6E-128 Engine Control System (4JH1)
DTC P0381 (Symptom Code 4) (Flash Code 67)
Circuit Description
The glow indicator lamp is located on the instrument
panel (IP) cluster. The glow control system is operated
when the engine coolant temperature is low, which
allows easier engine starting. If the ignition switch is
turned ON when the engine coolant temperature is low,
the engine control module (ECM) illuminates the glow
indicator lamp and turns ON the glow plugs. After a
fixed time passes, the ECM turns OFF the glow
indicator lamp and the glow plugs. The ECM monitors
the glow indicator lamp control circuit for conditions that
are incorrect for the commanded state of the glow
indicator lamp. If the ECM detects an open circuit or
short to ground on the glow indicator control circuit, this
DTC will set.
Condition for Running the DTC
•
The ignition switch is ON.
Condition for Setting the DTC
•
The ECM detects that the low voltage condition on
the glow indicator lamp control circuit for longer
than 3 seconds when the lamp is commanded
OFF.
Action Taken When the DTC Sets
•
The ECM illuminates the malfunction indicator
lamp (MIL) when the diagnostic runs and fails.
Condition for Clearing the MIL/DTC
•
The ECM turns OFF the MIL when the diagnostic
runs and does not fail.
•
A history DTC clears after 40 consecutive driving
cycles without a fault. Or clear with the scan tool.
Diagnostic Aids
•
If an intermittent condition is suspected, refer to
Intermittent Conditions in this section.
Notice:
•
The glow indicator lamp is commanded OFF with
the ignition ON and engine OFF when the engine
coolant temperature is reached at 30°C (86°F).

1. Install the scan tool.
2. Turn ON the ignition, with the engine OFF.
3. Perform the Glow Indicator test with the scan
tool.
4. Command the Glow Indicator ON with the scan
tool.
Does the glow indicator lamp turn ON when
commanded ON with the scan tool?
Go to Step 3
Go to Step 4
3
Command the Glow Indicator OFF with the scan
tool.
Does the glow indicator lamp OFF?
Go to Step 15
Go to Step 9

1. Turn OFF the ignition.
2. Inspect the Meter (10A) fuse (C-14) in the cabin
fuse block.
Is the Meter (10A) fuse (C-14) open?
Go to Step 5
Go to Step 6
5
Replace the Meter (10A) fuse (C-14). If the fuse
continues to open, repair the short to ground on one
of the circuits that fed by the Meter (10A) fuse (C-14)
or replace the shorted attached component fed by
the Meter (10A) fuse (C-14).
Did you complete the repair?
