USER MANUAL
FCA WL/WS PASE System MY2021 Model:WXRFHM1
Model: WXRFHM1
The WXRFHM1 (Radio Frequency Hub Module) is an electronic body controller that
provides Passive and Active entry and start to the vehicle. The module
communicates with the other vehicle electronic devices via CAN FD. The
communication of the RFHM module and the KeyFOB is done via LF antenna coils
mounted inside and outside the vehicle (If equipped). The device is available
in the 433.92 MHz internal antennae (92 mm) and 433.92 MHz external antenna
(Fakra Connector) version.
The RFHUB system is a Passive Start and Entry (PASE) system that provides
enhanced customer convenience and security via a customer carried, passively
or actively enabled FOBIK communicating with the vehicle control module RFHUB.
A valid KeyFOB allows access to the vehicle’s passenger compartment, access to
the trunk, and use of the vehicle’s ignition controls.
The RFHUB System includes an RFHUB Module, an Ignition Module (KIN) containing
the Base station and Transponder coil, and a KeyFOB.
Use of the ignition controls is provided through a Keyless Ignition Node
module (KIN) located in the vehicle.
The LF antenna coils are driven by an LF Driver. The antenna components form a
series resonance circuit with a low Q factor. The purpose of the antenna is to
generate magnetic fields which are high enough to transmit data to the KeyFOB
and accurate enough for location recognition of the KeyFOB (outside/inside the
vehicle). The KeyFOB receives and processes this transmitted data. The KeyFOB
then sends its ID confirmation and data to the RFHM module via a 433.92MHz RF
signal. The RFHM also receives RKE information from the KeyFOB for Keyless
Access to commands such as “Lock”, “Unlock” and “Remote Start” and receives
TPMS RF Telegrams from TPMS sensors embedded in the tires. The RFHM is
designed to withstand and operate properly at the environmental extremes
typically encountered in a vehicle’s passenger compartment.
The FCA RFHM WL requires 2 different connectors to interface with the user and
other modules

Regulatory information
– FCC/ISED Owner Manual statement of compliance
NOTE: If the device itself is smaller than 8 cm x 10 cm, the statements
of compliance may be included in the device or vehicle owner/operator manual.
However, if the device itself is larger than 8 cm x 10 cm, then it is required
to have at least the first paragraph below placed on the device label or
housing.
This device complies with Part 15 of the FCC Rules and with Industry Canada’s
license-exempt RSS.
Operation is subject to the following two conditions: (1) This device may not
cause harmful interference, and (2) This device must accept any interference
received, including interference that may cause undesired operation.
Note: Changes or modifications not expressly approved by the party
responsible for compliance could void the user’s authority to operate the
equipment.
This equipment has been tested and found to comply with the limits for a Class
B digital device, pursuant to part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications. However,
there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and
on, the user is encouraged to try to correct the interference by one or more
of the following measures:
—Reorient or relocate the receiving antenna.
—Increase the separation between the equipment and receiver.
—Connect the equipment into an outlet on a circuit different from that to
which the receiver is connected.
—Consult the dealer or an experienced radio/TV technician for help.
