Code No. P0622: Alternator FR Terminal System
OPERATION
The energized state of the alternator field coil is
inputted from the alternator (terminal No. 4) to the
engine-ECU (terminal No. 41).
FUNCTION
A signal of the power supply duty ratio for the
alternator field coil is inputted to the engine-ECU.
In response to the signal, the engine-ECU
detects the alternator output current and controls
the idling speed according to the output current
(electric load).
TROUBLE JUDGMENT
Check Condition
Engine speed is 50 r/min or more.
Judgment Criterion
Input voltage from alternator FR terminal is the
system voltage or more for 20 seconds.
PROBABLE CAUSE
Alternator FR terminal circuit open circuited
Failed engine-ECU
