SKREEM On-Board Diagnostics

SKREEM ON-BOARD DIAGNOSTICS
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.
