Solved: YANHUA ACDP Module 45 “Write Routine Data Error”

Problem: A customer used YANHUA Mini ACDP + Module 45 and encountered the error “Write routine data error.” The diagram showed a 7-pin connector, but the customer’s interface had a 10-pin connector.

Engineer’s Answer: The system information showed that BOOT version bh1g0301 was an older version associated with the 10-pin connector. The customer needed to select the corresponding 10-pin operation option.

Solution

1. Check the system information and confirm the BOOT version is bh1g0301.
2. Select the appropriate 10-pin connector option for the target transmission:

DQ380 (0DE)

DQ381 (0DE)

DQ500 (0DE)

DQ500 (0BH BOSCH)

DQ500 (0BH CONTINENTAL)

3. Follow the operation instructions for the selected 10-pin option.

Final Result

Selecting the correct 10-pin operation option should resolve the “Write routine data error.”
