Code DGLAB_i019 was reported by the “Diagnostic log entries” controller in the car. The letter “i” in the middle places it among entries of the information type.
Internal diagnostic and informational events the car records for service. These are not faults — more like notes that some condition returned to normal.
A purely informational record of a state change. Usually it means something returned to normal.
This is how the fault is named inside the car's firmware. For codes without a description it is the most precise clue there is — the name itself says what the event is about.
The text below comes from Tesla's technical documentation. We leave it in the original English so that translation cannot shift its meaning.
Radar functions are disabled and autopilot features will be disabled.
ECU Internal fault - Internal CRC Failure
Radar Environmental Model (EM) was Reset
ECU Internal ADC underVoltage - Indicates an under voltage condition for the following voltage rails 1V25, 3V3, 4V5, 5V
Set when the voltages for the respective rails are above threshold
Cleared when over voltages return to nominal level
The restraint system may not function as designed.
There is a fault with the left C-Pillar impact sensor.
The restraint controller has not learned the vehicle VIN or detects a VIN mismatch.
The VIN is learned or the mismatch is corrected.
Copy it exactly, letter and number included. Photographing the screen is safest — codes often differ by a single digit, and mixing them up leads somewhere else entirely.
Some codes clear after a screen restart or after the car sits locked for a few hours. If the code does not come back, it was usually a one-off glitch.
A one-off entry and a code that appears after every drive are two different things. It helps a service centre enormously if you know exactly when it shows up.
With airbags, brakes, steering and high voltage there is no point waiting it out. With the other groups you can watch and see whether the code returns at all.
Error codes are only part of the picture. For cars on TesList you also see battery health pulled straight from the vehicle, plus a price calculator that works out from current listings what a given car is actually worth today.
