DTC P0622 GENERATOR FIELD ºFº TERMINAL CIRCUIT
CIRCUIT DESCRIPTION
While the generator is generating the current, the duty signal is sent from terminal M of the generator to the
ECM terminal ALT. The duty signal is used for detecting the open malfunction of the generator circuit and
DTC P0380.
DTC No.DTC Detection ConditionTrouble Area

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

INSPECTION PROCEDURE
HINT:

If different DTCs related to different systems that have terminal E2 as the ground terminal are output
simultaneously, terminal E2 may be open.

Read freeze frame data using \b
 . Freeze frame data records the engine conditions
when a malfunction is detected. When troubleshooting, it is useful for d\
etermining whether the vehicle
was running or stopped, the engine was warmed up or not, etc. at the time o\
f the malfunction.
1CHECK IF CHARGE LAMP IS ILLUMINATED
HINT:
Run the engine at 2,000 rpm, and check if the charge lamp located in the\
combination meter is OFF.
YESGo to step 3
NO
2CHECK HARNESS AND CONNECTOR(GENERATOR ± ECM)
(a)Disconnect the E13 ECM connector.
(b)Disconnect the A11 generator connector.
(c)Check for continuity between the wire harness side con- nector.
Standard (Check for open):
