Overview

The flashing LEDs are used to visually alert individuals to the vehicles presence. The number and placement of flashing LEDs varies based on the police package ordered.

System Operation

System Diagram

Flashing LEDs

The flashing LEDs are turned on and off by zones. There are 4 zones for the flashing LEDs:

• Front park/turn/warn LED assemblies
• Grille flashing LEDs (if equipped)
• Tail lamp and front corner flashing LEDs (if equipped)
• High mount and decklid flashing LEDs (if equipped)

LED Flash Patterns

The LED flash patterns are preset from the factory and can be changed in 2 groups. Refer to LED Flash Pattern Programming.

The 2 groups are:

• Front park/turn/warn, grille, front corner and tail lamp flashing LEDs
• High mount and decklid flashing LEDs

When a flashing LED is replaced, the flash pattern of the replacement LED may be different than the rest in the group. Refer to LED Flash Pattern Programming.

Flashing LEDs Synchronization

The flashing LEDs are synchronized in up to 4 groups:

• Front park/turn/warn LED assemblies
• Grille flashing LEDs (if equipped)
• Tail lamp and front corner flashing LEDs (if equipped)
• High mount and decklid flashing LEDs (if equipped)

The flashing LED assemblies contain a module that controls the flash pattern and synchronizes the flashing LED with the other flashing LEDs in the group.

Flashing LED Controls

The flashing LEDs are driven and controlled by the following:

• Lighting relay center or lighting and siren control module
  • Controls the grille, front corner, tail lamp, high mount and decklid flashing LEDs
• Warn module
  • Controls the front/park/turn/warn LED assemblies

Component Description

System Diagram

Network Message Chart

 IPC Network Input Messages

Steering Wheel Auxiliary Controls

The steering wheel auxiliary controls use 2 switches labeled AUX and 4 positions labeled 1, 2, 3 and 4. Each switch position controls an output of the GFM. Each output of the module is switched to ground when commanded on. When the switch is pressed to one of the positions, the IPC message center displays AUX1, AUX2, AUX3 or AUX4, depending on the position selected, the GFM output will turn on and the outputs remain in that state until the switch is pressed again, then the outputs turn off.

Component Description

Steering Wheel Auxiliary Switches

The steering wheel auxiliary switches are located in the RH lower switch pack of the steering wheel. Each of the 2 switches are a 2-way momentary contact switch.

Generic Function Module (GFM)

The GFM receives input from the SCCM when the steering wheel switches are activated. The GFM then provides a grounded output for any equipment connected to it.

Normal Operation and Fault Conditions

The front park/turn/warn, tail lamp and front corner flashing LEDs typically have 2 versions of each pattern. If the flashing LEDs are set to the same version of the pattern, they will flash on and off at exactly the same time. If the flashing LEDs are set to different versions of the same pattern, they will flash on and off at exactly opposite times. If the flashing LEDs are out of synchronization, the on and off flash of the flashing LEDs may overlap and not flash the same or opposite.

The grille, high mount and liftgate flashing LEDs typically have 4 versions of each pattern. These flashing LEDs are made up of 6 individual LEDs. The addition of two more version of patterns control each side (3 LEDs) of an individual flashing LED. This allows the synchronization of each side of a singe flashing LED as well as each side of the vehicle.

GENERAL PROCEDURES

LED Flash Pattern Programming 

Individual LED Flash Pattern Programming

NOTE: When cycling through flash patterns, most flash patterns include an off/on pattern followed by an inverse on/off pattern. Setting the LED on one side to the on/off and the other to off/on creates the alternating pattern effect which should not be confused with synchronization which applies to the pattern timing between LED groups. For proper synchronization, the correct flash patterns must be selected for the individual flashing LEDs. Refer to the Explorer, Taurus Police Interceptor Modifier Guide for specific flashing LED patterns.

1. Disconnect the flashing LED to be programmed.

2. Connect ground to pin 4, component side of the flashing LED.

3. NOTICE: This step will activate the individual flashing LED. The flashing LED must be active to change the flash pattern.

   Connect 12 volts to pin 1, component side of the flashing LED.

4. Change the flashing LED flash pattern:
   • To cycle forward to the next pattern, connect 12 volts to pin 2, component side of the flashing LED for less than 1 second.
   • To cycle back to the previous pattern, connect 12 volts to pin 2, component side of the flashing LED for greater than 1 second.

Group LED Flash Pattern Programming

NOTE: When cycling through flash patterns, most flash patterns include an off/on pattern followed by an inverse on/off pattern. Setting the LED on one side to the on/off and the other to off/on creates the alternating pattern effect which should not be confused with synchronization which applies to the pattern timing between LED groups. For proper synchronization, the correct flash patterns must be selected for the individual flashing LEDs. Refer to the Explorer, Taurus Police Interceptor Modifier Guide for specific flashing LED patterns.
