REPAIR PROCEDURE
1. Verify the customer concern of the (BSM) OFF indicator light flashing in the instrument cluster and that DTC
U3000:54 is stored in memory.
2. Visually inspect the rear bumper surface for excessive dirt, scratches, deformities or foreign material
attached to the bumper. These can all affect the BSM from operating properly.
- If the rear bumper surface has any of the above, clean or repair the bumper surface, then re-test the BSM
system.
- If the rear bumper surface is clean and in normal condition, proceed to step 3.

NOTE:

Even a minor impact to the bumper can cause a misalignment of the BSM, which may also
cause DTC U3000:54 to be stored in memory. However, this is not covered under warranty.
Re-align the module and re-test the BSM.

3. Replace both side BSM control modules with modified parts according to the instructions on MS3 online or
the Workshop Manual (section 09-22).
