Skim On-Board Diagnostic

The SKIM has been programmed to transmit and monitor many different coded messages as welll as PCM Bus messages. This monitoring is called "On-Board Diagnosis".

Certain criteria must be met for a diagnostic trouble code to be entered into the DKIM memory. The criteria may be a range of Input voltage, PCI Bus message, or coded messages to the SKIM. If all of the criteria for monitoring a circuit or function are met and a fault is sensed, a diagnostic trouble code will be stored in the SKIM memory.
