The symbol for the screen is an oval with the wires that are
to be screened inside it. The letters ‘SCR’ define the screen.
Controller Area Network (CAN)
Controller Area Network (CAN) is the wiring between
intelligent modules of the vehi cle. This wiring carries the
electronic data around the vehicle allowing the various
modules and components to interrogate the network and
read their specific data signals.
There are 2 different speeds of network.
Low speed - Transmits at 125,000 bits per second. Mainly
for body controller systems such as seats and doors
High speed - Transmits at 500,000 bits per second. Mainly
for engine management and powertrain associated systems
such as ABS.
All wiring in the CAN is twisted. The twisted wires always
consist of one wire with a black trace in it for the negative
side and one with a brown trace in it for the positive.
High Speed CAN wire
Low Speed CAN wire
The symbol below shows a module or a component
connector with the pin numbers that have CAN wires
coming from them.
‘CAN LS+’ - Low speed CAN positive side
‘CAN LS-’ - Low speed CAN Negative Side
To aid identification of the different speed CAN’s in the
vehicle different colours of wi re have been used, e.g. the
Low Speed Volcano is GB twisted with GN, the High Speed
Volcano is RB twisted with RN.
There is attached on a separate page a list for wire colour
abbreviations and what colour they refer to.

INPUTS
The Bluetooth system relies on a number of signals it receives either from the car (via hard wiring) or
the users phone (via wireless Bluetooth communication network).
The Bluetooth system will only function if the us ers mobile phone has Bluetooth enabled and it is
‘paired’ to the car. For more information refer to the user’s guide for your mobile phone.

Screens
Some of the signals in and out of the Bluetooth modu le require screening to avoid interference being
picked up. A signal screen is a single wire running along side t he signal wire(s) which will absorb
electro magnetic interference (EMI).
The Bluetooth module on the V8 Vantage features only one screen so as to protect the signal from the
microphone. This screen wire is simply an earth but it is also used as a datum from which to reference
the microphone signal.
The Bluetooth module used on DB9’s features two screens. One is as on the V8 Vantage but is used
only as a screen (because the microphone signal from the amplifie r has two signal wires) and no
datum is required. The second screen on the module is used to screen the ‘Lineout’ signals to the
amplifier. As with the microphone scr een this wire is connected to earth.

AML EOBD System Operation Summary
Rory O’Curry Aston Martin Lagonda CONFIDENTIAL 1 May 2009
[email protected] AML EOBD Monitors 07 ROC.doc Page 27 of 43
Comprehensive Component Monitor - Engine
General Inputs
Analog inputs such as Ambient Air Temperature (P0072, P0073), Intake Air Temperature (P0112, P0113),
Engine Coolant Temperature (P0117, P0118), Cylinder Head Temperature (P1289, P1290), Mass Air Flow
(P0102, P0103) and Manifold Absolute Pressure (P0107, P0108) are checked for opens, shorts, or out-of-
range values by monitoring the analog -to-digital (A/D) input voltage.
Analog Sensor Check Operation:
DTCs P0072, P0073, P0112, P0113, P0117, P0118, P0102, P0103, P0107, P0108,
P1289, P1290
Monitor execution continuous
Monitor Sequence none
Monitoring Duration 5 seconds to register a malfunction
Typical analog sensor check malfunction thresholds:
Voltage < 0.20 volts or voltage > 4.80 volts
On Vehicles fitted with Cylinder Head Temperature (CHT ) Sensors, 'Fail Safe Cooling' can be applied if
the cylinder head temperature is too high. The P1299 DTC will be set under these conditions.
Loss of Keep Alive Memory (KAM) power (a separate wire feeding the PCM) results in a P1633 DTC and
immediate MIL illumination.
Loss or corruption of the Vehicle Identification (VID) Block in the PCM results in a P1639 DTC and
immediate MIL illumination.
Ignition
Electronic Ignition systems (Electronic Distributorless Ignition System - EDIS or Coil on Plug - COP)
systems are used on all applications.
The EDIS system, located in the PCM, processes the 36 (or 40) tooth crankshaft position signal to
generate a low data rate PIP signal to control a 4 or 6 terminal 'double-ended' coil pack. The 'double ended'
coils fire a pair of spark plugs simultaneously - one is on its compression stroke, the other on its exhaust
stroke. The COP system also uses the EDIS system in the same way as described above, however each
sparkplug has it’s own coil which is fired only once on the compression stroke.
The ignition system is checked by monitoring three ignition signals during normal vehicle operation:
Profile Ignition Pickup (CKP, commonly known as PIP), the timing reference signal derived from the crankshaft 36-tooth wheel and processed by the EDIS system. PIP is a 50% duty cycle, square
wave signal that has a rising edge at 10 ° BTDC.
Camshaft IDentification (CMP, commonly known at CID), a signal derived from the camshaft to identify the #1 cylinder
