Switch Light Patterns
The green light on the push-button programming switch indicates the
system's mode by its different light sequences. It is important to know
what the various patterns mean in order to respond appropriately to
system prompts.
STEADY FLASH
The light will turn on and stay for at least (1) second.
BLINKING FLASH
When the lights on the programming switch are BLINKING (single
ash on and off), this indicates that the system is in READY mode.
READY mode lasts for only (3) seconds while it waits for the next
command before timing out and turning itself off.
FLICKER FLASH
When the lights on the programming switch are FLICKERING (ash-
ing rapidly), this indicates that the system is in LEARN mode.
DOUBLE FLASH
When the lights on the programming switch DOUBLE FLASH (ash twice and stop), this indicates
that the system has acknowledged the program function. It typically exits the LEARN mode after a
DOUBLE FLASH.
Programming and Erasing FOBs
This section describes the steps to add and delete FOBs.
NOTE: It is important to know what the various switch light patterns mean in order to
respond appropriately to what the system is prompting.
NOTE: Three pre-programed FOBs are assigned to each vehicle system from the factory
and nothing needs to be done upon arrival or installation.
Up to (31) FOBs can be programmed to operate a single vehicle. (Where multiple drivers could access
a single vehicle.) Also, a single FOB can be assigned to operate any number of vehicles. (A service
mechanic may program a "master" FOB to access multiple vehicles.) In each case, the depot managers
should review the needs and risks of multiple and cross-functional FOBs.

Adding a New FOB
NOTE: A valid FOB paired to the system has to be used to start the programming
sequence in order for the system to recognize the additional FOB.
NOTE: Each FOB has to be added individually.
1. Stop the vehicle and turn off the engine.
2. Using a FOB paired to the vehicle, press the button once to prompt the READY mode
(BLINKING ash) on the programming switch. READY mode will last for (3) seconds before
timing out.
3. Press and hold the programming switch for (5) seconds to enter the LEARN mode. The switch
will FLICKER ash to indicate that it is in LEARN mode.
4. Press and release the button on the unpaired FOB. The programming switch will STEADY ON
ash then DOUBLE ash to indicate the FOB is paired and immediately exit the LEARN mode.
5. Now the original FOB and the added FOB are programmed to the vehicle.
6. Test the new FOB to verify door operation.
7. Repeat the steps to add another FOB.
Erasing FOBs
Quick Erase
This section explains how to delete (deny access to) all FOBs that have been programed to a single
vehicle. If a FOB is lost or stolen, this process will disable its access.
NOTE: A valid FOB paired to the system has to be used to start the programming
sequence. The paired FOB used to start this sequence will be the only one programmed
to the vehicle when completed.
1. Stop the vehicle and turn off the engine.
2. Using a FOB paired to the vehicle, press and release the button once to prompt the READY
mode (BLINKING ash). It will stay in READY mode for only (3) seconds before timing out.
3. Press and hold the programming switch for (20) seconds to enter ERASE (BLINKING ash).
The programming switch will STEADY ash and FLICKER ash before exiting the ERASE
mode automatically. The vehicle will now only recognize the FOB used to enter the READY
mode and delete access to all other paired FOBs.
4. FOBs can now be paired to the system using the Adding a New FOB process.
NOTE: If the lost FOB was programmed to multiple vehicles, each vehicle will need be
reprogrammed separately.

Erase ALL
This section explains how to use delete (deny access to) all FOBs that have been programmed to a single
vehicle at the module. Use this process only if NO recognized FOBs are available to erase FOBs.
NOTE: A FOB is NOT required or used to start this process, but at least one FOB will
need to be assign to the vehicle.
1. Stop the vehicle and turn off the engine.
2. Remove overhead panel cover.
3. Remove the TACT switch plug.
4. Press and hold the TACT switch for (20) seconds. The LED light on the module will turn on and
continue BLINK ash.
5. After (20) seconds, the LED will glow solid to indicate ALL ERASE mode and all paired FOBs
have been erased. (Do NOT let go of the TACK switch.) Continue to hold the TACK switch for
approximately 1-1/2 minutes. The LED will FLICKER ash once it enters LEARN mode.
6. Release the TACT switch.
7. Press the button on the FOB to be added. The programming switch lights will DOUBLE ash to
indicate the acknowledged FOB and immediately exit the LEARN mode.
8. Test the FOB to verify that it has been paired correctly.
NOTE: Only one FOB can be programmed using the ERASE ALL process.
9. Reinstall the plug.
10. Additional FOBs can now be added using the Adding a New FOB process.

Troubleshooting
FOB Testing
NOTE: The module LED should ash in a heartbeat pattern during normal operation.
After (1) hour, the LED turns off and enter sleep mode.
1. Press and release FOB button to unlock passenger door. The module LED should FLICKER ash
every (1) second and will be brighter.
2. If the module LED FLICKER ashes (2) seconds, the FOB signal is received but the FOB is
NOT paired. See Adding a New FOB to pair a FOB to module.
3. If the LED FLICKER ashes (8) seconds or more, the FOB signal is received and FOB is paired.
4. If LED does NOT FLICKER ash (maintains heart beat pattern only), then no transmission is
being received (FOB or module malfunction).
5. Use a FOB paired to another vehicle to repeat steps 1-3. If module LED FLICKER ashes with
FOB pair to another vehicle, the original FOB is NOT transmitting.
6. Replace battery on FOB and repeat test. If no change in heartbeat LED after new battery, FOB is
malfunctioning.
Note: It is NOT necessary to pair a FOB after the battery is replaced. The pairing data
is stored in non-volatile memory on the FOB.
7. If the LED does not FLICKER ash with known good FOB, module is defective. See System
Testing 1.2 – 1.5.
