SYMPTOM/CONDITION:
The customer may describe when changing the radio tone settings (Bass, Mid, Treble) the
volume levels may be erratic. Depending where the volume is set, the volume changes
maybe very loud or very little. Example: Volume set to 8 and making adjustments to the
tone settings, the volume can increase by 15 db. Volume set to 25 and making
adjustments to the tone settings, there maybe no volume changes.
DIAGNOSIS:
Using a Scan Tool (wiTECH) with the appropriate Diagnostic Procedures available in
TechCONNECT, verify if any Diagnostic Trouble Codes (DTCs) are set. If DTCs or
symptom conditions are present, record the issues on the repair order and repair as
necessary before proceeding further with this bulletin.
If the customer describes the symptom/condition listed above, perform the Repair
Procedure.
REPAIR PROCEDURE:
NOTE: Install a battery charger to ensure battery voltage does not drop below 13.2
volts. Do not allow the charging voltage to climb above 13.5 volts during the
flash process.
NOTE: In some cases the part number may update before the flash has been
completed. If this flash process is interrupted/aborted, the flash should be
restarted, even if the part number did update.
1. Reprogram the AMP with the latest available software. Detailed instructions for
flashing modules using the wiTECH Diagnostic Application are available by selecting
the “HELP” tab on the upper portion of the wiTECH window, then “HELP CONTENTS.”
This will open the Welcome to wiTECH Help screen where help topics can be
selected.
NOTE: If the flash failed an active DTC may set, B1488-00 Cabin EQ Mismatch
Performance. Reflashing the AMP will change the DTC status from active to
stored and then the DTC can be cleared.
2. Clear any DTCs that may have been set in any modules due to reprogramming. The
wiTECH application will automatically present all DTCs after the flash and allows them
to be cleared.
POLICY:
Reimbursable within the provisions of the warranty.
