Porsche Cayenne 955 957 Comfort Control Module - Used Original Parts

Diagnosis and Common Symptoms

From the workshop floor, the Comfort Control Module (also known as the KESSY module) in the first-generation Cayenne is a frequent source of perplexing electrical issues. The primary cause of failure is almost always water ingress from clogged plenum or sunroof drains, leading to corrosion on the mainboard. Diagnosis with a capable scanner like PIWIS will often reveal fault codes such as 01330 - Central Control Module for Comfort System (J393): No Communication, or specific circuit faults for door locks and window regulators.

Common symptoms of a failing module include:

• Intermittent or complete failure of the central locking system via remote fob.
• Power windows and sunroof operating erratically or not at all.
• Interior lights remaining on or failing to activate when doors are opened.
• "Key Not Recognized" or "Immobilizer Active" messages on the dashboard.
• The alarm system may trigger randomly or fail to arm/disarm correctly.
