Code DGLAB_i005 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.
Drive Inverter Warning: Excess Heat Unavailable (unexpectedly)
Drive Inverter Warning: No capable drive units detected
No drive units found that can produce torque
One or more drive units can produce torque and drive cycle is executed
Unable to produce any torque or power
Drive Inverter User Alert: TC Reduced by ADD
Active driveline damping (ADD) has degraded its state. This reduces the functionality and performance of Traction control. Check for other DI alerts prior to this that provide more detail to the specific cause.
This alert will clear once addState returns to NORMAL and all other Traction control input signals have become available.
Drive Inverter Warning: Accel pedal track 2 bad
Drive Inverter Warning: System limp mode triggered
Abnormal operation detected in the powertrain system. Look at limpReason in alert for exact trigger.
Reason for trigger is not present and drive cycle is executed
Drive system performance severely reduced (torque/power limited)
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.
