Go to the next step.

2

VERIFY DC-DC CONVERTER (Mazda M Hybrid) DTC

•  Perform the DTC inspection for the DC-DC converter (Mazda M Hybrid).
(See DTC INSPECTION.)

•  Is DTC U3000:49 displayed?

Yes

Repair the malfunctioning location according to the applicable DTC troubleshooting.

(See DTC U3000:49 [DC-DC CONVERTER (Mazda M Hybrid)].)

No

Go to the next step.

3

VERIFY WHETHER MALFUNCTION IS PRESENT OR PAST

•  Perform the DTC inspection for the Mazda M Hybrid battery.
(See DTC INSPECTION.)

•  Is DTC P1B06:00 a present malfunction?

Yes

Go to Step 5.

No

Go to the next step.

4

PERFORM REPLICATION TEST

•  Switch the ignition off.

•  Switch the ignition ON (engine off or on) and wait for 5 s or more.

•  Perform the DTC inspection for the Mazda M Hybrid battery.
(See DTC INSPECTION.)

•  Is DTC P1B06:00 a present malfunction?

Yes

Go to the next step.

No

The system is normal. (Explain to the customer that a DTC may be displayed when large vibration is applied in the upward/downward direction such as when driving over an uneven road.)

Go to repair completion verification 2.

5

INSPECT Mazda M Hybrid BATTERY POWER SUPPLY CIRCUIT

•  Inspect the applicable circuit.
(See CIRCUIT INSPECTION.)

•  Is the circuit normal?

Yes

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 [(E)].)

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

•  If the malfunction recurs, replace the Mazda M Hybrid battery and perform the repair completion verification 2.
(See Mazda M Hybrid BATTERY REMOVAL/INSTALLATION.)

No

Repair or replace the malfunctioning location and perform the repair completion verification 1.

INSPECT Mazda M Hybrid BATTERY FOR MALFUNCTION DEPENDING ON REPEATABILITY

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

•  Clear the DTC recorded in the memory.
(See CLEARING DTC.)

•  Perform the DTC inspection for the Mazda M Hybrid battery.
(See DTC INSPECTION.)

•  Is the same Pending DTC present?

Yes

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 [(E)].)

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

•  If the malfunction recurs, replace the Mazda M Hybrid battery and perform the repair completion verification.
(See Mazda M Hybrid BATTERY REMOVAL/INSTALLATION.)

No

Go to the next step.
