Original wording in English

Actions: Perform a check for the internal defect failure description or DTC B2232-00 Fault momentarily not present: If (fault frequency counter <= 3) then clear the fault code memory, do NOT exchange the ECU, retest. If frequency counter > 3 then check whether there are sources of potential EMI close to the installed position of the ECU that do not comply with the standard vehicle configuration. Test not OK: Eliminate the source of EMI, Test OK: Inspect the ECU for any damages like water intrusion/corrosion damage inside the ECU from water? Test not OK: Rectify the damage to the ECU, clear the fault code memory, no parts exchange, Test OK: Is there a repeat of the anomaly for the same fault manifestation (with any ECU exchange)? If No: Clear the fault code memory, in-depth fault search in the environment of the ECU + in-depth questions to the customer about the situations when the fault occurred? *ECU-exchange only when an external failure cause can be ruled out.* If Yes: Replace the ECU. If (fault momentarily present) or (repeated repair with the same fault) Program the ECU with the most recent SW, repeat the check for the fault.

Repeated filings are grouped only when make, bulletin number, publication date and complete summary agree. Original record numbers are retained. Older publications remain available, and an explicit later version is shown when established. Pre-1994 vehicle associations are separated from default results; an unspecified year does not mean all model years apply.
