Keyless Entry: Testing and Inspection

The SKREEM has been programmed to transmit and monitor many different coded messages as well as PCI Bus messages. This monitoring is called On Board Diagnosis.

Certain criteria must be met for a diagnostic trouble code to be entered into the SKREEM memory. The criteria may be a range of; Input voltage, PCI Bus message, or coded messages to the SKREEM. 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 SKREEM memory.
