Diagnostic Trouble Codes (DTCS)

A diagnostic trouble code (DTC) is stored if the accessory electronic module (AEM) detects a fault. This control module can store up to 6 diagnostic trouble codes (DTCs), the 3 first and the 3 latest.

Should a fault disappear for any reason after being permanently stored in the control module as a diagnostic trouble code (DTC), the information remains stored in the memory.
