TROUBLE CODE 16

GENERAL

Battery Voltage

A Code 16 will set if the ECM detects battery positive voltage
less than 6 volts or greater than 20 volts.
A low voltage condition typically occurs during activation
of the starter or generally indicates loose wire connec-
tions.
A high voltage condition is usually caused by a faulty
voltage regulator.

a significant voltage drop is not present, condition may
be caused by excessive starter current draw.
