Abstract

An automotive vehicle electrical system diagnostic apparatus includes first and second electrical connections configured to electrically couple to an electrical system of an automotive vehicle which includes a battery. Digital samples are obtained during operation of the vehicle which are related to the system. The digital samples are stored in memory.

Claims

1. An automotive vehicle electrical system diagnostic apparatus for diagnosing operation of an electrical system of the vehicle, comprising:

a first electrical terminal configured to electrically couple to the electrical system of the automotive vehicle configured to receive an electrical system signal;

at least one input channel configured to couple to the electrical system of the vehicle, and receive a first electrical signal;

digital sample circuitry coupled to the first electrical terminal and the at least one input channel configured to provide a plurality of digital samples during operation of the vehicle which are related to the electrical system signal; and

a memory configured to store the plurality of digital samples as a function of the first electrical signal.
