Ski-Doo P1562 / P1563 Fault Code (800 E-TEC) — Diagnosis Guide
Diagnostic guide for Ski-Doo P1562 and P1563 fault codes. Explains how stator wiring damage and flywheel failure cause voltage faults and how to properly inspect the system.
Manual content
Overview
This guide explains the root cause of P1562 and P1563 fault codes on Ski-Doo 800 E-TEC engines. The issue is typically caused by damage to stator output wires due to flywheel inner ring failure, leading to incorrect voltage readings detected by BUDS.
Ski-Doo P1562 / P1563 Fault Code Diagnosis
This guide explains how to diagnose P1562 and P1563 fault codes on Ski-Doo 800 E-TEC engines and identifies the root cause of these voltage-related issues.
Fault Code Meaning
- P1562 — High voltage fault
- P1563 — Low voltage fault
These codes are typically detected through BUDS diagnostics and indicate abnormal voltage readings in the system.
Root Cause of the Problem
Recent investigations have shown that these faults are commonly caused by damage to the stator output wires.
The damage occurs when the flywheel inner steel ring begins to break apart or move out of position.
- Inner flywheel ring may crack or separate
- Loose ring can move and contact stator wiring
- This causes damage to stator output leads
Why This Causes Voltage Errors
When stator wiring is damaged, the electrical output becomes unstable. This leads to incorrect voltage readings, which are interpreted by the ECU as:
- Over-voltage (P1562)
- Under-voltage (P1563)
Even though the fault appears electrical, the root cause is mechanical.
Inspection Procedure
- Remove and inspect the flywheel
- Check inner steel ring for cracks or movement
- Inspect stator wiring for damage or wear
- Look for signs of contact between flywheel and wiring
Visual Indicators
- Damaged stator wires
- Loose or broken flywheel inner ring
- Burn marks or physical wear on wiring
Important Note
Do not replace electrical components before confirming mechanical integrity of the flywheel. Misdiagnosis can lead to unnecessary repairs.
Conclusion
P1562 and P1563 faults are often caused by mechanical damage affecting the stator wiring. Proper inspection of the flywheel and stator assembly is essential for accurate diagnosis.
