This one?


The problem is DTC U0028:88-2F - Vehicle A communication bus (bus disabled). This is not the car's fault. The DTC was stored before the crash was cleared via CAN by AST and is still there after the work is done.

Its not problem on car side.! I check, second unit work ok. Mayby configuration or somthink else i my unit... Not have at the moment this car, only srs unit.

If you have a dump please add.

I managed to solve the off-topic issue. The customer provided a second Mustang, I read it and write it to the damaged SRS. Now everything is OK, there is no U0028 error. Regards.
