REPAIR PROCEDURE
1. Verify customer concern.
2. Verify that there is no external damage to the radar sensor, or impact around the radar sensor causing the
radar axis deviation.
3. Reboot the IDS to clear memory before reprogramming.
4. Using IDS 90.05 or later software, reprogram the Vehicle Control Module (VCM) to the latest calibration following the “Module Reprogramming” procedure.
NOTE:
•

Always update the IDS tool first, then follow on-screen instructions to download the needed calibration file for Vehicle Control Module (VCM) reprogramming.
• It is not necessary to remove any fuses or relays during VCM reprogramming when the IDS
screen prompts you to do so. You may accidentally stop power to one of the VCM terminals and
cause the VCM to be blanked, or you may receive error messages during the IDS reprogramming procedure.
• IDS shows the calibration part numbers after programming the VCM.
• Please be aware that VCM calibration part numbers and file names listed in any Service Bulletin
may change due to future releases of IDS software, and additional revisions made to those calibrations for service related concerns.
• When reprogramming a VCM, IDS will always display the “latest” calibration P/N available for
that vehicle. If any calibration has been revised/updated to contain new information for a new
service concern/issue, it will also contain all previously released calibrations.
• When performing this procedure, we recommend using the “Power Supply” mode in the
GR8 Battery Management System to keep the vehicle battery up to capacity. If a different
charger is used, make sure it does not exceed 20 AMPS. If it exceeds 20 AMPS, it could
damage the VCM.
a. Select “Module Reprogramming”, then select “SBS/MRCC”.

NOTE: The menu “SBS/MRCC” appears regardless of the equipment of MRCC System. For vehicles
without the MRCC System, do not click this menu.

b. Either of the following screens (Figure 1 or 2) is displayed.
- If the Figure 1 is displayed, the VCM is before the latest calibration. Click “YES” and follow the MMDS instructions to reprogram the VCM.
- If the Figure 2 is displayed, the VCM is already the latest calibration. This Service Information does
not apply and refer to Workshop Manual for troubleshooting and repair.

c.

Figure 2: Not subject for VCM reprogramming

After reprogramming, close the session. Then, open a new session and go to the “Log Viewer” screen.
The programmed file name is displayed as shown in figure below. If the last two letters are “44”, the
reprogramming has been successfully completed.

NOTE:
•

•

In some cases, the ABS warning light may illuminate and the engine will not shut off by onepress of the engine start/stop button. To correct this concern, disconnect the ABS/DSC 30A fuse
for 10 seconds.
After reprogramming, communication error related DTCs may be stored. This is normal operation. Delete these DTCs.

5. Perform the radar sensor aiming adjustment. Refer to MS3 online or Workshop Manual (section 01-20
RADAR SENSOR AIMING [MAZDA RADAR CRUISE CONTROL (MRCC) SYSTEM]).
6. After performing the VCM reprogramming and the radar sensor aiming adjustment, verify the repair by starting the engine and making sure there are no MIL illumination or abnormal warning lights present.
NOTE:
•
•
•

If DTC C1A67:78 is stored again after performing DTC erase, replace the radar sensor.
If any other DTCs should remain after performing DTC erase, diagnose the DTCs according to
the appropriate Troubleshooting section of the Workshop Manual.
After VCM reprogramming, it is no longer necessary to road test the vehicle to “relearn” KAM
(Keep Alive Memory).

7. Verify repair.
