When the Electronic Control Module (ECM) or Electronic Control Unit (ECU) detects that the current flowing through the proportional control solenoid circuit is abnormally low, it triggers this diagnostic trouble code (DTC). The "05" suffix specifically identifies a "current below normal" or "open circuit" condition.
The suffix specifically refers to "Current below normal" or an Open Circuit , meaning the control module (EPOS) is detecting a break in the electrical path to that component. Initial Assessment & Safety doosan fault code vpv001-05
: Inspect the electrical harness connecting to the P1 pump for loose connections, corrosion, or frayed wires. An open circuit or high resistance in the wiring often triggers this "below normal" current code. When the Electronic Control Module (ECM) or Electronic
