DTC P0562

BHE010200500W03

DTC P0562 | System voltage low (KAM)
--- | ---
DETECTION CONDITION | • The PCM monitors the battery voltage when the engine is running. If the voltage is less than 2.5 V, the PCM determines that the system voltage is low. Diagnostic support note • This is a continuous monitor (CCM). • The MIL illuminates if the PCM detects the above malfunction condition in the first drive cycle. • PENDING CODE is available if the PCM detects the above malfunction condition. • FREEZE FRAME DATA is available. • The DTC is stored in the PCM memory.
POSSIBLE CAUSE | • Battery malfunction • Connector or terminal malfunction • Open circuit in wiring harness between battery positive terminal and PCM terminal 5J • Short to GND in wiring harness between battery positive terminal and PCM terminal 5J • Meltdown fuse • PCM malfunction

Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | VERIFY FREEZE FRAME DATA HAS BEEN RECORDED • Has FREEZE FRAME DATA been recorded? | 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 repair 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 • Inspect the fuse. • Is there any malfunction? | Yes | Replace the fuse, then go to Step 9.
No | Go to the next step.
4 | INSPECT BATTERY POSITIVE TERMINAL FOR POOR INSTALLATION • Turn the ignition switch off. • Inspect for looseness of the battery positive terminal. • Is there any malfunction? | Yes | Connect the battery positive terminal correctly, then go to Step 9.
No | Go to the next step.
5 | INSPECT BATTERY CIRCUIT FOR SHORT TO GND • Turn the ignition switch off. • Inspect for continuity between battery positive terminal (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 9.
No | Go to the next step.
6 | INSPECT BATTERY • Inspect the battery. (See BATTERY INSPECTION.) • Is there any malfunction? | Yes | Replace the battery, then go to Step 9. (See BATTERY REMOVAL/INSTALLATION.)
No | Go to the next step.
7 | INSPECT PCM CONNECTOR FOR POOR CONNECTION • Turn the ignition switch off. • Disconnect the PCM connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Is there any malfunction? | Yes | Repair or replace the terminal, then go to Step 9.
No | Go to the next step.
8 | INSPECT BATTERY CIRCUIT FOR OPEN CIRCUIT • Turn the ignition switch off. • Inspect for continuity between battery positive terminal (wiring harness-side) and PCM terminal 5J (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 the next step.
9 | VERIFY TROUBLESHOOTING OF DTC P0562 COMPLETED • Make sure to reconnect all disconnected connectors. • Clear the DTC from the PCM memory using the WDS or equivalent. • Start the engine. • Is the same DTC present? | Yes | Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION.)
No | Go to the next step.
10 | VERIFY AFTER REPAIR PROCEDURE • Perform the "AFTER REPAIR PROCEDURE". (See AFTER REPAIR PROCEDURE.) • Are any DTCs present? | Yes | Go to the applicable DTC inspection. (See DTC TABLE.)
No | DTC troubleshooting completed.
