DTC P0381 GLOW INDICATOR LAMP - CIRCUIT MALFUNCTION
GENERAL DESCRIPTION
E7427052
Heating combustion chamber, glow plug increases fuel ignitibility and makes fuel in the foggy state easily when engine
is cold. Thus, glow plug makes engine starting easily and decreases exhaust gas produced just after turning engine on
when engine is cold.ECM controls operation and operating duration of glow plug relay which supplies power to glow plug
with ECTS signal, battery voltage and IG KEY ON signal.Through glow lamp in cluster, ECM let drivers know if glow plug
is ON.
DTC DESCRIPTION
E44CC376
P0381 is set when 1)excessive voltage is detected or 2)no current is detected like open or short to ground in glow lamp
control circuit for more than 1 sec. at glow lamp ON condition. This code is due to open in glow lamp control circuit or
internal open in filament of glow lamp component.
