Tesla LDU Inverter Control Board 1013416-00-E REV03 — DI_F072 fault — EEPROM reset help needed

[Olo3323]

Hello everyone,

I'm working on repairing a Tesla Large Drive Unit inverter
control board with the following details:

Part number: 1013416-00-E REV03
Serial: 2116E60000795
Fault: DI_f072_gateDriverFaultCounter / DI_w072

The drive unit has been removed from the vehicle and is
on the bench.

IGBT diode test results:
- All phases show approximately 0.4-0.5V in diode mode
- No short circuit detected (0.000V)
- Gate resistors appear to be in normal range (not in MΩ)

Based on this, I believe the IGBT modules are physically
OK and the fault is latched in the EEPROM of the control
board — not a hardware failure.

My questions:

1) Can anyone confirm that DI_F072 on this specific board
(1013416-00-E) is stored/latched in the EEPROM chip?

2) What is the exact EEPROM chip type on this board?
(95128? 95256? other?)

3) Does anyone know the hex offset / address in the EEPROM
where the fault counter is stored?
What bytes need to be zeroed out to clear DI_F072?

4) I have a CH341A programmer and SOIC8 clip ready.
Is it safe to read/write the EEPROM in-circuit
(without desoldering)?

I have already read about EV Clinic file service as an
option, but I would prefer to understand the process
myself first if anyone has already reverse-engineered
this.

I can share my EEPROM dump here if that would help
the community document this for future repairs.

Thank you very much in advance!

Hey, were you ever able to figure this out?

I have the exact same issue and have been trying to fix it for a while! In my case, there was a bad IGBT diode but I replaced the phase module, yet the error still remains.

I also read about the EV clinic one but I don't want to spend more money than a board costs to have them do it, this can't be impossible to figure out.
