WIRING: Emergency Reverse Check
An optional wire connected directly to the emergency reverse (belly button)
switch provides for broken wire detection
when that option is enabled at the
factory.
The emergency reverse check output wire provides a dc bias to the
emergency reverse circuit to check for continuity. If there is no continuity in
the circuit, the controller shuts down and a fault code is indicated.
This feature must be enabled at Curtis. If the option is selected and the
check wire is not connected, the vehicle will not operate. If the option is not
selected and the check wire is connected, no harm will occur—but continuity
will not be checked.
The emergency reverse check output wire is connected to Pin 10, as shown
by the dashed lines in the two basic wiring diagrams (Figures 3 and 4).
Alternatively, a 9.1 k
Ω
resistor can be wired directly across the emer-
gency reverse switch to provide the dc bias, as shown by the dashed line in
Figure 11.
