P1611

DTC P1611

CIRCUIT DESCRIPTION
The scan tool is used to program the powertrain interface module (PIM). Before any programming, a security code must be entered into the scan tool. The PIM will check if the code entered is correct before continuing. If the security code is incorrect, DTC P1611 sets.

After an incorrect security code is entered, the PIM prevents any further attempts to enter a code until a predetermined wait time elapses. There are 6 wait time stages, and for each stage, an incorrect security code may be entered three times before the lockout time is escalated to the next stage.

The lockout stages are as follows:
- Stage 1 wait time is 10 seconds.
- Stage 2 wait time is 10 seconds.
- Stage 3 wait time is 10 minutes.
- Stage 4 wait time is 20 minutes.
- Stage 5 wait time is 40 minutes.
- Stage 6 wait time is 60 minutes.
