Description Important note on the circuit diagram The wiring in the vehicle is only depicted according to the standard circuit diagram. Use the vehicle-specific circuit diagram for the test. Setting parameters of the load transmitter CAN SAE 1939 / IES Explanation of the display: The following paragraph explains the terms used in the diagnosis function [E].
Type | Displays the load transmitter type specified in the data record. The control unit can, however, not recognize whether this type is really installed in the vehicle. In case of a fault, you should therefore first check whether the indicated type is really installed. This means that a different type was installed in this case as otherwise the vehicle would have been delivered with wrong periphery.
Function | Displays the status of the function, i.e. whether the load transmitter operates correctly within the specified thresholds. ATTENTION! - Load transmitter faults are only admitted to the fault memory during a shift operation; a fault occurring during startup of the load transmitter, while the vehicle is stationary, does not cause an entry in the fault memory.
Stage | The control unit divides the input signal range of all load transmitter types in 7 stages [0 - 6]. The calculated stage is displayed here. Stage 7 is set for kick-down signals. In the event of a fault, stage 7 is also assumed as safe condition.
Kickdown | Kick-down is a separate input signal. The display allows this input signal to be controlled. Stage 7 is assumed if the kick-down signal is activated.
Value | The physical value of the input signal is displayed as actual or standardized quantity - [ms], [V] or [%].
