DTC P0563:00 [MZR-CD 2.2]

id0102f3156300

DTC P0563:00

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.

Diagnostic support note

•  The MIL illuminates if the PCM detects the above malfunction condition in first drive cycle.

•  PENDING CODE is available if the PCM detects the above malfunction condition during the first drive cycle.

•  FREEZE FRAME DATA (mode2) and snapshot data are available.

•  The DTC is stored in the PCM memory.

POSSIBLE CAUSE

•  Generator connector or terminal malfunction

•  Short to power supply in wiring harness between generator terminal D and PCM terminal 1BD

•  PCM connector or terminal malfunction

•  Generator malfunction

•  PCM malfunction

Diagnostic procedure

STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA (MODE2) OR SNAPSHOT DATA HAVE BEEN RECORDED • Have FREEZE FRAME DATA (mode2) or snapshot data been recorded?	Yes	Go to the next step.
1		No	Record the FREEZE FRAME DATA (mode2) and snapshot 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.
2		No	Go to the next step.
3	VERIFY CURRENT SIGNAL STATUS: IS CONCERN INTERMITTENT OR CONSTANT? • Clear the DTC from the PCM memory using the M-MDS. (See AFTER REPAIR PROCEDURE [MZR-CD 2.2].) • Start the engine. • Perform the DTC Reading Procedure. (See ON-BOARD DIAGNOSTIC TEST [MZR-CD 2.2].) • Is the same DTC present?	Yes	Go to the next step.
3		No	Intermittent concern exists. Perform the “INTERMITTENT CONCERN TROUBLESHOOTING”. (See INTERMITTENT CONCERN TROUBLESHOOTING [MZR-CD 2.2].)
4	INSPECT GENERATOR CONNECTOR FOR POOR CONNECTION • Switch the ignition to off. • Disconnect the generator 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 8.
4		No	Go to the next step.
5	INSPECT GENERATOR CONTROL TERMINAL FOR SHORT TO POWER SUPPLY • Switch the ignition to off. (Engine off) • Measure the voltage between generator terminal D (wiring harness-side) and body ground. • Is the voltage B+?	Yes	Repair or replace the wiring harness for a possible short to power supply, then go to Step 8.
5		No	Go to the next step.
6	INSPECT PCM CONNECTOR FOR POOR CONNECTION • Switch the ignition to 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 8.
6		No	Go to the next step.
7	INSPECT GENERATOR • Inspect the generator. (See GENERATOR INSPECTION [MZR-CD 2.2].) • Is there any malfunction?	Yes	Replace the generator, then go to the next step. (See GENERATOR REMOVAL/INSTALLATION [MZR-CD 2.2].)
7		No	Go to the next step.
8	VERIFY TROUBLESHOOTING OF DTC P0563:00 COMPLETED • Make sure to reconnect all disconnected connectors. • Clear the DTC from the PCM memory using the M-MDS. (See AFTER REPAIR PROCEDURE [MZR-CD 2.2].) • Start the engine. • Perform the DTC Reading Procedure. (See ON-BOARD DIAGNOSTIC TEST [MZR-CD 2.2].) • Is the same DTC present?	Yes	Repeat the inspection from Step 1. • If the malfunction recurs, replace the PCM. (See PCM REMOVAL/INSTALLATION [MZR-CD 2.2].) Go to the next step.
8		No	Go to the next step.
9	VERIFY AFTER REPAIR PROCEDURE • Perform the “AFTER REPAIR PROCEDURE”. (See AFTER REPAIR PROCEDURE [MZR-CD 2.2].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [MZR-CD 2.2].)
9		No	DTC troubleshooting completed.
