General Information - Road/Roller Testing
Description and Operation Published: 11-May-2011

Road or roller testing may be carried out for various reasons and a procedure detailing pre-test checks, through engine starting
and stopping, pre-driving checks, on-test checks to final checks on completion of the test is given in this section.

Unless complete vehicle performance is being checked, the full road test procedure need not be carried out. Instead, those
items particularly relevant to the system/s being checked can be extracted.

Pre - Test Checks


WARNING: If the brake system hydraulic fluid level is low, pedal travel is excessive or a hydraulic leak is found, do not
attempt to road test the vehicle until the reason for the low fluid level, excessive pedal travel or hydraulic leak is found and
rectified.

It is suggested that pre-test checks, and functional tests of those systems/circuits which affect the safe and legal operations
of the vehicle, such as brakes, lights and steering, should always be carried out before the road or roller test.

Engine oil level
Engine coolant level
Tires, for correct pressure, compatible types and tread patterns, and wear within limits
There is sufficient fuel in the tank to complete the test
All around the engine, transmission and under the vehicle for oil, coolant, hydraulic and fuel leaks. Make a note of any
apparent leaks and wipe off the surrounding areas to make it easier to identify the extent of the leak on completion of
the test
Starting the Engine


CAUTION: On initial drive away from cold and within the first 1.5 km (1 mile), do not depress accelerator pedal beyond
half travel until the vehicle has attained a minimum speed of 25 km/h (15 miles/h). Never operate at high engine speed or
with the accelerator pedal at full travel whilst the engine is cold.
With the ignition switched off, check:
The parking brake is applied
The transmission selector lever is in Park
All instrument gauges (except fuel gauge) read zero

With the ignition switched on, check:

Ignition controlled warning lamps come on
Engine coolant temperature gauge registers a reading compatible with the engine coolant temperature
Fuel gauge registers a reading appropriate to the fuel level in the tank
The operation of the parking brake and brake fluid level warning lamps

On Road or Roller Test Check:


CAUTION: If road testing, check the brake operation while still travelling at low speed before continuing with the test. If
the brakes pull to one side, or appear to be otherwise faulty, do not continue with the road test until the fault has been found
and rectified.
Initial gear engagement is smooth
Parking brake control operates smoothly and the parking brake releases quickly and completely
Transmission takes up the drive smoothly, without judder
The engine power output is satisfactory, full power is achieved, acceleration is smooth and pedal operation not stiff or
heavy, and engine speed returns to idle correctly
There is no excessive or abnormally colored smoke from the engine under normal driving, heavy load or overrun
conditions
Steering operation, including power steering, is smooth, accurate, not excessively heavy or with excessive free play or
vibration. Does not pull to one side and self centres smoothly after cornering
Speedometer, oil pressure warning lamp, coolant temperature gauge and tachometer register the correct readings or
operate correctly
Switches and controls operate smoothly and positively, warning lamps operate correctly and the direction indicator
control self cancels when the steering is returned to the straight ahead position
Heating and ventilation systems work correctly and effectively
Brake operation and efficiency

Brake Testing


WARNING: When brake testing, avoid breathing the smoke or fumes from hot brakes, this may contain asbestos dust
which is hazardous to health, see Health and Safety Precautions.

General Information - Diagnostic Trouble Code (DTC) Index DTC: Headlamp
Control Module (HCM)
Description and Operation

Headlamp Leveling Control Module (HLCM)


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.
NOTES:


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


Generic scan tools may not read the codes listed, or may read only 5-digit codes. Match the 5 digits from the scan tool to
the first 5 digits of the 7-digit code listed to identify the fault (the last 2 digits give extra information read by the
manufacturer-approved diagnostic system).


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


Check DDW for open campaigns. Refer to the corresponding bulletins and SSMs which may be valid for the specific
customer complaint and carry out the recommendations as required.

The table below lists all Diagnostic Trouble Codes (DTCs) that could be logged in the Headlamp Leveling Control Module

Steering Column Switches - Steering Column Switches - Overview
Description and Operation

OVERVIEW

The steering column multifunction switch is situated on the steering column and consists of the wiper switch, the turn signal
indicator/lighting switch and the trip computer switch.
The RH (right-hand) multifunction switch controls the following windshield wiper functions:
Flick wipe
Intermittent wipe
Slow speed wipe
High speed wipe
Wash/Wipe
Headlamp powerwash
Rain sensing / variable wipe selection.
The LH (left-hand) multifunction switch controls the following functions:
Turn signal indicators
Side lamps
Headlamps
Auto lamps
High/low beam
Headlamp flash
Headlamp timer
Trip computer.

The steering column adjustment switch is located in the steering column lower shroud on the LH side. The switch is a 4 position 'joystick' which controls reach and rake adjustment.

The trip button allows the driver to cycle though an option menu and also reset trip cycle mileage calculations. The trip
computer information is displayed in the instrument cluster message centre.

Steering wheel mounted switches on the LH side of the driver's airbag, control the audio and telephone functions. Switches on the RH side of the driver's airbag, control the speed control functions. The steering wheel has an internal heating element. This is controlled by the driver via the Touch Screen Display (TSD). www.JagDocs.com

LEFT HAND MULTIFUNCTION SWITCH

Turn Signal Indicators System Operation

The instrument cluster outputs a reference voltage to the turn signal indicator switch. When the switch is in the central off
position, the voltage flows through 3 resistors which are connected in series and back to the instrument cluster which monitors
the signal and determines the turn signal indicators are off. This information is broadcast on the medium speed CAN bus to the CJB.
When the switch is operated in the LH turn signal indicator position, the reference voltage from the instrument cluster is routed via 1 of the resistors. The returned signal voltage is detected by the instrument cluster which outputs a message on
the medium speed CAN bus to the CJB. The CJB activates the applicable turn signal indicators until it receives an off message from the instrument cluster.

When the switch is operated in the RH turn signal indicator position, the reference voltage from the instrument cluster is routed via 2 of the resistors. The returned signal voltage is detected by the instrument cluster which outputs a message on
the medium speed CAN bus to the CJB. The CJB activates the applicable turn signal indicators until it receives an off message from the instrument cluster.
Lighting Control Switch

The instrument cluster outputs 2 reference voltages to the rotary lighting control switch; one feed being supplied to the light
selection function of the switch and the second feed being supplied to the autolamp exit delay function. The switch position is
determined by instrument cluster by the change in returned signal voltage which is routed through up to 4 resistors in series
depending on the selection made.

When the lighting control switch is in the off position, the reference voltage flows through 1 of the resistors. The returned
signal voltage is detected by the instrument cluster which outputs a message on the medium speed CAN bus to the CJB that no lighting selection is made. The reference voltage to the autolamp exit delay switch is routed through 4 resistors which is
detected by the instrument cluster which outputs a message on the medium speed CAN bus to the CJB that autolamp or exit delay has not been selected.

When the lighting control switch is in the sidelamp position, the reference voltage flows through 2 of the resistors. The
returned signal voltage is detected by the instrument cluster which outputs a message on the medium speed CAN bus to the CJB to activate the sidelamps. The reference voltage to the autolamp exit delay switch is routed through 4 resistors which is detected by the instrument cluster which outputs a message on the medium speed CAN bus to the CJB that autolamp or exit delay has not been selected.

When the lighting control switch is in the headlamp position, the reference voltage flows through 3 of the resistors. The
returned signal voltage is detected by the instrument cluster which outputs a message on the medium speed CAN bus to the CJB to activate the headlamps. The reference voltage to the autolamp exit delay switch is routed through 4 resistors which is detected by the instrument cluster which outputs a message on the medium speed CAN bus to the CJB that autolamp or exit delay has not been selected.

When the lighting control switch is in the autolamp position, the reference voltage flows through 4 of the resistors. The
returned signal voltage is detected by the instrument cluster which outputs a message on the medium speed CAN bus to the CJB to activate the autolamp function. The reference voltage to the autolamp exit delay switch is routed through 4 resistors which is detected by the instrument cluster which outputs a message on the medium speed CAN bus to the CJB that autolamp has been selected.
Autolamp Exit Delay

When the lighting control switch is in any of the autolamp exit delay position, the lighting control switch reference voltage
flows through 4 of the resistors. The returned signal voltage is detected by the instrument cluster which outputs a message on
the medium speed CAN bus to the CJB that autolamps has been selected.
Depending on the selected position, the reference voltage to the autolamp exit delay switch is routed through 3, 2 or 1
resistors which is detected by the instrument cluster. The cluster outputs a message on the medium speed CAN bus to the CJB that autolamp exit delay period has been selected at 30, 60 or 120 seconds respectively.
Trip Function Button

The instrument cluster outputs a reference voltage to the trip function button. When the function button is pressed a ground

battery power supply to be passed via the slip ring assembly in the steering wheel to the heated steering wheel control
module. The steering wheel module supplies power to the steering wheel heater element and also monitors the temperature
via a NTC (negative temperature coefficient) temperature sensor incorporated into the heater element. The control module
varies the power supply to the element to maintain the steering wheel rim at the optimum temperature.
