NOTE: This bulletin applies to **W2, W3,** WD, WK vehicles built on or before September 08, 2015 (MDH 0908XX) equipped with 9 Amplified Speaker W/Subwoofer (Sales Code RC3).
NOTE: This bulletin applies to LA, LD, LX vehicles built on or before August 11, 2015 (MDH 0811XX) equipped with 276 Watt Amplifier (Sales Codes RD7) or 506 Watt Amplifier (Sales Codes RFD).
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 may be very loud or very quiet. Example: When the volume is set to 8 and making adjustments to the tone settings, the volume can increase by 15 db. When the volume is set to 25 and making adjustments to the tone settings, there maybe no volume changes.
**The customer may also describe when listening with the volume set to 9 there is more bass and less mid/high. When the volume is set to 10 is less bass and more mid/high (WD,WK, W2 and W3 only).**
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.
- 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.
- 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.

FAILURE CODE:
The dealer must choose which failure code to use. If the customer came in with an issue and the dealer found updated software to correct that issue, use failure code CC, for all other use failure code RF.
- If the customer’s concern matches the SYMPTOM/CONDITION identified in the Service Bulletin, failure code CC is to be used.
- If an available flash is completed while addressing a different customer concern, failure code RF is to be used.

- POWER: Maximum Power Output of 1500 Watts at 2 Ohms into one channel. MAX Power Output of 750 Watts at 4 Ohms into one Channel. This amplifier is designed to run your subwoofer(s) giving them the power that they need to perform as they were meant to
- HIGH LEVEL INPUTS: Speaker level inputs are commonly referred to as high-level inputs. Speaker level inputs will be used to connect the AR1500M to your factory radio or an aftermarket radio that does not have low-level (RCA) inputs
- LOW LEVEL INPUTS: Line level inputs, also known as RCA inputs or low-level inputs, use RCA interconnect cables to link the AR1500M with the source unit. Most aftermarket radios have multiple pairs of RCA outputs that can connect to multiple amplifiers
- LOW-PASS CROSSOVER: A low-pass filter is an electronic circuit that removes all the notes below the filter's frequency setting. You will use the Low-pass filter to primarily keep high notes out of your subwoofer(s)
- SWITCHABLE BASS BOOST: Switchable Bass Boost allows you to boost the low bass +18db.
