The source lists 2015-2016 and 2019; do not add 2017-2018.
- A full reservoir does not establish that braking is safe.
Codes recorded in this document
A root listed only as an appearance has no separately verified meaning here. Preserve every suffix and module name; a shared root does not transfer a repair branch to another vehicle.

What an owner can record safely
- Photograph warning combinations and report water exposure or recent wiring work.
What the source does not prove
- Do not bypass warnings or start replacing individual wheel sensors without a network/connector assessment.
- A code or message alone does not establish a failed part, a safe-to-drive decision or an approved repair for this VIN.
- A service bulletin is not automatically a recall or free warranty repair. Confirm current eligibility directly.
Questions for the repair shop
- Was the EBCM connector checked for water before a sensor or module was condemned?
- Does a later revision or a current recall change the source's original advice?
- What measurement or inspection confirms the cause, and how will the repair be verified?
Open source-review issue
- Q2-011: The source shows its issue date as N/A. No exact issue date is claimed for this record.
The uncertain field is not used here to claim a current fitment, repair or market-wide failure.
