Accessing the security access code within module 09 – Central Electrics, using VCDS (Vag-Com Diagnostic System), is a common need for various adaptations and coding changes in Volkswagen vehicles. This article explores the process of locating this information and understanding its relevance.
Decoding the VCDS Scan for Security Access
Often, users need to access specific control modules to enable features or modify settings. A frequent scenario involves enabling the automatic window closing feature activated by the rain sensor. This requires access to module 09 – Central Electrics, which often necessitates a security access code.
One common issue arises when attempting to code the rain-closing window feature. Vehicles equipped with a Rain/Light Sensor (RLS) might not require a security code, while those with a Rain/Light/Humidity Front Sensor (RLFS) often do. This discrepancy suggests the security access requirement is linked to the specific sensor type in the vehicle.
The provided VCDS scan reveals crucial information about the vehicle and its modules:
- Address 09: Cent. Elect. (J519) – This line identifies the Central Electrics module, the target for our security access code.
- Part No SW: 5K0 937 086 Q and HW: 5K0 937 086 Q – These numbers indicate the software and hardware versions of the module. This information is critical when searching for coding procedures or troubleshooting issues.
- Component: BCM PQ35 M 122 0173 – This specifies the module as a Body Control Module (BCM) with a specific part number and version.
- Coding: 26000A3AD02F00C440080080040089EC0374000872A08120E4C400000040 – This long string represents the current coding of the module. Modifications to this coding string often require the security access code.
- Subsystem 1 – Part No: 1K0 955 559 AH Component: RLS 180314 05 54 0403 Coding: 07300A – This section confirms the presence of an RLS module in the vehicle.
Crucially, this scan does not explicitly provide the security access code. This code is usually not displayed directly in a standard scan.
Finding the VCDS 09 Security Access Code
So, how do you find the required code? Here are some common approaches:
- Official Channels: Consulting official factory repair manuals or contacting a dealership’s service department is the most reliable way to obtain the security access code. This information is often proprietary and requires authentication.
- Online Resources: Online forums dedicated to VCDS and Volkswagen vehicles often contain information shared by users who have successfully retrieved these codes. Websites specializing in VAG vehicle coding may also offer code retrieval services or databases. However, exercise caution with information from unofficial sources. Verify its accuracy before implementing any changes.
- Specialized Tools: Some advanced diagnostic tools might offer functionalities for retrieving security access codes.
Importance of Caution
Modifying vehicle settings using VCDS can have unintended consequences if not performed correctly. Incorrect coding can lead to malfunctions, error codes, or even damage to vehicle systems. Always research thoroughly, back up existing coding before making changes, and proceed with caution. When in doubt, consult a qualified professional.
Conclusion
While the VCDS scan provides valuable insights into the vehicle’s modules, including the Central Electrics module (09), it doesn’t directly reveal the security access code. Obtaining this code requires accessing official resources, utilizing specialized tools, or carefully researching reputable online communities. Remember, exercising caution and prioritizing accurate information is paramount when modifying vehicle coding. Improper coding can result in detrimental effects on vehicle functionality.
