Safety Precautions
Issue 5, January 2010 Workshop Manual 0-0-7
Safety Precautions
All service workshops are a source of potential danger and
repair work should only be performed by technically trained
staff following procedures detailed in this manual. A safety
conscious approach to the performance of all service
procedures must be observed at all times. Statutory
requirements governing all aspects of health and safety at
work including directives for the proper use of materials and
equipment must be implemented.
The following contains a list of particular safety precautions
which should be observed; it is not intended to be
exhaustive.
Battery Disconnection
When a service manual procedure requires the vehicle
battery to be disconnected - always physically disconnect
the vehicle battery earth (Negative) lead.
Do not use the ‘Battery Disconnect Switch’.
After reconnecting the vehicle battery the following items
will have to be reset or re-learnt:
•Radio pre-sets
•Windows
• DTCs will be lost
Air Conditioning (A/C) System
Do not break into the A/C refrigeration system until the
refrigerant has been evacuated using the procedure detailed
in this manual. Do not disconne ct any A/C refrigerant system
pipes unless trained and instructed to do so. The refrigerant
used can cause blindness if allowed to contact your eyes.
Chemical Handling and Storage
Chemicals used in the servicing of motor vehicles include
acids, adhesives, antifreeze, brake fluids, coolants, grease,
oil, paint, resin and solvents. Exposure to certain chemicals
through direct contact or inhalation can be fatal.
Potential hazards may also be present through the incorrect
use, storage and handling of chemicals causing a fire risk.
The following precaution s should be observed.
• Strictly adhere to handling and safety information found on containers and labels.
• Do not store chemicals in unlabelled or incorrectly labelled containers.
• Containers used for storing chemicals should not be left open; there is a risk of spilling , or evaporation of fumes
which may be inflammable or toxic.
• Do not mix chemicals unless instructed to do so following manufacturers guidelines.
• Do not inhale chemical materials to determine identity, they may be toxic.
• Do not use petrol, kerosene, diesel fuel, gas oil, thinners or solvents for washing skin.
• Containers whose capacity is over 25 litres (5 gallons) require a bund wall in order to contain spillages. • Chemicals based on solvents such as paint should not be
sprayed in a confined space; work areas used for such
operations should be well ve ntilated and fume extraction
equipment should be utilised.
• Ensure that adequate ventilation is provided when volatile de-greasing agents are being used.
• Avoid splashing the skin, eyes and clothing .
• Clean chemicals from the skin and clothing as soon as
possible after soiling .
• Wear protective clothing such as goggles, non porous gloves and apron when handling battery acid and other
corrosive and toxic substances.
Electrical Equipment
• Ensure that electrical equipment is in safe working order before use.
• Inspect power leads of all mains electrical equipment for damage and security, and check that it is properly earthed.
• Ensure that electrical equipment is protected by a fuse of the correct current rating .
• Disconnect the battery before commencing repair operations to the electrical sy stem, fuel system and engine
or when working beneath the vehicle.
Exhaust Fumes
Engines should not be run in confined spaces as exhaust
fumes contain harmful and to xic substances including
carbon monoxide which can prove fatal if inhaled. Engines
must only be run where there is fume extraction equipment
in operation or where there is adequate ventilation.
Fire Precautions
• Ensure that a suitable form of fire extinguisher is conveniently located near the work area.
• Keep oils, solvents and combustible materials away from naked flames and other sources of ignition.
• Ensure that NO SMOKING signs are posted around areas where combustible materials and vapour may be present
and ensure that the warnings are strictly observed.
• Ensure that dry sand is availabl e to soak up any spillage of
fuel or other flammable solutions.
• Fume extraction equipment must be available and in full working order to remove combustible and toxic vapours.
• All personnel should be aware of the fire drill procedures and precautions. WAR NI NG
DO NOT SMOKE IN THE VICINITY OF VOLATILE DE- GREASING AGENTS.
WAR NI NG
FUME EXTRACTION EQUIPMENT MUST BE IN
OPERATION WHEN SOLVENTS ARE USED E.G. TRICHLOROETHANE, WHITE SPIRIT, SBP3,
METHYLENE CHLORIDE, PERCHLORETHYLENE.

Battery System (14.01)
Power Supply (14.00)14-1-2 Workshop Manual May 2007
Power Supply (14.00)
Battery System (14.01)
Description
The 12 volt negative earth (‘-’ ve) battery is located under the RH side rear seat and is grounded to the vehicle body.
The battery positive (‘+’ ve) terminal is connected to a battery connect switch. The connect switch may be accessed by
raising the rear seat cushion.
Battery Connect Switch
When the battery connect switch is in an ‘open’ state it
isolates electrical power from all systems except the ‘keep
alive memory’ functions in the PCMs, TCU, radio,
navigation system and door modules.
This function isolates electri cal power from vehicle circuits
under all normal service conditions with the following
exceptions:
• Before any welding or other work which may induce high voltages into the electronic control modules
• Before disconnecting any of the control modules with ‘keep alive memory ’
• Before any major service task (e.g . engine removal)
• Before installing any accessory which involves modification of vehicle wiring
In the above four exceptions the battery earth (‘-’ ve) lead
should be disconnected.
When the battery earth (‘-’ ve) terminal is disconnected,
data held in keep alive memories will be lost. After connecting the battery, the radio preset stations and the
door window controllers will require to be reset (adaptive
learning data in the PCM module will require to be re-
learned by driving the vehicle for some miles in a range of
driving conditions),
driveability may be slightly
compromised until the vehicle systems have completed
their adaptive learning routines again.
Battery Disconnection and Alarm
Activation
The vehicle is installed with an alarm which will be activated
if the battery is disconnected. This alarm is driven by a back
up battery within the alarm sounder unit.
To prevent the alarm from so unding when the battery is
disconnected (for workshop procedures), disconnect the
battery within 10 seconds of switching off the ignition.
Always carry out the following procedures upon connection
of the battery.
• Reset the clock
• Reset the radio preset programmes.
• Reset the window maximum up and maximum down settings.

AML EOBD System Operation Summary

Rory O’Curry Aston Martin Lagonda CONFIDENTIAL 1 May 2009
[email protected] AML EOBD Monitors 07 ROC.doc Page 3 of 43

Introduction


This document describes in detail the operation of the AML (Aston Martin Lagonda) EOBD System.

The AML EOBD System consists of a series of Mon itors designed to observe the operation of strategic
aspects of the Emission Control System. For each of the Monitors there is a detailed functional review of
the monitor's operation, a listing of the relevant malfunction codes, typical Monitor entry conditions
followed by typical malfunction thresholds.

The AML EOBD System also incorporates a Malfunction Indicator Lamp or MIL (symbol shown on the
last page). The MIL will only be used to report emi ssion related failures and to indicate emergency start-
up or Limp Home routines. It will not be used for any other purpose.

Although this document describes all the Monitors cont ained within the AML EOBD System, not ALL of
these monitors may be utilised on every vehicle built w ith the AML EOBD System. This is primarily due
to the hardware configuration of the particular vehicle in question e.g. Auto vs. Man Transmission OR
EGR vs. No EGR. Please refer to the vehicle specific documentation for details of those Monitors that will
be operational.

It is important to note that to illuminate the MIL, th e failure condition must be observed at least twice. The
first occurrence will set a 'pending code' and the second occurrence will illuminate the MIL. The only
exception to this is the Type A Misfire failure, whic h will 'flash' the MIL at the first occurrence of the
failure condition. Therefore, if an OBD reset is performed, a minimum of two trips is required to
illuminate the MIL, although the Misfire Monitor does require pre-conditioning to learn 'Profile
Correction' and will utilize three trips.

De-activation of the MIL can be achieved if, no furt her separate failure conditions are detected and 3
subsequent and sequential trips have been comp leted where the original failure condition which
illuminated the MIL initially, is no longer detected.

The MIL code will be completely erased if the same failure condition is not detected after 40 trips.

deviant accelerations of this type are considered noise. Noise-free deviant acceleration exceeding a given
threshold is labeled a misfire.

The number of misfires are counted over a continuous 200 revolution and 1000 (or 4000)
revolution period. (The revolution counters are not reset if the misfire monitor is temporarily disabled such
as for negative torque mode, etc.) At the end of the evaluation period, the total misfire rate and the misfire
rate for each individual cylinder is computed. The misfire rate evaluated every 200 revolution period
(Type A) and compared to a threshold value obtaine d from an engine speed/load table. This misfire
threshold is designed to prevent damage to the cat alyst due to sustained excessive temperature. If the
misfire threshold is exceeded and the catalyst temperature model calculates a catalyst mid-bed temperature
that exceeds the catalyst damage threshold, the MIL blinks at a 1 Hz rate while the misfire is present. If the
threshold is again exceeded on a subsequent driving cy cle, the MIL is illuminated. If a single cylinder is
indicated to be consistently misfiring in excess of the catalyst damage criteria, the fuel injector to that
cylinder may be shut off for a period of time to pr event catalyst damage. Up to two cylinders may be
disabled at the same time. This fuel shut-off feature is used on many 8-cylinder engines. It is never used
on a 4-cylinder or 6-cylinder engine. Next, the misf ire rate is evaluated every 1000 (or 4000) rev period
and compared to a single ( Type B ) threshold value to indicate an emission-threshold malfunction. If a
1000 rev period is calibrated, a single 1000 rev exceedence from startup or four subsequent 1000 rev
exceedences on a drive cycle after start-up is used as the malfunction criteria. If a 4000 rev period is
calibrated, a single 4000 rev exceedence is used to indicate an emission-threshold malfunction.





Misfire Monitor Operation :
DTCs P0300 to P0312, P316 ,P1309, P1310, P1311
Monitor execution Continuous, misfire rate calculated every 200 and 1000 or 4000 revs
Monitor Sequence none
Sensors OK CKP, CMP, ECT
Monitoring Duration Entire driving cycle ( see disablement conditions below )

Typical misfire monitor entry conditions Minimum Maximum
Time since engine start-up 5 seconds
Engine Coolant Temp 20 oF 250 oF
RPM Range idle as per Directive
Profile correction factors learned in KAM Yes

Misfire Monitor temporary disablement conditions ( other than entry requirements )
Closed throttle decels (negative torque, engine being driven)
Engine Torque Reduction Modes
Accessory load-state change (A/C, power steering)
EGR Monitor Flow Test

Typical misfire monitor malfunction thresholds :
Type A (catalyst damaging misfire rate) misfire rate is an rpm/load table ranging from 40% at idle to
4% at high rpm and loads.
Type B (emission threshold rate) 1% to 5%

Inspection Maintenance Readiness Code


I/M readiness information indicates whether a full diagnos tic check has been completed, i.e. the minimum
number of driving cycles necessary for MIL illumination has been completed since computer memory was
last cleared. Information available to the test equi pment or diagnostic tool includes all the non-continuous
monitors. Misfire, Fuel System and CCM monitors are assumed to complete if all the non-continues
monitors have completed.

A P1000 DTC is stored after an OBD reset is performed, until the I/M readiness check is complete.



Tamper Protection


The AML EOBD System shall meet ISO DIS 15031-7 / SAE J2186 - Diagnostic Data Link Security
requirements, to write-protect any re-programmable co mputer code. Additional data will be stored in the
PCM Vehicle Identification Block to enable retrieva l of VIN (although VIN may not be in the VID block
for all vehicles), CALID (CALibration ID identifi es the specific calibration) and CVN (Calibration
Verification Number, similar to an encrypted check sum). CALID and CVN will be tracked for all initial
releases, running changes and field fixes.

To achieve this data retrieva l J1979 Mode 09 will be implemented for VIN, CALD and CVN.



Serial Data Link Connector

The connection between the vehicle and the diagnostic tester shall comply with ISO DIS 15031-3 / SAE
J1962. Whereby the connector will be located in the passenger compartment in the area bounded by the
driver's end of the instrument panel to 300mm beyond the vehicle center line, attached to the instrument
panel and accessible from the driver's seat, and permit one handed / blind insertion of the mating
