A system and method for tracked vehicle dynamometer testing. The dynamometer system may be configured as a treadmill electric chassis dynamometer having dual, parallel endless belts positioned as substantially flat surfaces with cleats, i.e., the tracks of a test vehicle and a dynamometer vehicle. The track assemblies of the test vehicle and the dynamometer vehicle are generally vertically, mechanically coupled in close contact with each other via a retention fixture. The testing may be conducted in a climatic chamber to simulate various environmental conditions.

A method of verifying the integrity of an arithmetic logic unit (ALU) of a control module includes inputting a first test value into one of a plurality of registers of the ALU and inputting a second test value into remaining registers of the plurality of registers. A first set of operations is performed between the one of the plurality of registers and each of the remaining registers to produce a first set of results. A fault is indicated when one of the first set of results varies from a first predetermined result.
