id0102c4832600

DTC P0562

Battery voltage low input
DETECTION CONDITION
•  The PCM monitors the battery voltage. If the battery voltage is less than 8 V, the PCM determines that there is a malfunction in the battery and the battery signal system.
POSSIBLE CAUSE
•  Drive belt condition
•  Generator malfunction
•  Open circuit in wiring harness between generator terminal S and battery positive terminal
•  Short to ground in wiring harness between generator terminal S and battery positive terminal
•  Poor connection of connector at battery positive terminal
•  Poor battery positive terminal
•  Terminal 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 DRIVE BELT CONDITION
•  Verify that the drive belt auto tensioner indicator mark does not exceed the limit.
•  Is the drive belt normal?
Yes
Go to the next step.
No
Replace and/or the adjust drive belt, then go to Step 9.
(See DRIVE BELT ADJUSTMENT [WL-C, WE-C].)
5
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 9.
No
Go to the next step.
6
INSPECT GENERATOR
•  Inspect the generator.
•  Is there any malfunction?
Yes
Replace the generator, then go to Step 9.
(See GENERATOR REMOVAL/INSTALLATION [WLT-1, WLT-2, WL-3, WL-C, WE-C].)
No
Go to the next step.
7
INSPECT GENERATOR CIRCUIT FOR OPEN CIRCUIT
•  Inspect for continuity between generator terminal S (wiring harness-side) and battery positive terminal (wiring harness-side).
•  Is there any continuity?
Yes
Go to the next step.
No
Repair or replace the wiring harness for an open circuit, then go to Step 9.
8
INSPECT GENERATOR CIRCUIT FOR SHORT TO GROUND
•  Inspect for continuity between generator terminal S (wiring harness-side) and body ground.
•  Is there any continuity?
Yes
Go to the next step.
No
Repair or replace the wiring harness for a short 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 M-MDS.
•  Start the engine.
•  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.
10
VERIFY AFTER REPAIR PROCEDURE
•  Perform the Repair Verification Drive Mode.
•  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.
