2008 Crown Victoria/Grand Marquis Workshop Manual SECTION 501-14: Handles, Locks, Latches and Entry Systems DIAGNOSIS AND TESTING Locks, Latches and Entry Systems Page 1 of 29 2008 Crown Victoria/Grand Marquis Workshop Manual Procedure revision date: 05/14/2009 Printable View (548 KB) Special Tool(s) 73III Automotive Meter 105-R0057 or equivalent Vehicle Communication Module (VCM) and Integrated Diagnostic System (IDS) software with appropriate hardware, or equivalent scan tool Flex Probe Kit 105-R025C or equivalent Material Item Multi-Purpose Grease XG-4 and/or XL-5, or equivalents Penetrating and Lock Lubricant (US); Penetrating Fluid (Canada) XL-1 (US); CXC-51-A (Canada) Specification ESB-M1C93-B — Principles Of Operation NOTICE: Do not use a key, pencil or any other hard object to press the keyless entry keypad buttons. These objects may damage the keypad buttons. NOTE: Upon installation of a new driver door module (DDM), the module must be reconfigured. Refer to Section 418-01. NOTE: Upon installation of a new DDM, the remote keyless entry (RKE) transmitters must be reprogrammed. Refer to Remote Keyless Entry (RKE) Transmitter Programming in this section. The DDM receives inputs from the digital transmission range (TR) sensor, the ignition switch, the brake switch, the door lock control switches, the lighting control module (LCM), the keyless entry keypad and the RKE transmitter. The DDM outputs consists of the keyless entry keypad illumination, the door lock actuators, the luggage compartment lid release solenoid, and the LCM. For DDM removal and installation information, refer to Section 419-10. Power Locks The power lock/unlock feature requests all of the vehicle doors to lock or unlock upon a request from the door lock control switch, the keyless entry keypad, or the RKE transmitter. Power locking and unlocking functions independently of the key position, the vehicle speed, or the transmission position. The LCM and the DDM activate internal relays to supply the correct power and grounds for the door lock actuators. Autolock The autolock feature locks all the doors when all the doors are closed, the key is in the ON position, the vehicle is shifted into any forward gear, and then the vehicle speed exceeds 5 km/h (3 mph). This feature relocks the doors (if any doors were open) after all the doors are closed and the vehicle speed has gone below and then exceeds 5 km/h (3 mph). Door ajar switches are wired directly to the DDM. The autolock feature can be enabled/disabled through module configuration. The autolock feature also uses inputs from the key position, the TR sensor, and the vehicle speed through the standard corporate protocol (SCP) network. Auto-Unlock The DDM energizes the unlock relay based on input from the door ajar switches and the vehicle speed signal. The DDM unlocks the doors when the following conditions are met:    The vehicle speed has exceeded 5 km/h (3 mph) then dropped to 0 km/h (0 mph) (vehicle stopped). The key is turned to the OFF or ACCY position. The LH front door is opened within 10 minutes of the key being turned to the OFF or ACCY position. The auto-unlock feature is cancelled if the doors are locked with the door lock control switch or the RKE transmitter within the 10 minute active window. After the 10-minute active window expires the auto-unlock feature does not unlock the doors if the driver door is opened. Smart Unlock With the key in any ignition position, and either the driver or passenger door open, the doors cannot be locked using the power door lock switches. The vehicle may still be locked with the key in the ignition, if one of the following actions is carried out:     Pressing the manual lock button on the door. Operating the RKE transmitter (if equipped). Operating the keyless entry keypad (if equipped). Operating the driver door with a key. Remote Keyless Entry (RKE) Transmitter http://www.fordtechservice.dealerconnection.com/pubs/content/~WS8A/~MUS~LEN/19/S... 9/18/2011 2008 Crown Victoria/Grand Marquis Workshop Manual Page 2 of 29 The RKE transmitter can be programmed using a scan tool or by using the ignition lock cylinder method. The RKE transmitter operates only if the vehicle is in PARK (P) or NEUTRAL (N). The RKE transmitter initiates the following electronic system functions:        Unlocks the driver door Unlocks all doors Locks all doors Arms/disarms the perimeter alarm or inhibits the alarm for the luggage compartment Activates/deactivates the panic alarm Commands the interior lamps on (when unlocking) and off (when locking) Sounds the horn once when LOCK is pressed twice within 3 seconds and the doors are closed The RKE transmitter has a normal operating range of 10 m (33 ft). Remote Keyless Entry (RKE) Transmitter Lock/Unlock Control — Unlock The RKE transmitter feature provides lock/unlock functions independently of key position, vehicle speed, or transmission position. The RKE transmitter feature provides a 2-step process for unlocking the doors. Upon receipt of the first request for unlocking the doors, the remote control feature requests the driver door module (DDM) to unlock the driver door only. If another unlock request is received within 3 seconds of the first, the RKE transmitter feature requests that all doors be unlocked. Remote Keyless Entry (RKE) Transmitter Lock/Unlock Control — Lock The RKE transmitter feature requests that all the doors be locked when the LOCK button is pressed on the RKE transmitter. On any press of the LOCK button with all doors closed, the RKE feature requests 1 flash of the parking lamps. If any door is ajar, no flash occurs, indicating the DDM locked all the doors but 1 or more doors are ajar. When the last door is closed, the vehicle provides 1 flash of the parking lamps. If 2 presses of the LOCK button are received within 3 seconds, the horn chirps once, and the parking lamps flash to indicate that all the doors are closed and locked. If any door is ajar when the second lock request is received within 3 seconds of the first, the RKE transmitter feature requests the horn chirp twice without flashing the parking lamps to indicate it locked all the doors but 1 or more doors are ajar. When the key is in the ON or START position, no parking lamp flashes or horn chirp confirmations occur. There are no parking lamp confirmations on police interceptor vehicles. Panic Alarm The panic alarm feature provides audible and visual alarms which are evident from the exterior of the vehicle. The panic alarm feature requests that the parking lamps flash and the horn sounds until deactivation. The flashing of the outputs occurs simultaneously. The panic alarm is activated by pressing the PANIC button on an RKE transmitter when the key is in the OFF position, or the key is out of the ignition lock cylinder. At all other times this feature is disabled. The panic alarm is deactivated by a second press of the RKE transmitter PANIC button, when the key is switched out of the OFF position, or when a period of 2 minutes and 45 seconds elapses since the initial activation. Keyless Entry Keypad The keyless entry keypad, located on the driver door, provides a method for the customer to access the vehicle or luggage compartment without a key or RKE transmitter. The keyless entry keypad feature:         locks all doors. unlocks only the driver door. unlocks all doors. programs/erases the customer key code. enables/disables autolocking and auto-unlocking. does not lock the doors if the driver door is open. arms/disarms the perimeter alarm. releases the luggage compartment lid latch by entering the keypad code plus 5/6 button. The keyless entry keypad feature operates independently of key position status, vehicle speed, or transmission position. When a keyless entry keypad button is pressed, the keypad buttons illuminate to provide better visibility. If LOCK ALL DOORS is entered or 5 seconds have elapsed since the last button press, the illumination is turned off. Each vehicle equipped with a keyless entry keypad is programmed with a 5-digit entry code. This code is provided to the customer through a wallet card. In addition, this code is available through a scan tool. When entering codes, each digit must be entered within 5 seconds of the previous button press. Anti-Scan Feature To provide added security, the keyless entry keypad is disabled for 1 minute after 35 button presses without a valid entry code being entered. The keyless entry keypad flashes during this 1-minute mode with all functionality disabled except for 7/8 and 9/0 still being allowed to lock the vehicle. Anti-Scan is turned off after 1 minute of keypad inactivity. Unlocking the Doors with the Keyless Entry Keypad To unlock the driver door, enter either the factory set code or the personal code (each digit must be pressed within 5 seconds of the prior digit). The interior lamps will illuminate. To unlock all doors, enter either the factory set code or the personal code (driver door unlocks) and press the 3/4 control within 5 seconds. Locking the Doors with the Keyless Entry Keypad It is not necessary to enter the factory set or personal code prior to locking all doors. To lock all doors, press the 7/8 and 9/0 controls at the same time.
