Drive System Limp Mode — Torque and Power Severely Limited by the Rear Drive Inverter
The TESLA-DIR_A062 (Tesla DI/DIR (drive interface / rear drive inverter)) EV fault code means: Drive System Limp Mode — Torque and Power Severely Limited by the Rear Drive Inverter. This is a serious severity code.

- Depends entirely on the companion fault, because this alert reports the protective response rather than the cause. A single self-clearing occurrence may need nothing; a repeating one needs Tesla to read the alert payload.
A $30 car code reader can't do diesel. The HD7000 reads full-system codes and does parked DPF regen, idle/speed-limit, and service resets from the cab — on everything from a 6.7 Cummins/Power Stroke/Duramax pickup to Class-8 trucks (Detroit, Paccar, CAT, Volvo, Mack, International).

Common Symptoms
- Touchscreen shows "Power reduced" and "Exiting and re-entering vehicle may restore operation"
- Acceleration is dramatically weaker than normal
- The car still drives, but torque and power are severely limited
- Behaviour may return to normal after a stop, or after leaving and re-entering the car
Probable Causes (Ranked by Likelihood)
- The drive interface or drive inverter control unit detected abnormal operation somewhere in the powertrain and put the drive system into limp mode deliberately. This alert reports the PROTECTIVE ACTION, not the underlying fault. High
- A companion condition logged at the same time is what actually triggered it. Tesla's own note is that the alert log signal data identifies the specific condition detected — which is why the other alerts present matter more than this one. High
Frequently Asked Questions
What does DIR_a062 mean?
Its firmware name is DIR_a062_systemLimpMode. The drive interface or drive inverter control unit detected a condition in the powertrain that made it trigger system limp mode, so torque and power are severely limited.
Can I drive with DIR_a062?
The car drives, but with severely limited power. The vehicle message is "Power reduced — Exiting and re-entering vehicle may restore operation". Drive conservatively and expect weak acceleration; do not plan on normal merging performance.
Why does DIR_a062 not tell me what is wrong?
Because it reports the response, not the cause. The control unit logs the specific condition it detected in the alert payload, and any companion alerts showing at the same time are usually what point at the root fault.
How common is DIR_a062?
Tessie's owner-telemetry puts its live incidence rate below 0.01%, which it classes as extremely rare.

Step-by-Step Diagnostic Procedure
Treat the reduced power as real. The car is drivable but the drive system is deliberately limited, so plan for weak acceleration when merging or pulling out.
Try the car's own suggestion: park safely, exit the vehicle, lock it, wait, then re-enter. The alert text says this may restore operation.
Record every OTHER alert showing at the same time. This one says limp mode was triggered; a companion alert is what says why.
Note whether it clears on the next drive. The clear condition is a drive cycle in which the control unit no longer sees the trigger condition — so a single occurrence that does not return is different from a repeating one.
If it repeats, book service and bring the alert list with you. The specific condition lives in the alert log payload, which needs Tesla's tools to read.
