DESCRIPTION
Some vehicles may experience the opening sequence of the instrument cluster is not displayed after IG-ON.
NOTE: Opening sequence of the instrument cluster refers to the display that occurs immediately after ignition is turned
on. The vehicle model's logo is shown on the instrument cluster's LCD screen before transitioning to the speedometer
display. The sequence also swings the analog meter needle to its maximum.
This concern is caused by improper control software of the BCM. To eliminate this concern, the control software of the
BCM control module has been modified.
Customers having this concern should have their vehicle repaired using the following repair procedure.
NOTE: CSSU regulation compliance: This Service Information provides the software modification and the software
information according to United Nations Regulation on Cybersecurity (CS) and Software Updates (SU).

REPAIR PROCEDURE
1. Verify the customer concern.
2. Reprogram the BCM using the Mazda Diagnostic And Repair Software (MDARS). Refer to MDARS ECU
REPROGRAMMING PROCEDURE.

• Reprogramming is not necessary if current calibration file name in the ECU FILENAME screen is the same as
shown in Calibration Files Information or with later suffix.
• The parameter “Battery State of Charge (SOC)” is reset during PCM reprogramming procedure.
• Since the SOC value is necessary when performing “Battery condition initialization setting” after PCM
reprogramming to decide whether battery charging is necessary or not, measure and record the PID “BATT_SOC”
first by using M-MDS Data logger function before reprogramming the PCM.
• After the reprogramming, pending DTC P2610:00 [PCM] may be stored without MIL illumination. Since this DTC
may turn to a current DTC depending on operations after the reprogramming, clear DTC after all repair work is
done.
3. After BCM reprogramming, conduct the battery condition initial setting (i-stop setting) according to the instructions in
MGSS BATTERY CONDITION INITIALIZATION SETTING (i-stop SETTING)
4. Clear the DTC and turn the ignition off and get out of the car.
5. Close and lock the door then wait ten minutes or more.
6. Verify the repair by starting the engine and confirming there is no CHECK ENGINE light ON or abnormal warning
lights present.
NOTE: If any DTCs should remain after deleting DTC, diagnose the DTCs according to the appropriate Troubleshooting
section on MGSS.
