id050218824700

DTC P0884:00

Battery voltage low

DETECTION CONDITION

•  The PCM detects that battery voltage is less than 8.25 V for 10 s when the following conditions are met.

―  ATF temperature: less than 90 °C {194 °F}

―  Engine speed: more than 500 rpm

Diagnostic support note:

•  The MIL illuminates if the PCM detects the above malfunction conditions during the first drive cycle.

•  PENDING CODE is available.

•  FREEZE FRAME DATA is available.

•  The AT 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

•  Melt down ENG main 40A fuse

•  Main relay malfunction

•  Main relay connector or terminal malfunction

•  Short to GND in wiring harness between battery positive terminal and PCM terminal 1BG

•  Open circuit in wiring harness between battery positive terminal and PCM terminal 1BG

•  PCM connector or terminal malfunction

•  PCM malfunction

DTC P0884:00	Battery voltage low
DETECTION CONDITION	• The PCM detects that battery voltage is less than 8.25 V for 10 s when the following conditions are met. ― ATF temperature: less than 90 °C {194 °F} ― Engine speed: more than 500 rpm Diagnostic support note: • The MIL illuminates if the PCM detects the above malfunction conditions during the first drive cycle. • PENDING CODE is available. • FREEZE FRAME DATA is available. • The AT 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	• Melt down ENG main 40A fuse • Main relay malfunction • Main relay connector or terminal malfunction • Short to GND in wiring harness between battery positive terminal and PCM terminal 1BG • Open circuit in wiring harness between battery positive terminal and PCM terminal 1BG • 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.
1		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.
2		No	Go to the next step.
3	INSPECT ENG MAIN 40A FUSE • Switch the ignition off. • Disconnect the battery negative cable. • Inspect the ENG main 40A fuse for proper installation and failure. • Is the ENG main 40A fuse normal?	Yes	Go to the next step.
3		No	• If the ENG main 40A fuse is not installed correctly, install it correctly. Then go to Step 10. • If the ENG main 40A fuse has melted down, replace it. Then go to Step 10.
4	INSPECT AT MAIN RELAY • Remove the main relay. • Inspect the main relay. (See RELAY INSPECTION.) • Is the main relay normal?	Yes	Go to the next step.
4		No	Replace the main relay, then go to Step 10.
5	INSPECT AT 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.
5		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 D (wiring harness-side) and body GND ― Main relay terminal C (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.
6		No	Go to the next step.
7	INSPECT POWER SUPPLY CIRCUIT FOR OPEN CIRCUIT • Inspect for continuity between main relay terminal D (wiring harness-side) and battery positive terminal (wiring harness-side). • Is there continuity?	Yes	Go to the next step.
7		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.
8		No	Go to the next step.
9	INSPECT POWER SUPPLY CIRCUIT FOR OPEN CIRCUIT • Inspect for continuity between main relay terminal C (wiring harness-side) and PCM terminal 1BG (wiring harness-side). • Is there continuity?	Yes	Go to the next step.
9		No	Repair or replace the wiring harness for a possible open circuit, then go to next step.
10	VERIFY TROUBLESHOOTING OF DTC P0884:00 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. (See PCM REMOVAL/INSTALLATION [FN4A-EL].)
10		No	Go to the next step.
11	VERIFY NO DTC HAS BEEN PRESENTED • Perform the “Reading DTCs Procedure”. (See ON-BOARD DIAGNOSTIC SYSTEM DTC INSPECTION [FN4A-EL].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See ON-BOARD DIAGNOSTIC SYSTEM DTC TABLE [FN4A-EL].)
11		No	DTC troubleshooting completed.
