What is Security Access for Programming Your Saab

Reprogramming electronic modules in a Saab 9-3 NG often requires 'security access' to establish communication with certain critical systems. This access is essential for operations such as adding keys or pairing a module (e.g., a new CIM). This article explains how to obtain this access using Tech2 and GlobalTIS software.

What is Security Access?

Security access on Tech2 is a unique digital key that unlocks programming functions on your Saab's electronic modules. This system is designed to protect the vehicle against unauthorized or malicious use of diagnostic tools.

Security access is specifically required for the following operations:

• Adding or replacing keys.

• Programming injectors.

• Initializing new electronic modules (BCM, UEC, etc.).

Required Hardware and Software

To obtain security access, the following are required:

• A Tech2 with a CANDi module for vehicle communication.

• A PCMCIA card compatible with Tech2, containing the appropriate Saab software (e.g., version 148).

• A computer compatible with GlobalTIS installed.

How to Obtain Security Access with Tech2 and GlobalTIS

For better understanding, a step-by-step explanation is provided, accompanied by an illustrative GIF at the end of the article.

Why is Security Access Required?

Security access is used to perform advanced reprogramming and diagnostic operations on your Saab.

Connections and Preparation

• Connect Tech2 to your Saab 9-3's OBD2 port using the CANDi module.

• Insert the PCMCIA card containing the Saab software into Tech2.

• Connect Tech2 to your computer using the RS232 cable.

• Power on Tech2 and ensure it starts correctly.

Methods for Obtaining Security Access

Manual Request via Tech2

Navigate the Tech2 menu to the 'Security Access Request' option, then connect to GlobalTIS on your PC to finalize the request.

Note: For Tech2 to communicate with the computer, it is necessary to return to the main menu.

Automatic Request During Programming

If an attempt is made to program a module requiring security access (e.g., a CIM or a key), Tech2 will automatically generate the request and prompt the user to validate it using GlobalTIS.

Validation with GlobalTIS

• Launch GlobalTIS on your computer.

• Select 'Security Access Transfer'.

• Verify and confirm the vehicle's VIN.

• Transfer the validation algorithms to Tech2 to unlock access.

Precautions and Advice

• Ensure your Tech2 is correctly configured and all components are properly connected (computer, Tech2, CANDi module, OBD2 adapter...).

• Ensure that the version of Saab software on the PCMCIA card is compatible with the vehicle and the GlobalTIS software used.

• If uncertain about a step, consult a qualified professional.
