Passive Anti-Theft System (PATS) Parameter Reset - Integrated Keyhead Transmitter (IKT)

Passive Anti-Theft System (PATS) Parameter Reset - Integrated Keyhead Transmitter (IKT)





1. Insert a programmed Passive Anti-Theft System (PATS) key into the ignition lock cylinder and turn the key from the OFF position to the ON position.

2. From the scan tool, enter TOOLBOX. Select BODY-SECURITY-PATS Functions and follow the on-screen instructions to ENTER SECURITY ACCESS. For additional information, refer to Anti-Theft Security Access - Integrated Keyhead Transmitter (IKT) Integrated Keyhead Transmitter (IKT).

3. From the scan tool, select: Parameter Reset and follow the on-screen instructions.

4. NOTE: The following steps are only necessary when an Instrument Panel Cluster (IPC) (with or without a PCM replacement) has been replaced. The parameter reset in the IPC and PCM has been completed.

NOTE: 2 keys must be present.

From the scan tool, select: Ignition Key Code Erase and follow the on-screen instructions.

5. Turn the key to the OFF position and disconnect the scan tool (the key does not need to be removed at this time).

6. NOTE: Integrated Keyhead Transmitter (IKT) keys require a 6-second programming time frame for the Remote Keyless Entry (RKE) data transfer to take place, while standard PATS keys only require a minimum of 3 seconds.

Turn the key to the ON position for a minimum of 6 seconds (if it is an IKT key).

7. Turn the first PATS key to the OFF position and remove the key from the ignition lock cylinder.

8. Insert the second PATS key into the ignition lock cylinder and turn the key to the ON position for 6 seconds (if it is an IKT key).

9. Both keys start the vehicle and also operate the Remote Keyless Entry (RKE) functions of the vehicle (if they are IKT keys).

10. NOTE: The RKE data transfer takes place between the key and the IPC first. After both keys are programmed into the IPC, the RKE data transfers from the IPC to the Smart Junction Box (SJB). Until the final data transfer takes place into the SJB, the RKE functions do not operate.

If more keys are required to be programmed, refer to Key Programming Using Two Programmed Keys - Integrated Keyhead Transmitter (IKT) Integrated Keyhead Transmitter (IKT).
