Rear Drive Halfshafts Component Description

The solid-steel halfshafts are of unequal length, with each halfshaft comprising inner and outer CV (constant velocity) joints.
The CV joints are the 'ball and socket' type packed with grease and protected by gaiters.

The outer CV joint is an interference fit into the wheel hub and secured by a locking nut. The inner CV joint is a slide fit and is
retained in the differential with a spring clip.

is routed from the EVAP canister purge valve to the inlet of the intake manifold (naturally aspirated vehicles) or the supercharger (supercharged vehicles). The EVAP canister purge valve is controlled by the ECM and is operated when engine operating conditions are correct to allow purging of the EVAP canister. The EVAP canister purge valve is a solenoid operated valve which is closed when de-energized.

A vapor pipe, which runs parallel with the fuel delivery line under the LH side of the vehicle, connects the EVAP canister purge valve to the EVAP canister.
The EVAP canister purge valve is operated at 10 Hz by a PWM (pulse width modulation) signal from the ECM. At this high frequency, the pulses of fuel vapor flow into the intake manifold/supercharger in an almost continuous flow. The valve operates
between 7% and 100% duty or mark space ratio (percentage open time).

Atmospheric pressure is higher than the pressure at the inlet of the intake manifold/supercharger under all throttle settings
and engine running conditions. It is this pressure differential that causes air to flow through the EVAP system to the engine. EVAP CANISTER PURGE VALVE

Fluid level too high/low
Poor condition of fluid
Fluid leak
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 check for diagnostic trouble codes (DTCs) and refer to the DTC Index.

DTC Index


CAUTION: When probing connectors to take measurements in the course of the pinpoint tests, use the adaptor kit, part
number 3548-1358-00.
NOTES:


If the control module/transmission is suspect and the vehicle remains under manufacturer warranty, refer to the Warranty
Policy and Procedures manual (section B1.2), or determine if any prior approval programme is in operation, prior to the
installation of a new module/transmission.


Generic scan tools may not read the codes listed, or may read only five digit codes. Match the five digits from the scan
tool to the first five digits of the seven digit code listed to identify the fault (the last two digits give additional information
read by the manufacturer approved diagnostic system).


When performing electrical voltage or resistance tests, always use a digital multimeter (DMM) accurate to three decimal
places, and with an up-to-date calibration certificate. When testing resistance, always take the resistance of the DMM leads
into account.


Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.


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


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

inlet duct downstream of the blower, where any heat generated during operation is dissipated by the air flow.

Auxiliary Coolant Pump

On all vehicles except 3.0L, an auxiliary coolant pump is installed on the rear right side of the radiator housing, in the return
line from the heater core. The auxiliary coolant pump is an electric pump that boosts the flow of coolant through the heater
core.

Ventilation Outlets

The ventilation outlets allow the free flow of air through the passenger compartment. The outlets are installed in the LH and
RH rear quarter panels, below the rear lamps. Each ventilation outlet consists of a grille covered by a soft rubber flap, and is
effectively a non-return valve. The flaps open and close automatically depending on the pressure differential between the air
inside and outside the vehicle.

Climate Control - Control Components - Overview
Description and Operation

Overview Published: 11-May-2011

The climate control system is controlled by the ATC (automatic temperature control) module. It controls the heating and
ventilation system and the A/C (air conditioning) system to regulate the temperature, volume and distribution of air into the
passenger compartment. The system is a fully automatic dual zone system capable of maintaining individual temperature
levels selected for the LH (left-hand) and RH (right-hand) sides of the passenger compartment, up to a maximum differential
of approximately 3 ºC (5.4 ºF). Manual overrides for the system include inlet air source, blower speed and air distribution.
These selections can be made using either the soft switches on the home and climate control screens of the touch screen
display (TSD), or the switches on the integrated control panel.
The ATC module also controls: The rear window heater.
The windshield heater (where fitted).
The exterior mirror heaters.
The seat heaters (where fitted).
The steering wheel heater.

Amber warning triangle
illuminated in LCD accompanied with a single
chime The water in fuel sensor in the fuel filter
has detected water in the fuel system. Drain fuel filter to remove collected
water. Odometer Display

The odometer displays the total distance which the vehicle has traveled. This is calculated by the instrument cluster using
wheel speed signals from the ABS module.
The odometer can show 6 characters and distances up to 999,999 miles or kilometers. The total distance travelled is stored in a
EEPROM (electrically erasable programmable read only memory) and the RAM (random access memory). This ensures that the
total distance is not lost if the battery is disconnected.

The odometer value is passed to other vehicle system modules on the medium speed and high speed CAN bus. This is used to record the total vehicle mileage for diagnostic purposes and when storing DTC (diagnostic trouble code)'s.
