Locking/unlocking problems

Plytic · 02-28-2021, 03:32 PM

Hello,
I have locking and unlocking problems.
The fuses is fine. Sometime its working sometimes not.

When its not working, i can only lock the driver door and trunk sometimes.

Codes:
A6CF
A6D4
A6D5
A6E8

Do i need to replace the JBBF module or do you have some idea?

Is the battery run down, alternator issue?

A6CF= JBE: AUC sensor
A6D5= JBE: Central-locking relay, unlocking
A6D4= JBE: Central-locking relay, locking
A6E8= JBE: Central locking, repeat interlock
