An interlock module is used to manage the machine interlock system. The
interlock module is attached to the underside of the seat pan
The interlock module is a micro-controller that senses the condition of various
machine switches (inputs). Based on the state of the inputs, the module controls
the engine ignition system circuit (circuit ground).
The interlock module is a solid state device, and there is no method to test the
module directly. The control module may be damaged if an attempt is made to
test it with an electrical test device, such as a digital multimeter.
1. Park the machine on a level surface, engage the parking brake, and shut off
the engine.
2. Ensure that the wire harness ground connection at the engine blower housing
is secure and free of corrosion.
3. Disconnect the wire harness connector from the interlock module
Check the wire harness connector for corrosion and clean the connector
if necessary.
