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 09-14-24 No.6 Security Access Procedure.)
