"Battery Monitor & Engine Control Voltage"

This parameter sets a voltage trip point. When the voltage falls below the trip point the Engine Control Module (ECM) will automatically elevate the engine speed to the rpm that is specified in the "Battery Monitor & Low Idle Engine Speed" parameter.

Note: If the "Transmission Style" parameter is programmed to "AT/MT/HT Option 3" or to "AA/MT/HT Option 4", a neutral switch must be installed at Input #12 (J1/P1:62) of the ECM. A J1939 broadcast message will also enable this feature.
