Squeaks and Rattles Repair Manual

Squeak and Rattle Terminology
Squeaks
CHIRP High-pitched rapidly repeating sound, like chirping birds.
CREAK Metallic squeak, like the back of a seat flexing.
GRIND Abrasive sound, like a grinding wh eel or sandpaper rubbing against wood.
GRAUNCH Metallic abrasive sound, like two cast components rubbing together.
SQUEAK High-pitched sound, like rubbing a clean window.
TICK Audible rhythmic tap – clock noise.
Rattles
BRUSH Swish sound as contact parts touch lightly.
BUZZ Low-pitched sound, similar to a bee. Usually asso ciated with vibrations. Often metallic or hard
plastic humming.
CHATTER Rapidly repeating metallic sound.
CHUCK Rapid noise that sounds like a stick against the spokes of a spinning bicycle wheel.
CLICK light sound, like a ball point pen being clicked.
CLINK Usually a high frequency sound, like a sharp hard input to ceramic or glass.
CLANK Usually a mid-frequency. A sharp, hard, metallic knock.
CLUNK Usually a low-frequency, heavy sound, like something stressed being released under pressure.
DING Ringing noise like a bell.
HUM Continuous sound of varying frequencie s, like a wire humming in the wind.
KNOCK Heavy, loud, repeating sound like a knock on a door.
OIL CANNING Metallic "in/out" noise from metal surfaces reboundi ng in response to forced input like slamming
doors/hood.
PING Similar to knock, but at higher frequency.
RATTLE A sound that suggests looseness, such as marbles rolling around in a can.
SLAP Resonance from flat surfaces (seat belt webbing or door trim panels).
TAP Light hammering sound like tapping pencil on ed ge of table. Can be rhythmic or intermittent.
THUMP/THUD Dull beat caused by two items striking together.
TIZZ Rapid low-pitched diminishing sound often a secondary loose vibration after an impact.

Electronics Training Programme
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.
