| FMI | Description | Example Remedial Focus | |-----|-------------|------------------------| | | Data valid but above normal range | High pressure, temperature, or speed | | 1 | Data valid but below normal range | Low pressure, low voltage | | 2 | Data erratic, intermittent, or incorrect | Loose connection, damaged sensor | | 3 | Voltage above normal (shorted high) | Short to +BAT, wiring chafe | | 4 | Voltage below normal (shorted low) | Short to ground | | 5 | Current below normal (open circuit) | Broken wire, failed solenoid/valve coil | | 6 | Current above normal (grounded circuit) | Short inside component | | 8 | Abnormal frequency / period | Faulty speed sensor, tone ring damage | | 11 | Root cause not known (malfunction) | Generic failure, often requires swapping a known‑good component | | 31 | Not available or condition exists | Software‑related or missing data |
Troubleshooting Doosan Fault Code VPV00105: Causes, Symptoms, and Fixes
What is the of your Doosan machine (e.g., DX140, DX225, DX300)? Do you have a multimeter on hand to test the circuit? Are you noticing any other error codes alongside this one? Share public link
A loose connector at the sensor or the ECM. doosan fault code vpv00105 new
When this error code triggers on a machine like a Doosan DX140LC or DX180LC, the culprit falls into one of three electrical categories: 1. Sensor Unplugged or Disconnected
: The machine will bypass its pre-heating/glow-plug sequences.
Examine the wiring harness for signs of chafing, corrosion, or breaking. Ensure the connector is clean and securely plugged in. 3. Check for Voltage Errors | FMI | Description | Example Remedial Focus
Understanding the architecture of a VPV prefix code is vital for plant fitters, fleet managers, and heavy equipment mechanics operating modern Doosan DX-series platforms. Code Architecture: What VPV001-05 Means
Check for chafing, broken wires, or rodent damage to the harness leading to the sensor. 3. Examine the Sensor Connector
Check for signs of localized coolant leaks around the sensor body threads. 2. Inspect the Sensor Connector and Harness Share public link A loose connector at the
Inspect the plastic harness connector for unlatched clips, backing-out pins, or moisture intrusion. 2. Electrical Harness Testing
If the harness checks out completely, the internal thermistor (for coolant applications) or piezo-resistive bridge element (for hydraulic pilot pressure applications) has burnt out, creating an infinite resistance barrier that mimics a severed wire. Step-by-Step Diagnostic & Repair Strategy
🧑🔧 They can remotely access the machine’s telematics (CoreTMS) and often diagnose the code without a site visit.
Newer machines feature tight wiring routing. Over time, engine vibrations can cause wire harnesses to rub against the chassis, wearing down insulation and causing a short circuit to the ground. 2. Moisture or Corrosion in Connectors
