TROUBLE CODE 16 4.20
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.
DIAGNOSTICS
Diagnostic Notes
The reference numbers below correlate with the circled num-
bers on the Code 16 flow charts.
1. The ECM is monitoring voltage at ECM connector [10]
(black) Terminal 1. Connect BREAKOUT BOX (Part No.
HD-42682) to ECM. See
4.6 BREAKOUT BOX .
2. This checks for voltage drops in the ECM power circuit. If
a significant voltage drop is not present, condition may
be caused by excessive starter current draw.
