DTC C1A67:54 [VEHICLE CONTROL MODULE (V/C-MODULE)]

id0102i0001600

System malfunction location	Radar sensor aiming adjustment not implemented
Detection condition	•  Radar sensor aiming adjustment is not performed
Fail-safe	•  Inhibits the mazda radar cruise control (MRCC) system control •  Inhibits the smart brake support (SBS) system control •  Inhibits the distance recognition support system (DRSS) control
Possible cause	•  Radar sensor aiming adjustment not performed •  Radar unit which was used on a different vehicle is installed. Note •  If the ignition is switched off when an error occurs during the aiming adjustment command execution, a DTC is detected indicating that the aiming adjustment was not performed. •  If the ignition is switched OFF in the middle of aiming, the radar unit may detect a DTC even if the radar unit power supply voltage is stable.
System wiring diagram	•  Not applicable

Diagnostic Procedure

Step	Inspection		Action
1	PERFORM THE RADAR SENSOR AIMING ADJUSTMENT •  Perform the radar sensor aiming adjustment. (See RADAR SENSOR AIMING [MAZDA RADAR CRUISE CONTROL (MRCC) SYSTEM].) •  Was the aiming adjustment completed?	Yes	Go to the step 3.
		No	If error code is displayed •  Inspect/repair the error cause according to the error code and perform the radar unit aiming adjustment again. (See RADAR SENSOR AIMING [MAZDA RADAR CRUISE CONTROL (MRCC) SYSTEM].) •  Go to the step 3. If the M-MDS screen suddenly closes during aiming •  Go to the next step. (Radar unit power supply circuit and ground malfunction can be considered)
2	INSPECT CIRCUITS OF RADAR UNIT POWER SUPPLY SYSTEM AND GROUND •  Inspect the circuits of the radar unit power supply system and the ground. ―  Open circuit, short circuit ―  Poor connection of ground point •  Are the circuits and ground point normal?	Yes	Perform the aiming adjustment and then go to the next step. (See RADAR SENSOR AIMING [MAZDA RADAR CRUISE CONTROL (MRCC) SYSTEM].)
		No	After repairing the malfunction, perform the aiming adjustment and then go to the next step. (See RADAR SENSOR AIMING [MAZDA RADAR CRUISE CONTROL (MRCC) SYSTEM].)
3	VERIFY THAT REPAIRS HAVE BEEN COMPLETED •  Clear vehicle control module (V/C-module) DTCs using the M-MDS. (See CLEARING DTC.) •  Switch the ignition ON (engine on). •  Drive the vehicle at 40 km/h (25 mph) or more for 3 min or more. •  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.
4	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.
