REPLACEMENT GUIDELINES
This TSB supercedes TSB-04-54-002, issued February 2004, to include speaker locations on the Speaker Complaint Checklist and a new warranty
statement requiring Checklist submittal. Revisions are indicated by -->.
PURPOSE
This bulletin contains troubleshooting steps for diagnosing various customer complaints relating to the audio system speakers in Mitsubishi vehicles.
BACKGROUND INFORMATION
Symptom/Condition
You may receive customer complaints about abnormal noise from the audio system speakers. These can be described as any of the following:
^
Static
^
Popping
^
Crackle
^
Buzzing
^
Rattle
^
Distorted sound
^
Poor sound quality
^
No sound (speaker inoperative)
Proper diagnosis of speaker or speaker related conditions is important for customer satisfaction and correct warranty reporting. Some of these reported
abnormal sounds, which are often attributed to the speakers, may have other origins. Speakers are often replaced without the actual problem being
solved. In some cases, supposedly faulty speakers returned for warranty have been checked by the speaker manufacturer with no problem found. Make
sure the suspected speaker is carefully evaluated before replacement. Use the troubleshooting procedures represented in the three flowcharts in this
bulletin to help diagnosis speaker related conditions.
CHECKLIST REQUIRED
If warranty speaker replacement is required, the SPEAKER COMPLAINT CHECKLIST at the end of this bulletin MUST be completed and attached to
the replaced speaker and held until the subsequent request for return is issued. Make copies of the Checklist and use it each time warranty speaker
replacement is required.
--> Failure to submit the completed Speaker Complaint Checklist subjects the claim to debit.
AFFECTED VEHICLES
All Mitsubishi models and model years
