Description Of Status Identifier

Status identifier

There are different status identifiers that can be read out for each diagnostic trouble code (DTC). The control module tests each connection more or less continuously. By reading out the diagnostic trouble code (DTC) and the associated status identifier (which detects the malfunction and stores the DTC), information about the test is obtained. Not all status identifiers need to be implemented in one control module, this varies from system to system. All status identifiers are reset and start counting again each time the control module is powered up and when erasing diagnostic trouble codes (DTCs). The possible status identifiers are described below.

Status identifier	Explanation
SI#01	The malfunction is validated now. Shows if the control module detects the malfunction right now. It is only when the test is in progress that the control module can detect malfunction and generate diagnostic trouble code.
SI#02	The malfunction is validated in the current operating cycle. Shows if the control module has detected the malfunction any time during this operating cycle.
SI#03	Intermittent not yet confirmed diagnostic trouble code.
SI#04	Confirmed diagnostic trouble code.
SI#05	Test status in current and/or earlier operating cycle. Shows if control module has performed test for this diagnostic trouble code in current and/or earlier operating cycle.
SI#06	The malfunction is validated in an earlier operating cycle. Shows if the control module has detected the malfunction any time during an earlier operating cycle.
SI#07	Test status in current operating cycle. Shows if control module has performed test for this diagnostic trouble code in current operating cycle.
SI#08	Request activate warning light/text message. Information about the diagnostic trouble code activates a warning light or text message.
