DI_a179_steeringAngleOffsetWarning
Also written as DI_A179 / DI A179 / DI_a179_steeringAngleOffsetWarning / di_a179_steeringangleoffsetwarning
Why does the exact Tesla alert ID matter?
Record the exact alert ID, including underscores, suffixes, and companion alerts. Tesla alerts that look similar can point to different modules, timestamps, and service procedures.
What does DI-A179 mean?
Tesla alert code in the Drive Inverter (DI) module. Drive Inverter User Alert: Steering Angle offset nearing plausibility threshold Steering angle offset exceeds warning threshold User has vehicle alignment performed at service center Steering angle offset may fault stability and traction control if the magnitude continues to increase. Drive Inverter Warning: Traction control CAN node is MIA Drive Inverter Warning: 12V supply under voltage detected in software 12V supply voltage to DI (refer to 12vSupply) is disconnected or drops below lower voltage threshold 12V supply rises back above lower threshold

Affected Tesla Models
What You May Notice
- DI-A179 may appear with another Tesla alert in the Drive Inverter (DI) system.
- The vehicle may limit charging, driving, comfort, or safety features depending on the active alerts.
- The alert may clear after sleep, but recurring alerts should be treated as service-relevant.
How to Diagnose and Resolve
- 1 Reboot the vehicle (hold both scroll wheels)
- 2 Check for pending OTA software updates
- 3 Monitor for recurrence over the next few days; schedule service if needed
Severity Notes
DI-A179 is an Alert in the Drive Inverter system. Confirm the vehicle screen and Tesla app show no driving or charging restrictions, and schedule service if the alert returns.
