A method for monitoring an engine starting system includes detecting a first engine crank command, monitoring engine speed states, and collecting the engine speed states in a first buffer disposed in a first controller. A second engine crank command is determined based upon monitored electric power states from a battery. The electric power states from the battery are collected in a second buffer disposed in a second controller. The engine speed states collected in the first buffer are synchronized with the electric power states from the battery collected in the second buffer based upon the first engine crank command and the second engine crank command. A starter resistance is determined based upon the electric power states from the battery. A telematics device communicates the starter resistance and the monitored engine speed states synchronized with the monitored electric power states to a remote system.
