Inspection and Verification


WARNING: Servicing must be carried out by personnel familiar with both vehicle system and the charging and testing
equipment. All operations must be carried out in a well ventilated area away from open flame and heat sources.


CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not
guarantee confirmation of a fault, and may also cause additional faults in the vehicle being tested and/or the donor vehicle.


NOTE: Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.
1. Verify the customer concern

2. Visually inspect for obvious signs of damage and system integrity

Face Level Registers System Operation

Operation of the face level registers is controlled by the ATC module, using LIN bus messages to the integral stepper motors. The four registers operate together in both the opening and closing phases.

The face level registers can be selected to run in one of two modes; 'automatic' or 'always open'. The mode is selected on the
climate control screen of the TSD.
Refer to: Navigation System (415-01 Information and Entertainment System, Description and Operation).

In the automatic mode, operation of the face level registers is synchronized with the engine START/STOP button. When the
engine starts the ATC module opens the registers. When the engine stops, the ATC module closes the registers.
If a face level register is fouled, when it receives an open or close request, the register concerned makes a number of
attempts to reach the requested position. If the register still does not move, it is left in the fouled position. The remaining
registers will continue to open and close as normal.

The automatic mode is disabled when the climate control system is off. The ATC module closes the registers if they are open in the automatic mode and the climate control system is selected off.

Diagnostics

If a fault occurs with the face level registers, a DTC (diagnostic trouble code) is stored in the ATC module. The DTC can be read using the Jaguar approved diagnostic system. The Jaguar approved diagnostic system can also initiate a self test routine
to check the operation of the face level registers.
Refer to: Climate Control System (412-00 Climate Control System - General Information, Diagnosis and Testing).


Air Ducts Component Description

The air ducts distribute air from the heater assembly to the registers and vents in the instrument panel and the center floor
console. Air ducts also direct air from the heater assembly into the front and rear footwells.

Registers and Vents

The registers control the flow and direction of air from the air ducts. The instrument panel contains four face level registers;
one at each end and two mounted centrally. For the rear seat occupants, two registers are installed in the rear face of the
center floor console. All of the registers incorporate vertical and horizontal directional vane adjustment and full air flow
adjustment down to zero.

The four face level registers in the instrument panel each contain an integral stepper motor. The stepper motors enable the
registers to rotate between the open and closed positions. In the open position, the registers have normal appearance and
functionality. In the closed position, the registers present a smooth surface flush with the surrounding instrument panel.

The vents are fixed outlets. There are four vents in the upper surface of the instrument panel; one in each end to direct air
onto the side windows and two along the front edge to direct air onto the windshield.
