WIRING: Emergency Reverse Check
An optional wire connected directly to the emergency reverse (belly button)
switch provides for broken wire detection when that feature is enabled at the
factory. The emergency reverse check output wire periodically pulses the emer-
gency reverse circuit to check for continuity. If there is no continuity, the
controller limits the vehicle to 15% speed and a fault code is indicated.
If the option is selected and the check wire is not connected, the vehicle
speed is limited to 15%. 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 24, as shown
by the dotted line in the basic wiring diagram (Figure 3).
