Description

Mazda M Hybrid battery: Cell overcharge malfunction

Detection condition

Determination conditions

•  The voltage of the cell in the Mazda M Hybrid battery is more than 2.9 V.

Preconditions

•  Mazda M Hybrid battery is any of the following conditions (PID: BECM_STAT)

―  INITIAL

―  STANDBY

―  PRECHARGE

―  READY

•  The following DTCs are not detected:

―  P0B3C:00, P0B3D:11, P0B3D:13 and P0B3E:00

Malfunction determination period

•  0.5 s period

Drive cycle

•  1

Self test type

•  CMDTC self test, ODDTC self test

Sensor used

•  Mazda M Hybrid battery

Fail-safe function

•  Stops power supply from the Mazda M Hybrid battery and supplies power to the vehicle’s electrical devices (12 V power supply) from the 12 V battery.

•  Inhibits the i-stop control.

•  Inhibits the non-power generation control.

•  Inhibits regenerative braking by the integrated starter generator (ISG).

•  Inhibits motor assist control by the integrated starter generator (ISG).

Vehicle status when DTCs are output

•  If the vehicle continues to be driven while the DTC is detected, the 12 V battery will be depleted and the vehicle can no longer be driven.

•  Inhibits the i-stop control.

Possible cause

•  Integrated starter generator (ISG) malfunction

•  Mazda M Hybrid battery malfunction

―  Mazda M Hybrid battery cell deterioration

―  Decrease in temperature in Mazda M Hybrid battery

System Wiring Diagram

• Not applicable

Function Explanation (DTC Detection Outline)

• If the voltage of each cell (No.1—No.9) in the Mazda M Hybrid battery is more than 2.9 V for a continuous 0.5 s, the Mazda M Hybrid battery determines a malfunction and stores a DTC.

Repeatability Verification Procedure

1. Start the engine.

Go to the next step.

2

VERIFY DTCs

•  Perform the DTC inspection for the following modules.
(See DTC INSPECTION.)

―  PCM

―  Integrated starter generator (ISG)

•  Are any other of the following DTCs displayed as a present malfunction?

―  P0A7A:00

―  P1BC5:00

―  P1BC6:00

Yes

Repair the malfunctioning location according to the applicable DTC troubleshooting.

(See DTC P0A7A:00 [PCM (SKYACTIV-G (WITH Mazda M Hybrid))].)

(See DTC P0A7A:00 [PCM (SKYACTIV-X)].)

(See DTC P0A7A:00 OR P1BC5:00 [INTEGRATED STARTER GENERATOR (ISG)].)

(See DTC P1BC6:00 [INTEGRATED STARTER GENERATOR (ISG)].)

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 [(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 1.
(See Mazda M Hybrid BATTERY REMOVAL/INSTALLATION.)

Repair completion verification 1

VERIFY THAT VEHICLE IS REPAIRED

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

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

•  Start the engine.

•  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, then go to the next step.
(See Mazda M Hybrid BATTERY REMOVAL/INSTALLATION.)

No

Go to the next step.

Repair completion verification 2

VERIFY IF OTHER DTCs DISPLAYED

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

•  Are any other DTCs displayed?

Yes

Repair the malfunctioning location according to the applicable DTC troubleshooting.

No

DTC troubleshooting completed.
