Steering Wheel Airbag Rattle
SRO: 01.20.CJ
Safe VINs: DBS - E01082, V8 Vantage - D13104, DB9 - A12179
Repair:
1. Put the Emotion Control Unit (ECU) into the docking station at position 2 to release the Electronic Steering
Column Lock (ESCL)
2. Disconnect the battery (refer to Workshop Manual procedure 14.01.CA).
WARNING:
WAIT FOR TWO MINUTES BEFORE YO U CONTINUE WITH THIS PROCEDURE. THIS IS TO MAKE SURE
THAT THERE IS NO POWER TO TH E AIRBAG SYSTEM. IF YOU DO NOT DO THIS, THE AIRBAG CAN
OPERATE SUDDENLY AND CAUSE INJURY
WARNING:
BE CAREFUL WHEN YOU HOLD AND MOVE THE AIRB AG UNIT. THE AIRBAG UNIT HAS AN EXPLOSIVE
CHARGE IN IT. IF YOU DO NOT HOLD THE UNIT CAREFULLY, THE CHARGE CAN OPERATE AND CAUSE
INJURY.
3. Turn the steering wheel to get access to the screws that attach the driver's airbag to the steering wheel.

Figure 1
4. Remove the screw that attaches the driver's airbag to the steering wheel.

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 8 of 43
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 temporary disablement conditions ( other than entry requirements )

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%
