MyKey(TM) Restrictions on Vehicle Operation

Pinpoint Tests

Pinpoint Test T: Cannot Program The MyKey(TM) Feature

Normal Operation

When the MyKey(TM) is used to operate the vehicle, the feature restricts several of the vehicle functions in order to promote good driving practices for the MyKey(TM) driver. Chimes sound and the audio system mutes if the safety belt is unbuckled. If the vehicle is low on fuel, chimes sound. Specific driver assistant functions are not allowed to be turned off, if configured by the MyKey(TM) feature. The audio volume can be configured to a limited value. Vehicle speed can be limited and chimes can be configured to sound when specific speeds are attained. The control functions for the MyKey(TM) feature are contained in the Instrument Panel Cluster (IPC). The IPC initiates the key interrogation sequence of the MyKey(TM) when the key is turned to the ON or START position (if equipped with an Intelligent Access (IA) system, if the vehicle is started using the push button start). If a key is inserted into the ignition lock cylinder (if equipped with an IA system, if the vehicle is started using the push button start) and either a MyKey(TM) menu does not appear in the message center and/or the key cannot be programmed as a MyKey(TM) with restricted status, it may be due to one of the possible causes listed below.

NOTE: The remote start system may or may not be programmed to a MyKey(TM) restricted key status. If it is not programmed to a MyKey(TM) restricted key status, the IPC recognizes it as the last possible remaining admin key. If it is programmed to a MyKey(TM) restricted key status and the vehicle is remote started, the IPC displays the MyKey(TM) welcome message. In this case, the key that is inserted into the ignition lock cylinder (for IA vehicles, if an IA key is inside the vehicle) may be mistaken for a MyKey(TM). This can only occur if the remote start system is non-Ford approved. If it is Ford approved, the vehicle stalls as soon as a door is opened or the vehicle is shifted into gear, causing the driver to insert their key into the ignition lock cylinder and cycle it to the ON position (for IA vehicles, start the vehicle using the start/stop switch with a programmed IA key inside the vehicle).

This pinpoint test is intended to diagnose the following:

- Unlimited key mode is turned on (only applicable to Integrated Keyhead Transmitter (IKT) vehicles)
- Remote start system (if equipped) is programmed as a MyKey(TM) restricted key
- Only one admin key left
- MyKey(TM) restricted key is in the ignition lock cylinder (IKT vehicles)
- MyKey(TM) restricted key is in the backup transceiver slot (IA vehicles)
- IPC



PINPOINT TEST T: CANNOT PROGRAM THE MYKEY(TM) FEATURE

-------------------------------------------------
T1 CHECK THE UNLIMITED KEY MODE STATUS


NOTE: Make sure the vehicle is not remote started. If the vehicle is remote started, the remote start system may have been programmed as a MyKey(TM) and therefore the configure/disable function is inoperative. This should not occur if the vehicle is equipped with a Ford approved remote start system. If the remote start system type cannot be verified, it is safer to make sure the vehicle is not remote started.

NOTE: This step is only for vehicles equipped with IKT keys. For vehicles equipped with IA keys, proceed to Step T2.

- Ignition OFF.
- Connect the scan tool.
- Ignition ON.
- Enter the following diagnostic mode on the scan tool: IPC DataLogger.
- Review the IPC PID UNL_KEY_MODE.
- Does IPC PID UNL_KEY_MODE display "Disable"?

Yes
GO to T2.

No
DISABLE the unlimited key mode. REFER to Spare Key Programming - Unlimited Key Mode Unlimited Key Mode.

-------------------------------------------------
T2 DETERMINE THE STATUS OF THE KEY IN QUESTION


NOTE: If the vehicle is equipped with IKT keys, insert it into the ignition lock cylinder. If the vehicle is equipped with IA keys, make sure it is the only IA key inside the vehicle. It does not have to be in the backup transceiver slot.

- Ignition OFF.
- Ignition ON.
- Observe the message center.
- Does the message center display "MYKEY ACTIVE, DRIVE SAFELY"?

Yes
The MyKey(TM) restricted key is already programmed and is in the ignition lock cylinder (for IA vehicles, the key inside the vehicle is a MyKey(TM) restricted key).
REFER to MyKey(TM) Programming Mykey if it is desired to configure or disable the MyKey(TM) feature.

If the concern is that the MyKey(TM) restricted key cannot be configured or disabled, GO to Pinpoint Test U. Pinpoint Test U: Cannot Configure/Disable The MyKey(TM) Feature

No
The key in the ignition lock cylinder is an admin key (for IA vehicles, the key inside the vehicle is a MyKey(TM) restricted key). GO to T3.

-------------------------------------------------
T3 REVIEW THE MESSAGE CENTER INFORMATION TO DETERMINE THE NUMBER OF ADMIN KEYS


- Using the admin key in the ignition lock cylinder (for IA vehicles, make sure the admin key is the only key in the vehicle), press the SETUP button on the message center control buttons until SYSTEM CHECK is displayed.
- Press RESET to review the message center information to determine how many admin keys are programmed into the IPC.
- Does the IPC message center indicate there are 2 or more admin keys programmed into the IPC?

Yes
GO to T4.

No
There must always be at least one admin key. The IPC does not allow the last admin key to be programmed into a MyKey(TM) restricted key. The concern is product characteristic. RELEASE the vehicle to the customer and explain the vehicle operating characteristics.

-------------------------------------------------
T4 CHECK FOR CORRECT IPC OPERATION


- Disconnect the IPC connector.
- Check for:
- corrosion
- damaged pins
- pushed-out pins
- Connect the IPC connector and make sure it seats correctly.
- Operate the system and verify the concern is still present.
- Is the concern still present?

Yes
INSTALL a new IPC. REFER to Instrument Panel, Gauges and Warning Indicators. RESET the parameters in both the IPC and the PCM. If equipped with an IKT key, REFER to Passive Anti-Theft System (PATS) Parameter Reset - Integrated Keyhead Transmitter (IKT) With Integrated Keyhead Transmitter (IKT). If equipped with an IA key, REFER to Passive Anti-Theft System (PATS) Parameter Reset - Intelligent Access (IA) With Intelligent Access (IA). PROGRAM the Passive Anti-Theft System (PATS) keys into the new IPC. If equipped with an IKT key, REFER to Key Programming Using Diagnostic Equipment - Integrated Keyhead Transmitter (IKT) Integrated Keyhead Transmitter (IKT). If equipped with an IA key, REFER to Key Programming Using Diagnostic Equipment - Intelligent Access (IA) With Intelligent Access (IA). TEST the system for normal operation.

No
The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.
