RM38N0EC _57 Power Source / Network _111789 M20C-FKS, M20D-FKS BATTERY / CHARGING _0506213 CHARGING SYSTEM C

M20C-FKS, M20D-FKS BATTERY / CHARGING  CHARGING SYSTEM  P062049  Generator Control Circuit Internal Electronic Failure  


DESCRIPTION

The alternator performs self-diagnosis of its internal circuits to detect malfunctions (open or short circuits).

The ECM receives the result via LIN communication and stores a DTC.

DTC No. Detection Item DTC Detection Condition Trouble Area Warning Indicate Note
P062049 Generator Control Circuit Internal Electronic Failure Open or short in EXC circuit, or abnormal waveform for PH circuit.
(1 trip detection logic) 		Generator assembly Charge warning is displayed SAE Code: P0620

HINT:

A charge warning is displayed only when the malfunction continues.
