Abstract
Automotive vehicle test equipment includes a controller which controls power supplied to a test circuit. The controller monitors a sleep mode switch which determines whether the controller enters a sleep mode. In sleep mode, the controller disconnects the test circuit from a power source. The controller also monitors a telephone line. Upon detection of a ring signal on the telephone line, the controller connects the test circuit to the power supply.
