Generic Electronic Module (GEM)

The GEM module is located on the right hand side, below the instrument panel. The GEM module controls the wiper and security systems.

Voice Activated Control Module (VACM)

The VACM is located in the left hand side luggage compartment behind the trim panel. The VACM module controls and processes all the
voice commands given by the driver, then delivers this information to the audio unit, navigation system module, television module,
intergrated cellular phones and the climate control modules which then carry out these commands.

Microphone

The microphone is used for the cellular phone and to receive voice commands. The microphone supplies the information to the VACM which
processes the commands and supplies the necessary information to the correct modules.

Visual Feedback Message Center Display

This display keeps the driver informed of the function which is being selected or processed.

Audible Feedback (Speakers)

This audible tone informs the driver when the system is able to receive commands for processing.

The verbal feedback speakers are incorporated in the audio speakers. These speakers are utilized to confirm to the driver that there verbal
command has been accepted and is being proceeded.

Steering Wheel Controls VOICE/PHONE Button

This button is automatically configured by the audio unit depending on which systems are installed on the vehicle. For additional
information, refer to the Owner Guide.

3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next

step.

4. If the cause is not visually evident, verify the symptom and refer to the Jaguar Approved Diagnostic System.

DTC Index

Voice Activated Control Module

CAUTION: when probing connectors to take measurements in the course of pinpoint tests, use the adapter kit, part number

3548-1358-00

• NOTE: if the control module/component is suspect and the vehicle remains under manufacturer warranty, refer to the W arranty Policy and
Procedures manual (section B1.2), or determine if any prior approval program is in operation, prior to the installation of a new module or
component.

• NOTE: When performing voltage or resistance tests always use a digital multimeter (DMM) accurate to three decimal places and with a
current calibration certificate. When testing resistance, always take the resistance of the DMM leads into account.

• NOTE: Check and rectify basic faults first before beginning diagnostic routines that involve pinpoint tests.

• NOTE: Inspect connectors for signs of water ingress, and pins for damage and/or corrosion.

• NOTE: If DTCs are recorded and, after performing pinpoint tests, a fault is not present, an intermittent concern may be the cause. Always
check for loose connectors and corroded terminals.
