TROUBLE CODE 16 4.21
GENERAL
Battery Voltage
A Code 16 will set if the ECM sees battery positive voltage
less than 6 volts or greater than 18 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
4.7 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.
Scanalyzer Notes
The Scanalyzer icon appears at those points in the flow chart
where the Scanalyzer can be used.
