Adding Auxiliary Accelerator Pedal Below is a suggestion for adding an auxiliary accelerator pedal, based on the Mack LR dual steering solution. The pedal is wired in parallel using a multi-pin selector switch. If the signal is not switched between the two accelerator pedals, a fault code may be generated due to high current at the throttle pedal signal input line (VECU B-8). Note: See data link system before using such a device. Note: An identical pedal is needed for the auxiliary sensor accelerator pedal because it requires an IVS signal. A substitute type pedal may cause a fault code and is not recommended.
