Order of inspection
P0381 Glow Plug/Heater Indicator Circuit Low
The P0381 code means there is a fault in the circuit of the glow plug indicator light on the dash. The system may still work, but the driver cannot tell when the glow plugs have finished heating. It is a low severity code, though worn glow plugs behind it will cause hard cold starts and white smoke.
