Land Rover Defender: Glass, Frames and Mechanisms - Description

DRIVER DOOR SWITCHPACK

NOTE: RHD is shown, LHD is similar.

The driver door switchpack is powered by the DDM. When the switches in the driver door switchpack are used, the switchpack translates the switch movement into a Local Interconnect Network (LIN) message. A LIN connects the driver door switchpack to the DDM. Each passenger window switch is hardwired to the related door module.

PASSENGER DOOR SWITCHPACK AND REAR DOOR SWITCHPACK

NOTES:

• Vehicle with 5 doors is shown, vehicle with 3 doors is similar.
• RHD is shown, LHD is similar.

1. Rear right door switchpack - Vehicle with 5 doors only
2. Rear left door switchpack - Vehicle with 5 doors only
3. Passenger door switchpack

Individual window switches are installed in each of the 3 doors. Window switches for all of the windows and a rear door window isolation switch are installed in the driver door switchpack.

All window switches are of the non-latching rocker type. The switches have 2 switching positions in each direction, inch up/down and one-shot up/down. Operating the switch to the second detent position activates the one-shot feature.

DOOR MODULES

NOTES:

• Vehicle with 5 doors is shown, vehicle with 3 doors is similar.
• RHD is shown, LHD is similar.

1. DDM
2. DRDM - Vehicle with 5 doors only
3. PRDM - Vehicle with 5 doors only
4. PDM

The door modules are installed in the door of their respective windows. Each door module controls the following door window operation features in the respective door:

• Door window open and close.
• One-shot open and close.
• Closing anti-trap protection.

In addition to controlling the window lift system, the front door modules also control:

• Door locking.
• Door mirror adjustment and heating (front doors only).
• Door mirror lamps (front doors only).
• Mirror proximity cameras (front doors only).

When the driver door switchpack is used, it outputs a request message to the DDM through the LIN. The message is for the passenger door window or rear door windows. The DDM relays the message to the relevant door module through the HS CAN body systems bus.
