Mazda CX-5 Service & Repair Manual: Blind Spot Monitoring (Bsm) Control Module Inspection
1. Disconnect the negative battery cable..
2. Remove the rear combination light..
3. Remove the rear bumper..
4. Connect the negative battery cable..
5. Verify that the voltages of each of the terminals are as indicated in the terminal voltage table (reference).
-
If the voltage is not as specified in the terminal voltage table (reference), inspect the parts under Inspection item(s).
-
If the system does not operate normally even though the inspection items are normal, replace the BSM control module (RH) or BSM control module (LH).
