1. A diagnostic system comprising:
- N dedicated diagnostic modules that each correspond with a respective one of a plurality of control systems and that each generate status signals indicating results of respective diagnostic tests, where N is an integer value; and
a diagnostic error time monitor that determines a first accumulated error time value corresponding to time between error events for each of said plurality of control systems based on said status signals and that selectively reports a fault to a respective one of said N dedicated diagnostic modules based on said first accumulated error time value.

Abstract
A diagnostic system includes N dedicated diagnostic modules that each correspond with a respective one of multiple control systems. The N dedicated diagnostic modules each generate status signals indicating results of respective diagnostic tests. A diagnostic error time monitor determines an accumulated error time value between error events for each of the control systems based on the status signals. The diagnostic error time monitor selectively reports a fault to a respective one of the N dedicated diagnostic modules based on the accumulated error time value.

13. A diagnostic method comprising:
-
generating status signals that indicate results of diagnostic tests that each correspond with a respective one of N dedicated diagnostic modules and a respective one of a plurality of control systems; transmitting said status signals to a diagnostic error time monitor; determining a first accumulated error time value corresponding to time between error events for each of said plurality of control systems based on said status signals; and selectively reporting a fault to a respective one of said N dedicated diagnostic modules based on said first accumulated error time value, where N is an integer value. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
