Audio - Alternator Noise With Rear CD Changer
NO.
TSB-92-54-010
DATE
December, 1992
MODEL
1993 Diamante and 3000GT
SUBJECT:
AUDIO NOISE FROM THE ALTERNATOR
PURPOSE
This bulletin describes the cause and correction of an audio system alternator noise (high-pitched whining) heard on some 1993 Diamantes and 3000GTs
equipped with model RX-367 audio system AND rear CD changer.
CAUSE
On some 1993 Diamantes and 3000GTs, an alternator noise (high-pitched whining sound) may be heard from the audio system during Compact Disc
(CD) changer operation. The cause of this noise may be an incomplete ground inside the AM/FM receiver/tape player portion of the audio unit. The
noise is only present on vehicles equipped with model RX-367 audio system AND rear mounted CD player; it DOES NOT affect RX-367 audio systems
WITHOUT CD changer, or vehicles equipped with the model RX-366 audio system.
CORRECTION
To correct the noise on in-stock vehicles, ALL 1993 Diamantes and 3000GTs shipped from the Port Of Entry (POE) BEFORE NOVEMBER 16, 1992
(equipped with RX-367 audio system and CD changer) MUST have the AM/FM receiver/tape player portion of the audio system replaced. Vehicles
shipped from the Ports after November 16, 1992, have been corrected before shipment to the dealers. The exchange program for RX-367 audio units will
be administered by Mitsubishi Electronics America (MELA).
The remainder of this bulletin describes RX-367 audio system identification, exchange program instructions, and warranty information.
AUDIO SYSTEM IDENTIFICATION
To identity the RX-367 audio system, look at the face of the AM/FM receiver/tape player; the radio station preset buttons are located on the bottom row
of the controls. On the RX-366 audio system (also used on some 1993 Diamantes and 3000GTs), the radio station preset buttons are located in the
middle row of the controls.
Refer to the illustration.
EXCHANGE PROGRAM INSTRUCTIONS
NOTE:
Each dealership should designate one person (such as the service manager or shop foreman) to oversee the exchange program.
To receive exchange units from MELA, follow these instructions:
