INSPECTION PROCEDURE
HINT:
Read freeze frame data usingthe hand−held tester.Freeze frame data records the engine conditions when
a malfunction is detected. When troubleshooting, freeze frame data can help determine if the vehicle was
running or stopped, if the engine was warmed up or not, if the air−fuel ratio was lean or rich, and other data
from the time the malfunction occurred.
1CHECK OPERATION OF SPEEDOMETER
(a) Drive the vehicle and check if the operation of the speedometer in the combination meter is normal.
HINT:
The vehicle speed sensor is operating normally if the speedometer display is normal.
NG CHECK SPEEDOMETER CIRCUIT (INCLUDE

DTC P0380 GLOW PLUG/HEATER CIRCUIT ”A”
CIRCUIT DESCRIPTION
The glow plug is mounted inside the engine combustion chamber. To ensure the efficient engine starting with
a cold engine, the ECM calculates a time interval of the current needs to flow through the glow plug depend-
ing on the starting engine coolant temperature when the ignition switch is turned to ON. The ECM then turns
on the glow plug relay and permits the current to flow through the glow plug based on the ECM’s calculated
time. The glow plug is then heated and enhances fuel combustion with a cold engine.
This DTC will be set if there is open in glow plug itself or its circuit.
HINT:
After the engine is started, the ECM performs an ”after−glow” for a certain period of time. In proportion to
the actual engine coolant temperature, the time period varies. The after−grow reduces diesel engine knock-
ing, white smoke and engine noises with a cold engine.

HINT:
S After completing repairs, confirm that P0380 is not present again.
S Read freeze frame data using the hand −held tester. Freeze frame data records the engine conditions
when a malfunction is detected. When troubleshooting, freeze frame data can help determine if the
vehicle was running or stopped, if the engine was warmed up or not, if the air −fuel ratio was lean or
rich, and other data from the time the malfunction occurred.
1 CHECK OTHER DTC OUTPUT(IN ADDITION TO DTC P0380)
(a) Connect the hand −held tester to the DLC3.
(b) Turn the ignition switch to ON and turn the hand −held tester ON.
(c) Select the item ”DIAGNOSIS / OBD/MOBD / DTC INFO / CURRENT CODES”.
(d) Read DTCs.

3 INSPECT FUSE(GLOW FUSE)
(a) Remove the GLOW fuse from the R/B No. 3.
(b) Check for continuity in the GLOW fuse.
Standard: Continuity
(c) Reinstall the GLOW fuse.
NG CHECK FOR SHORT IN ALL HARNESS AND

NOTICE:
SExercise extreme care not to damage the glow plug
pipes. Damaging them could cause an open circuit, or
shorten the life of the glow plugs.
SKeep the glow plug free of oil and fuel while cleaning.
SWipe any oil off the terminal and Bakelite washer with
a clean−dry cloth during inspection.
