Results of self-testing of portions of an automotive vehicle's electronic instrument cluster are displayed on the cluster's speedometer and tachometer. A fault in a particular portion is indicated by operating the pointers of both meters in unison by repetitive sweeping from zero to a particular location corresponding to the particular portion containing the fault. Detection of no faults is indicated by sweeping both pointers in unison from zero to maximum and back. A person can judge the movements of the meters by observing whether the pointers sweep smoothly in unison or in an erratic manner.
