DESCRIPTION
Programming procedures for the center panel switch packs has changed. The modules will no longer be plug and play, you will need to program and
assign the source address to the module for it to function properly. Review the scenarios below to determine which path to follow.

If a vehicle is down and cannot be programmed, unplug the #1 switch pack for 30 seconds. Then plug it back in. This will force all switch
packs modules to perform a source address claim at thier current software level, and will restore functionality. Disconnecting the batteries
will also work to force the switch pack modules to perform a new source address claim.
Example of What Happens to Switch Pack Source Addresses

07/31/2020 - An issue has been discovered with the door pod software. Programming fuctionality has been removed from DLB. This iKNow
article will be updated when the programming is corrected and functionality is restored.

DIAGNOSTIC STEPS
Check the kernel version of the parts that are currently installed in the vehicle, and the kernel of the new part if you are replacing a switch pack.
Part 1 - Check existing switch pack software in vehicle

1. Open DLB and delete the VIN from the vehicle you are planning to connect to if present
Figure 1 - Delete VIN from DLB

To delete the VIN from DLB:
1. Right click on the VIN you wish to delete
2. Navigate down and select "Delete..." as sown in Figure 1
2. Select the communication device you are using
Figure 2 - Select Com Link

3. Use the "Get Data" function in DLB to ensure the module data you are seeing is accurate. The key must be ON.
Figure 3 - Get Module Data

4. Note which kernel is being displayed for the Six Position Switch-Packs
◦ 17 or lower
◦ 22
Part 2 - Check replacement part switch pack software that you will be installing in the vehicle (if applicable)

1. Unplug the #1 switch pack
2. Plug the replacement part into the truck harness
3. Leave the remaining switch packs unplugged
◦ There will only be the single replacement part plugged into the truck harness
4. Unplug the pigtail from the last switch pack, and plug the pigtail of the replacement part back into the truck harness (yellow and green wires).
5. Connect with DLB and get the module data and check the kernel displayed
◦ 17 or lower
◦ 22 or higher
Determine the Programming Path to Follow
Updating modules from 17 or lower (no parts
being replaced, or service part is also at 17 or
lower)

Replacing switch pack - Truck switch packs are
at 17 - Replacement part is at 22

Replacing switch pack - Truck switch packs are Replacing switch pack - Truck switch packs are
at 22 - Replacement part is at 17
at 22 - Replacement part is at 22

If you are adding a switch pack to a vehicle, you will fall under one of the paths listed above. Instead of replacing any parts, you will be
adding an additional switch pack.
Switch Packs and Source Addresses
as Displayed in DLB Center Panel Tab

REPAIR STEP(S)
Updating modules from 17 or lower (no parts being replaced, or service part is also at 17 or lower):
1. If a switch pack is being replaced, move the switches over to the new switch pack, and plug the switch pack into its proper location in the vehicle.
◦ All switch packs should now be functional, and all kernel versions should be 17 or lower.
2. Key ON.
3. Navigate to the tools menu and select "Switch Pack Programming" as shown in Figure 4 below.

The BCM may need to be updated before you can update the switch pack software. If a BCM update is required, DLB will detect this and prompt
you to exit switch pack programming and update the BCM first. You will need to return to switch pack programming once the BCM has been
updated. If a BCM update is not required, DLB will continue with switch pack programming.

4. To start the programming process, you are asked to unplug the #1 switch pack. This will force the switch packs to perform a source address
claim.
◦ This step is not required if the vehicle is equipped with only one switch pack.

6. Status bar indicating programming progress while the switch packs program. All switch packs will be programmed automatically. Each switch
pack will take approx. 5 1/2 minutes to complete.

8. Figure 9 below is a prompt to check operation of each switch pack. This will help ensure the switch packs were at the proper source address
before programming was performed
◦ Clicking Yes - Programming is now complete, no further action is required.
◦ Clicking No - You will be given a dialogue box to manually set the source addresses based on the module serial number.
