Warning

<<High voltage>>

• Always observe the following thoroughly to ensure safety when inspecting or removing/installing parts in the motor compartment. Otherwise, the high voltage circuit may operate on the vehicle regardless of whether or not the main power is switched OFF or ON (READY off or on). If this occurs, it could cause electrical shock and result in serious injury or, in the worst case, death.

― Do not select high voltage battery cooling on center display after EV system stops

― Do not open/close doors frequently with main power switched OFF

― Do not perform normal charging or quick charging

― Switch to connected vehicle maintenance mode (MyMazda App connected vehicle)

― Cancel climate control timer

― Operate center display and turn off battery heater operation

Warning

• The cooling fan may suddenly start operating regardless of the main power switch position. Keep hands and tools away from the cooling fan even if the cooling fan is not operating to prevent injury, or damage to the cooling fan. When servicing the cooling fan or parts near the cooling fan, ensure the following.

― Do not perform normal charging or quick charging

― Do not select high voltage battery cooling on center display after EV system stops

― Do not open/close doors frequently with main power switched OFF

― Switch to connected vehicle maintenance mode (MyMazda App connected vehicle)

― Cancel climate control timer

― Operate center display and turn off battery heater operation

Note

• Due to environmental effects, the system behavior may differ from the driver’s intentions even though the vehicle has no malfunction. To perform symptom troubleshooting, an understanding of the applicable system from the service highlights/technical guide is required. For details on the control conditions of the system, refer to the [LANE-KEEP ASSIST SYSTEM] operation in the service highlights/technical guide.

Diagnostic Procedure

Step

Inspection

Results

Action

1

VERIFY ALL SYSTEM DTCs

•  Perform the DTC inspection.
(See DTC INSPECTION.)

•  Are any DTCs displayed?

Yes

Repair the malfunctioning location according to the applicable DTC troubleshooting.

No

Go to the next step.

2

VERIFY MALFUNCTION SYMPTOM

•  Does the applicable malfunction occur only at nighttime?

Yes

Go to the next step.

No

Go to Step 4.

3

VERIFY FRONT COMBINATION LIGHT CONDITION

•  Visually verify the applicable part.

•  Do any of the following apply?

―  Front combination light malfunction

―  Front combination light optical axis deviation

―  Dirt on area around front combination light

Yes

Repair or replace the malfunctioning location and perform the repair completion verification.

(See FRONT COMBINATION LIGHT REMOVAL/INSTALLATION.)

No

Go to the next step.

4

VERIFY CONDITION AROUND FORWARD SENSING CAMERA (FSC)

•  Visually verify the applicable part.

•  Are there any water droplets, condensation, or dirt?

Yes

Repair or replace the malfunctioning location and perform the repair completion verification.

No

Go to the next step.

5

VERIFY PERSONALIZATION FEATURES SETTING

•  Verify the [Lane-keep Assist System] using the personalization features.
(Refer to the [PERSONALIZATION FEATURES] in the workshop manual)

•  Has the [Lane-keep Assist System] turned [Disable]?

Yes

Complete the symptom troubleshooting. (Explain the system operation conditions to the customer.)

No

Go to the next step.

Repair completion verification

VERIFY THAT VEHICLE IS REPAIRED

•  Install/connect the part removed/disconnected during the troubleshooting procedure.

•  Has the malfunction symptom been eliminated?

Yes

Complete the symptom troubleshooting. (Explain contents of repair to customer)

No

Refer to the controller area network (CAN) malfunction diagnosis flow to inspect for a CAN communication error.

(See CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW [L.H.D. (E)].)

(See CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW [R.H.D.].)

If the CAN communication is normal, perform the diagnosis from Step 1.

•  If the malfunction is not resolved, replace the forward sensing camera (FSC).
(See FORWARD SENSING CAMERA (FSC) REMOVAL/INSTALLATION.)
