With the control valve (7) OPEN and the engine idling, the following system pressures may be checked:
During turning when static (dry parking pressure).
When the steering is held on full lock (maximum system pressure or pressure relief).
With the steering at rest (idle pressure or back pressure).
CAUTIONS:
To avoid excessive heating of the power steering pump when checking the pressure, do not close the valve for more than
5 seconds maximum.
When checking the pump pressure DO NOT drive the vehicle with the test equipment installed.
With the control valve (7) CLOSED the power steering pump maximum output pressure can be checked.
Removing Test Equipment
To remove the test equipment:
Install a hose clamp on the reservoir to power steering pump hose.
Removing the test equipment is a reversal of the installation instructions.
Install a new 'O' ring seal (9) to the power steering pump high pressure outlet to hose connection.
Install the original hose to the power steering pump.
Remove the clamp from the reservoir to the power steering pump hose.
Top-up the reservoir fluid.
Bleed the power steering system.

WARNING: Fuel injector voltage will reach 65Volts during operation and have a high current requirement.
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 module/component is suspect and the vehicle remains under the Manufacturers warranty, refer to the Warranty
Policy and Procedure manual (section B1.2), 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 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.
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.

The functionality for each of the above warning indicators is described in the following sections:
1 and 2. Turn Signal Indicators
The turn signal indicators are controlled by the CJB on receipt of medium speed CAN bus signals from the instrument cluster.
The instrument cluster outputs a voltage to the turn signal indicator switch. The switch contains resistors of different values.
When the switch is operated in either the LH or RH direction, the voltage is passed to a ground connection in the instrument cluster which detects the reduced voltage supplied via the resistors. When the turn signal indicator switch is operated in the
LH or RH direction, the instrument cluster detects the ground voltage and determines whether a LH or RH selection is made.
The instrument cluster transmits a medium speed CAN message to the CJB for operation of the applicable turn signal indicators. The message can contain a number of states for each possible switch position and also an out of range low and
high state for circuit faults and an initial value for the switch neutral position. The turn signal indicators are not subject to the
3 second indicator check when the ignition is switched on.
The RJB (rear junction box) software controls the flash rate of the warning indicator which sends 'ON' and 'OFF' signals to the
instrument cluster which flashes the indicators in a green color. During normal operation, the warning indicator flashes slowly,
accompanied simultaneously by a sound from the instrument cluster sounder. If a fault exists, the RJB transmits a message to the instrument cluster which responds by displaying an appropriate message in the message center.
The hazard warning indicators are controlled by the CJB on receipt of a completed ground path from the hazard warning indicator switch. The CJB outputs a medium speed CAN message to the instrument cluster which operates both the LH and RH turn signal indicators simultaneously. The hazard warning indicators can operate with the ignition switched off, therefore the
CAN message from the CJB will also carry a 'wake-up' message for the instrument cluster. 3. Brake Warning Indicator
This warning indicator is displayed in a red or amber color (dependant on market) as a brake symbol in all markets except
United States of America (USA) which have the word 'BRAKE' in place of the symbol. The indicator is controlled by high speed
CAN messages from the ABS module and the parking brake control module. The indicator is illuminated in a red color for a 3 second indicator check when the ignition is switched on.
The instrument cluster monitors the fluid level in the brake fluid reservoir using a hardwired level switch. If the fluid level falls
to below a determined level, the switch contact is broken and the ABS module detects the low fluid level condition. The instrument cluster illuminates the warning indicator and simultaneously displays a 'BRAKE FLUID LOW' message in the
message center.
NOTE: If both the brake warning indicator and the ABS warning indicator illuminate simultaneously, a major fault in the brake system will have occurred.
The warning indicator also displays parking brake status. When the parking brake is applied, the warning indicator will be
illuminated by the instrument cluster and, if the vehicle is moving, the message 'PARK BRAKE APPLIED' will be also displayed
in the message center in response to a CAN message from the parking brake control module.
If a condition exists where the parking brake cannot be applied, the parking brake control module issues a CAN message to the instrument cluster which flashes the warning lamp on and off and is accompanied with a message 'CANNOT APPLY PARK BRAKE'.
If a fault occurs in the parking brake system, the parking brake control module issues a CAN message to the instrument cluster which illuminates the warning indicator and displays the message 'PARK BRAKE FAULT' in the message
center.
4. Forward Alert Indicator
The forward alert system uses the components of the adaptive speed control system to alert the driver of the presence of a
vehicle ahead. The system can be turned on and off using a switch located in the auxiliary lighting switch when the adaptive
speed control system is off. The indicator is illuminated in an amber color for a 3 second indicator check when the ignition is
switched on.
The forward alert system is controlled by the adaptive speed control module. When the switch is pressed, the forward alert
system is activated and the adaptive speed control module issues a forward alert active message on the high speed CAN bus to the instrument cluster. The forward alert icon in the instrument cluster will illuminate in an amber color and a 'FORWARD
ALERT' message will be displayed in the message center. When the button is pressed a second time, the module issues a
forward alert off CAN message. The forward alert system will be deactivated, the forward alert icon will go off and a message 'FORWARD ALERT OFF' will be displayed in the message center.
5. Automatic Speed Limiter (ASL) Indicator
The ASL is controlled by the ECM (engine control module). An ASL switch is located in the floor console, adjacent to the gear
selector lever. When the ASL switch is pressed, this is sensed by the ECM which issues a high speed CAN message to the instrument cluster. The instrument cluster illuminates the ASL warning indicator in an amber color to show the driver that ASL
is active. The driver sets the required speed using the speed control SET +/- switches on the steering wheel. The selected
speed is shown by the message ' LIMITER SET XXX MPH / K/MH' in the message center. The indicator is illuminated in an
amber color for a 3 second indicator check when the ignition is switched on. ASL can be deselected by pressing the ASL switch,
by depressing the throttle pedal initiating kick-down or by pressing the 'cancel' switch on the steering wheel. The ASL indicator
will go off and the message center will display the message 'limiter cancelled' for 4 seconds. If a fault occurs in the ASL
system, the ECM will send a message to the instrument cluster to illuminate the ASL indicator and display the message 'LIMITER NOT AVAILABLE'.
