The defect only involves electrical connection modules manufactured by Connectral manufactured from week 95/16 to week 96/21. This directive requires the function checking of essential electrical circuits to detect defective electrical connection modules.","sortOrder":0}],"analysis":{"flash_summary_failed":{"failed":true,"reason":"Unauthenticated.
