SKREEM On-Board Diagnostics
WARNING: This page is about a different car, the 2006 Dodge Sprinter. However, it is still accessible from the selected car via links, so may be relevant.
The SKREEM has been programmed to transmit and monitor many different coded messages as well as CAN Bus messages. This monitoring is called On-Board Diagnostics. Certain criteria must be met for a DTC to be entered into SKREEM memory. The criteria may be a range of; input voltage, CAN Bus message or coded messages to the SKREEM. If all the criteria for monitoring a circuit or function are met and a fault is detected, a DTC will be stored in the SKREEM memory and the START ERROR indicator will be turned on in the instrument cluster.
