Control System68Service Manual – CS7000Service ModeThe service mode makes electrical troubleshooting faster and easier. It allows you to use the machineinterface to “read” some controller inputs and to “directly” turn on many outputs in order to quicklydetermine whether the problem is on the “input side” or the “output side” Some outputs (like the scrubbrush motors) are only turned on when other conditions are met, such as when the machine is moving. Itcan be difficult to check for voltage to the scrub brush motors while the machine is moving. Also, if voltage isnot present, it leaves in question what other input conditions may not have been met yet. The service modesolves these problems for you by allowing you to request that the controller ignore all other conditions anddirectly turn on the scrub brush motors (or other output loads).Note: Beginning around August 2015, an updated main machine controller software ID 56111560expands the capability of service test mode by allowing you to monitor several new dataparameters including current sensor inputs.Enter the service mode through the “Configuration Menu”.1. While holding down both the left and right turn signal switches, turn the key switch on.2. Continue to hold the switches down until the “Configuration Menu” is displayed, then release theswitches.3. Press and release the scrub pressure decrease button several times to scroll down the menu list until thearrow cursor is aligned with the “15 Service Menu” selection.
