No.4 Changing the Method For Registering Additional Keys
No.4 Changing the Method for Registering Additional KeysNOTE:
- This procedure is for changing the enable/disable setting of the "No.1 Additional Key Registration Procedure (Using Two Valid Keys)".
- The default setting for new vehicles and new instrument cluster replacement is "Enabled".
- By disabling the "No.1 Additional Key Registration Procedure (Using Two Valid Keys)", only the M-MDS can be used to register additional keys, thereby preventing two valid keys from being used to create an unauthorized spare key. This function is for use by rental car or other companies with vehicle fleets.
Procedure
1. Using any key, turn the ignition switch to the ON position. (Either a valid or an unregistered key can be used.)
NOTE: When using an unregistered key, although the security light flashes and DTC 15 is displayed, this does not indicate an improper procedure. Continue to perform the procedure as indicated.
2. Connect the M-MDS to the DLC-2.
3. Select "Body/Security/PATS function" from the M-MDS screen menu.
4. Perform security access as indicated on the M-MDS screen. (See No.6 Security Access Procedure.) No.6 Security Access Procedure

6. After verifying that the PATS function menu is displayed again on the M-MDS screen, select "Exit" to complete the M-MDS function.
7. After Step 6, wait 10 s or more and then turn the ignition switch to the LOCK position.
