Programming Security Code

Security code programming is the first procedure that is required to program a new Theft Deterrent Module. It is programmed with the scan tool. The code consists of a four alpha numeric character combination and can only be programmed once. Thereafter, it can be neither altered nor erased. For this reason, proceed with great care. However, the security code is always entered twice for a cross check. The scan tool then compares the entered codes and evaluates the results. If a mismatch occurs, the input of the security code must be repeated.

IMPORTANT: When entering the security code with the Tech 2, use the arrow keys only. If a mistake is made when entering the security code (more than two times), a security wait time is internally activated by the module. After the first and second time a waiting period of 10 seconds each occurs respectively. The third time a waiting period of 10 minutes occurs. The waiting time doubles consecutively after the third time. An attempt to enter the security code during the waiting period will fail. Once the waiting period counts down to zero, programming is possible. You can view the security wait time with the scan tool. Select SECURITY WAIT TIME in the data list.
