Diagnostic Procedure

Step	Inspection		Action
1	RECORD THE CAR CONFIGURATION DATA •  Switch the ignition ON (engine off) and wait for 6 s or more. •  Switch the ignition off. •  Switch the ignition ON (engine off).		Go to the next step.
2	PERFORM DTC INSPECTION FOR VEHICLE CONTROL MODULE (V/C-MODULE) •  Clear vehicle control module (V/C-module) DTCs using the M-MDS. (See CLEARING DTC [VEHICLE CONTROL MODULE (V/C-MODULE)].) •  Switch the ignition ON (engine on). •  Perform the vehicle control module (V/C-module) DTC inspection using the M-MDS. (See DTC INSPECTION [VEHICLE CONTROL MODULE (V/C-MODULE)].) •  Is the same DTC present?	Yes	Repeat the inspection from Step 1. If the malfunction recurs, go to the next step.
		No	Go to Step 6.
3	PERFORM DTC INSPECTION FOR INSTRUMENT CLUSTER •  Perform the instrument cluster DTC inspection using the M-MDS. (See DTC INSPECTION [INSTRUMENT CLUSTER].) •  Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [INSTRUMENT CLUSTER].) Then go to Step 5.
		No	Go to the next step.
4	PERFORM DTC INSPECTION FOR VEHICLE CONTROL MODULE (V/C-MODULE) •  Clear vehicle control module (V/C-module) DTCs using the M-MDS. (See CLEARING DTC [VEHICLE CONTROL MODULE (V/C-MODULE)].) •  Switch the ignition ON (engine on). •  Perform the vehicle control module (V/C-module) DTC inspection using the M-MDS. (See DTC INSPECTION [VEHICLE CONTROL MODULE (V/C-MODULE)].) •  Is the same DTC present?	Yes	Replace the radar sensor, then go to the next step. (See RADAR SENSOR REMOVAL/INSTALLATION [MAZDA RADAR CRUISE CONTROL (MRCC) SYSTEM].)
		No	Go to the next step.
5	VERIFY THAT REPAIRS HAVE BEEN COMPLETED •  Clear vehicle control module (V/C-module) DTCs using the M-MDS. (See CLEARING DTC [VEHICLE CONTROL MODULE (V/C-MODULE)].) •  Switch the ignition ON (engine on). •  Perform the vehicle control module (V/C-module) DTC inspection using the M-MDS. (See DTC INSPECTION [VEHICLE CONTROL MODULE (V/C-MODULE)].) •  Is the same DTC present?	Yes	Repeat the inspection from Step 1. •  If the malfunction recurs, replace the vehicle control module (V/C-module). (See VEHICLE CONTROL MODULE (V/C-MODULE) REMOVAL/INSTALLATION [MAZDA RADAR CRUISE CONTROL (MRCC) SYSTEM].) Go to the next step.
		No	Go to the next step.
6	VERIFY THAT NO OTHER DTCs ARE PRESENT •  Verify other DTCs displayed. •  Are any other DTCs output?	Yes	Perform the corresponding DTC inspection.
		No	DTC troubleshooting completed.
