DTC P0562 [MZR-CD (RF Turbo)]

id0102f1832600

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. Diagnostic support note • The MIL illuminates if the PCM detects the above malfunction condition in the first drive cycle. • FREEZE FRAME DATA is available. • The DTC is stored in the PCM memory.
POSSIBLE CAUSE | • Drive belt condition • Generator malfunction • Open circuit in wiring harness between generator terminal D and PCM terminal 9 • Open circuit in wiring harness between generator terminal P and PCM terminal 77 • Short to ground in wiring harness between generator terminal D and PCM terminal 9 • Short to ground in wiring harness between generator terminal P and PCM terminal 77 • Poor connection of connector at 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 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 | VERIFY CURRENT SIGNAL STATUS: IS CONCERN INTERMITTENT OR CONSTANT? • Connect the WDS or equivalent to the DLC-2. • Clear the DTC from the PCM memory using the WDS or equivalent. • 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 [MZR-CD (RF Turbo)].)
4 | INSPECT DRIVE BELT CONDITION • Verify that drive belt auto tensioner indicator mark does not exceed limit. • Is drive belt normal? | Yes | Go to the next step.
No | Replace and/or adjust drive belt, then go to Step 9. (See DRIVE BELT REPLACEMENT [MZR-CD (RF Turbo)].)
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. (See GENERATOR INSPECTION [MZR-CD (RF Turbo)].) • Is there any malfunction? | Yes | Replace the generator, then go to Step 9. (See GENERATOR REMOVAL/INSTALLATION [MZR-CD (RF Turbo)].)
No | Go to the next step.
7 | INSPECT GENERATOR CIRCUIT FOR OPEN CIRCUIT • Inspect for continuity between the following terminal: - Generator terminal D (wiring harness-side) and PCM terminal 9 - Generator terminal P (wiring harness-side) and PCM terminal 77 • Are there continuity? | Yes | Go to the next step.
No | Repair or replace the wiring harness for open, then go to Step 9.
8 | INSPECT GENERATOR CIRCUIT FOR SHORT TO GROUND • Inspect for continuity between the following terminal: - Generator terminal D (wiring harness-side) and PCM terminal 9 - Generator terminal P (wiring harness-side) and PCM terminal 77 • Are there continuity? | Yes | Go to the next step.
No | Repair or replace the wiring harness for short, 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 [MZR-CD (RF Turbo)].)
No | Go to the next step.
10 | VERIFY AFTER REPAIR PROCEDURE • Perform the Repair Verification Drive Mode. (See OBD DRIVE MODE [MZR-CD (RF Turbo)].) • Are any DTCs present? | Yes | Go to the applicable DTC inspection. (See DTC TABLE [MZR-CD (RF Turbo)].)
No | DTC troubleshooting completed.
