DTC P0884:00

Battery voltage low

DETECTION CONDITION
•  The input voltage from battery is 8.25 V or more for 10 s when the engine speed is 500 rpm or more.
Diagnostic support note:
•  The check engine light illuminates if the PCM detects the above malfunction conditions during the first drive cycle.
•  PENDING CODE is available.
•  FREEZE FRAME DATA is available.
•  The automatic transaxle warning light illuminates if the PCM detects the above malfunction conditions during the first drive cycle.
•  The DTC is stored in the PCM memory.
POSSIBLE CAUSE
•  Blown fuse
•  Main relay malfunction
•  Main relay connector or terminal malfunction
•  Short to GND in wiring harness between battery positive terminal and PCM terminal 1BJ
•  Open circuit in wiring harness between battery positive terminal and PCM terminal 1BJ
•  PCM connector or terminal malfunction
•  PCM malfunction

Diagnostic procedure

STEP

INSPECTION

ACTION

1
VERIFY FREEZE FRAME DATA HAS BEEN RECORDED
•  Has the FREEZE FRAME DATA been recorded on the repair order?
Yes
Go to the next step.
No
Record the FREEZE FRAME DATA on the repair order, then go to the next step.
2
VERIFY RELATED REPAIR INFORMATION AVAILABILITY
•  Verify related Service Information availability.
•  Is any related repair information available?
Yes
Perform repair or diagnosis according to the available repair information.
•  If the vehicle is not repaired, go to the next step.
No
Go to the next step.
3
INSPECT FUSE
•  Switch the ignition off.
•  Disconnect the battery negative cable.
•  Inspect the MAIN 200A, ENG. MAIN 40A and ENGINE1 15A fuse for proper installation and failure.
•  Are these fuses normal?
Yes
Go to the next step.
No
•  If a fuse is not installed correctly, install it correctly. Then go to Step 10.
•  If a fuse has blown, replace it. Then go to Step 10.
4
INSPECT MAIN RELAY
•  Remove the main relay.
•  Inspect the main relay.
•  Is the main relay normal?
Yes
Go to the next step.
No
Replace the main relay, then go to Step 10.
5
INSPECT MAIN RELAY CONNECTOR FOR POOR CONNECTION
•  Inspect for poor connection (such as damaged/pulled-out pins, and corrosion).
•  Is there any malfunction?
Yes
Repair or replace the terminal, then go to Step 10.
No
Go to the next step.
6
INSPECT POWER SUPPLY CIRCUIT FOR SHORT TO GND
•  Disconnect the battery positive cable.
•  Inspect for continuity between the following circuits:
―  Main relay terminal C (wiring harness-side) and body GND
―  Main relay terminal D (wiring harness-side) and body GND
•  Is there continuity?
Yes
Repair or replace the wiring harness for a possible short to GND, then go to Step 10.
No
Go to the next step.
7
INSPECT POWER SUPPLY CIRCUIT FOR OPEN CIRCUIT
•  Inspect for continuity between main relay terminal C (wiring harness-side) and battery positive terminal (wiring harness-side).
•  Is there continuity?
Yes
Go to the next step.
No
Repair or replace the wiring harness for a possible open circuit, then go to Step 10.
8
INSPECT PCM CONNECTOR FOR POOR CONNECTION
•  Disconnect the PCM connector.
•  Inspect for poor connection (such as damaged/pulled-out pins, and corrosion).
•  Is there any malfunction?
Yes
Repair or replace the terminal, then go to Step 10.
No
Go to the next step.
9
INSPECT POWER SUPPLY CIRCUIT FOR OPEN CIRCUIT
•  Inspect for continuity between main relay terminal D (wiring harness-side) and PCM terminal 1BJ (wiring harness-side).
•  Is there continuity?
Yes
Go to the next step.
No
Repair or replace the wiring harness for a possible open circuit, then go to next step.
10
VERIFY DTC TROUBLESHOOTING COMPLETED
•  Make sure to reconnect all the disconnected connectors.
•  Clear the DTC from the PCM memory using the M-MDS.
•  Perform the following procedure to ensure that the DTC has been resolved:
1.  Start the engine.
2.  Idle the engine for 10 s or more.
•  Is the same DTC present?
Yes
Replace the PCM, then go to the next step.
No
Go to the next step.
11
VERIFY NO DTCs ARE PRESENT
•  Perform the “Reading DTCs Procedure”.
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
No
DTC troubleshooting completed.
