Diagnostic Procedure

Step	Inspection		Action
1	INSPECT INSTRUMENT CLUSTER •  Turn off the MRCC warning light (amber) using the M-MDS instrument cluster active command modes WL+IL. (See ACTIVE COMMAND MODES INSPECTION [INSTRUMENT CLUSTER].) •  Are all the warning lights turned on/off?	Yes	Go to the next step.
		No	Replace the instrument cluster. (See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)
2	VERIFY INSTRUMENT CLUSTER CONNECTOR CONDITION •  Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-D 2.2].) (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5].) (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5 (WITHOUT i-stop)].) •  Disconnect the instrument cluster connector. •  Inspect the connector engagement and connection condition and inspect the terminals for damage, deformation, corrosion, or disconnection. •  Is the connector normal?	Yes	Go to the next step.
		No	Repair or replace the connector.
3	VERIFY VEHICLE CONTROL MODULE CONNECTOR CONDITION •  Disconnect the vehicle control module connector. •  Inspect the connector engagement and connection condition and inspect the terminals for damage, deformation, corrosion, or disconnection. •  Is the connector normal?	Yes	Go to the next step.
		No	Repair or replace the connector.
4	INSPECT CRUISE CONTROL SWITCH •  Inspect the cruise control switch. (See CRUISE CONTROL SWITCH INSPECTION [MAZDA RADAR CRUISE CONTROL (MRCC) SYSTEM].) •  Is the cruise control switch normal?	Yes	Go to the next step.
		No	Replace the cruise control switch. (See CRUISE CONTROL SWITCH REMOVAL/INSTALLATION [MAZDA RADAR CRUISE CONTROL (MRCC) SYSTEM].)
5	INSPECT VEHICLE CONTROL MODULE •  Inspect the vehicle control switch. (See VEHICLE CONTROL MODULE (V/C-MODULE) INSPECTION [MAZDA RADAR CRUISE CONTROL (MRCC) SYSTEM].) •  Is the vehicle control module normal?	Yes	Symptom troubleshooting is completed.
		No	Replace the vehicle control module. (See VEHICLE CONTROL MODULE (V/C-MODULE) REMOVAL/INSTALLATION [MAZDA RADAR CRUISE CONTROL (MRCC) SYSTEM].)
