U0222 Lost Communication With Door Window Motor A

Check engine lightUsually off

EmissionsNot relevant

Drive cycleNot required

Limp modeNo

U0222 says door window motor A, a motor with its own electronics, is no longer heard. GM uses it on 2021–2025 Escalade, Tahoe, Suburban and Yukon with air leveling (RPO F47): PIT5981B lists U0222 to U0225 as codes that can sit beside a low or leaning air suspension, a Service Leveling System message or short-term inflates that do nothing. The link is the door-ajar switch, wired directly to each window motor; while a motor is silent, the door state is unknown and the scan tool shows closed by default. GM saw this mostly on upfitted vehicles such as armored cars or limousines. On its 2014–2018 trucks GM still used its own U1534 for the driver window motor. No MIL.

Likely causes

Door wiring altered or damaged during an upfit (armored car, limousine)

Broken bus or supply wire in the door harness

Electronics of window motor A failed

Water or corrosion at the motor connector

Symptoms

Air suspension low, leaning or not leveling
Service Leveling System message in the driver information center
Door shown as closed in scan data although it is open
Window in the affected door does not move
