Passive Anti-Theft System (PATS) Parameter Reset

PASSIVE ANTI-THEFT SYSTEM (PATS) PARAMETER RESET

Special Tool(s)

Special Tool(s):

NOTE:
- When using the IDS, the instrument cluster and the PCM parameters are reset at the same time.
- Once security access has been granted, multiple security access commands should be executed (if necessary) prior to exiting the command menu. This avoids an additional security access procedure and the associated 10 minutes time delay.

1. 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. Anti-Theft Security Access
3. From the scan tool, select: Parameter Reset and press the tick mark.

4. NOTE:
- If the instrument cluster was replaced, follow Steps 4-9. If the instrument cluster and the PCM were replaced, follow Steps 4-9. If only the PCM was replaced, cycle the key off, then back on, to complete the procedure.
- If steps 4-9 are followed, 2 keys must be present.

From the scan tool, select: Ignition Key Code Erase and press the tick mark.

5. Turn the key to the OFF position and disconnect the scan tool.

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. Remove the key and cycle the second key to the ON position for a minimum of 6 seconds (if it is an IKT key).
8. Both keys will now start the vehicle and will also operate the RKE functions of the vehicle (if they are IKT keys).

9. NOTE: The RKE data transfer will take place between the key and the instrument cluster first. After both keys are programmed into the instrument cluster, the RKE data will transfer from the instrument cluster to the smart junction box (SJB). Until the final data transfer takes place into the SJB, the RKE functions will not operate.

If more keys are required to be programmed, refer to Key Programming Using Two Programmed Keys. Using Two Programmed Keys
