CLUTCH SWITCH

This input indicates that the clutch is released and is used for suspending Cruise Control and Auto
Resume. When the clutch is released, the input is at battery ground. Cruise Control is suspended
if the clutch is pressed once if Auto Resume is enabled. If the clutch is released within three
seconds, Cruise Control is automatically resumed.
The digital input logic for the Clutch Switch disables Cruise Control in the unlikely event of a
broken clutch switch wire.
If the transmission type is set to a two pedal system, the engine will know that there is no clutch
on the vehicle and will ignore the clutch switch input.
The Clutch Switch is a normally closed switch. It is customer selectable and is normally disabled.

Installation

The Clutch Switch is wired to the CPC on pin 4/8. Alternatively the Clutch switch may be
multiplexed on J1939. Refer to section 4.2, "Switch Inputs Received Over J1939 Data Link"
for additional information.

Programming Requirements and Flexibility

The options for this digital input are listed in Table 4-5.
