DTC P0622 GENERATOR FIELD ”F” TERMINAL CIRCUIT
CIRCUIT DESCRIPTION
While the generator (alternator) is generating current, a duty ratio is sent from terminal M of the generator
to the ECM terminal ALT. This duty ratio is used for detecting an open malfunction of the generator circuit
and DTC P0380.
HINT:
DTC P0380 is prepared for indicating an open or short malfunction in the glow plug circuit. If this DTC is de-
tected, inspect the glow plug circuit. (See page 05 −386)

HINT:
After confirming DTC P0622, check the internal fuel pressure of the common rail in the ”DIAGNOSIS / OBD/
MOBD / DATA LIST / ALL / GENERATOR” using the hand −held tester.
Result:

MONITOR DESCRIPTION
The ECM will detect a generator (alternator) failure or an open malfunction of the circuit, if the duty ratio is
not output from terminal M of the generator (alternator) despite running the engine.

WIRING DIAGRAM
Refer to DTC P0380 on page 05 −386.
INSPECTION PROCEDURE
HINT:
SIf different DTCs related to different systems that have terminal E2 as the ground terminal are output
simultaneously, terminal E2 may have an open circuit.
SRead 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 IF CHARGE LAMP IS ILLUMINATED
HINT:
Run the engine at 2,000 rpm, and check if the charge lamp located in the combination meter remains illumi-
nated.
YES Go to step 3
NO
2 CHECK HARNESS AND CONNECTOR(GENERATOR (ALTERNATOR) −ECM)
(a) Disconnect the E13 ECM connector.
(b) Disconnect the A11 generator (alternator) connector.
(c) Check the resistance between the wire harness side con-
nectors.

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.
