id0102c4832700

DTC P0563

Battery voltage high input
DETECTION CONDITION
•  The PCM monitors the battery voltage. If the battery voltage is more than 16 V, the PCM determines that there is a malfunction in the battery charging system.
POSSIBLE CAUSE
•  Generator malfunction
•  Battery malfunction
•  Connector or terminal malfunction
•  Open circuit in wiring harness between generator terminal S and battery positive terminal
•  Related wiring harness malfunction
•  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 SERVICE INFORMATION AVAILABILITY
•  Verify related service information availability.
•  Is any related service information available?
Yes
Perform repair or diagnosis according to the available service information.
•  If the vehicle is not repaired, go to the next step.
No
Go to the next step.
3
VERIFY CURRENT SIGNAL STATUS: IS CONCERN INTERMITTENT OR CONSTANT?
•  Connect the M-MDS to the DLC-2.
•  Clear the DTC from the PCM memory using the M-MDS.
•  Start the engine.
•  Is the same DTC present?
Yes
Go to the next step.
No
Intermittent concern exists.
Perform the “INTERMITTENT CONCERN TROUBLESHOOTING”.
(See INTERMITTENT CONCERN TROUBLESHOOTING [WL-C, WE-C].)
4
INSPECT GENERATOR TERMINAL FOR POOR INSTALLATION
•  Turn the engine switch off.
•  Inspect generator terminal B for looseness.
•  Is there any malfunction?
Yes
Connect generator terminal B correctly, then go to Step 10.
No
Go to the next step.
5
INSPECT GENERATOR
•  Inspect the generator.
•  Is there any malfunction?
Yes
Replace the generator, then go to Step 10.
(See GENERATOR REMOVAL/INSTALLATION [WLT-1, WLT-2, WL-3, WL-C, WE-C].)
No
Go to the next step.
6
INSPECT BATTERY POSITIVE TERMINAL FOR POOR INSTALLATION
•  Turn the engine switch off.
•  Inspect the battery positive terminal for looseness.
•  Is there any malfunction?
Yes
Connect the battery positive terminal correctly, then go to Step 10.
No
Go to the next step.
7
INSPECT BATTERY
•  Inspect the battery.
•  Is there any malfunction?
Yes
Replace the battery, then go to Step 10.
(See BATTERY REMOVAL/INSTALLATION [WLT-1, WLT-2, WL-3, WL-C, WE-C].)
No
Go to the next step.
8
INSPECT PCM CONNECTOR FOR POOR CONNECTION
•  Turn the engine switch off.
•  Inspect for poor connection (such as damaged/pulled-out terminals, corrosion).
•  Is there any malfunction?
Yes
Repair or replace the terminal, then go to Step 6.
No
Go to the next step.
9
INSPECT GENERATOR CIRCUIT SHORT CIRCUIT
•  Inspect for continuity between generator terminal S (wiring harness-side) and battery plus terminal.
•  Is there continuity?
Yes
Go to the next step.
No
Repair or replace the wiring harness for short, then go to the next step.
10
VERIFY TROUBLESHOOTING OF DTC P0563 COMPLETED
•  Turn the engine switch off.
•  Make sure to reconnect all disconnected connectors.
•  Turn the engine switch to the ON position (Engine off).
•  Clear the DTC from the memory using the M-MDS.
•  Run the vehicle under the FREEZE FRAME DATA stored condition.
•  Is the same DTC present?
Yes
Replace the PCM, then go to the next step.
(See PCM REMOVAL/INSTALLATION [WL-C, WE-C].)
(See PCM REMOVAL/INSTALLATION (U.K. Specs.) [WL-C, WE-C].)
No
Go to the next step.
11
VERIFY AFTER REPAIR PROCEDURE
•  Perform the “After Repair Procedure“.
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
(See DTC TABLE [WL-C, WE-C (Australian, European (L.H.D. U.K.) specs.)].)
No
DTC troubleshooting completed.
