Diagnostic Trouble Code Memory

The EGS control unit can detect 22 different defect codes with a series of additional information. It has room for 5 defect locations and their additional information in its defect code memory.

• Defect Location:  Defect text from DIAGNOSTIC TROUBLE CODE DEFINITIONS  table of defect codes is supplemented by the corresponding pin numbers of the control unit.
• Type Of Defect:  Indicated here is whether the defect is a break, a short to voltage, a short to ground or a plausibility error.
• Defect Currently Set (Diagnosis Version 2):  The response of the control unit to this statement can be in the affirmative, negative or conditionally affirmative or conditionally negative. In the case of a restricted reply to the question as to whether the defect code is currently set, the additional information "statement not sure since test condition is not currently fulfilled" appears. This means that the control unit cannot currently check the indicated defect code since, for example, the component is not active. However, the defect code was set or not set the last time the test condition was fulfilled.
• Intermittent Defect (Diagnosis Version 2):  The reply to this statement is in the affirmative when the defect disappeared at least once and the reappeared. Intermittent defect codes additionally indicated how often the defect disappeared and reappeared.
