Problem:
CG Pro 9S12 programmer failed to erase a BMW 35160WT chip.
The same chip previously worked normally three or four times under other circumstances, but the last three attempts always resulted in freezing, failing to clear the mileage data.
I tried heating it, but it had no effect. I even left one chip to clear data overnight, but the next morning, the data remained unchanged—still showing 0%.
Other two 35128WT EEPROM chips encountered the same problem.
Solution:
CGPRO 35160WT Erase Heating Method Instructions (For chips that cannot be erased normally):
Preparation:
Set the hot air gun to 100°C.
Heating Process:
Heat the chip (while soldered on the board) for 20–30 seconds.
Stop heating, then immediately attempt the erase operation.
Cooling & Retry:
If the chip still fails to enter the second-stage erasure after fully cooling down, repeat the heating process (20–30 seconds).
Note: The chip may successfully erase during the cooling phase.
If still not working after doing above, initialize CG pro device and try again.
