Transmission Low Flow Control
Input Configuration Hard wired Input
J1939 The ASC Enable (Cruise Control Active) “switch” is used as the entry into ASC operation. The ASC Enable / Disable signal can be communicated to the transmission over CAN using J1939 (PGN 65265, SPN 595) or via a hardwired single pole, double throw switch. The method of communicating this signal must be configured in Cat ET. The configuration in Cat ET applies to the ASC Enable/Disable and ASC Set/Hold Mode signals. Therefore, all messages must either be communicated over J1939, or by using hardwired switches.

Illustration 44 g06260592When communicating the DTOC Enable status using a single pole, double throw hard wired switch, refer to Illustration 44.ASC Set / Hold Mode (Cruise Control States) Switch
The ASC Set / Hold Mode (Cruise Control States) switch is used to select the ASC operating mode (Set or Hold). The description of the Set and Hold modes can be found in the"ASC"Set" / "Hold" Mode Function" section. The ASC Set / Hold signal can be communicated to the transmission over CAN using J1939 (PGN 65265, SPN 527) or via a hardwired single pole, double throw switch. The method of communicating this signal must be configured in Cat ET. The configuration in Cat ET applies to the ASC Enable/Disable and ASC Set/Hold Mode signals. Therefore, all messages must either be communicated over J1939, or by using hardwired switches.
