Description

MRCC INDICATOR LIGHT (GREEN) IS NOT ILLUMINATED DURING MRCC OPERATION

•  The MRCC indicator light (green) is not illuminated even if the MRCC is operated.

Possible Causes

•  The instrument cluster cannot illuminate the MRCC indicator light (green).

―  Instrument cluster malfunction (malfunction in MRCC indicator light (green) illumination circuit)

―  Connector connection malfunction

•  The vehicle control module cannot illuminate the MRCC indicator light (green).

―  Connector connection malfunction

―  False signal input from cruise control switch

―  Vehicle control module malfunction

Diagnostic Procedure

Step	Inspection		Action
1	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 1.5, SKYACTIV-G 2.0, SKYACTIV-G 2.5].) • 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.
1		No	Repair or replace the connector.
2	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.
2		No	Replace the instrument cluster. (See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)
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.
3		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.
4		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 module. (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.
5		No	Replace the vehicle control module. (See VEHICLE CONTROL MODULE (V/C-MODULE) REMOVAL/INSTALLATION [MAZDA RADAR CRUISE CONTROL (MRCC) SYSTEM].)
