Premium audio amplifier bass function check and replace (SC15/03) Technical background An electrical link located inside the premium audio amplifier may have been omitted when this is the case the bass response of the system is reduced Remedy A test CD is used to check the audio system. Systems found to be out of specification will require a replacement audio amplifier. Cars previously tested as a result campaign SC14/06, launched prior to amplifier availability, will have resulted in, a blue campaign completion mark to the front face of the audio amplifier where the amplifier was found to be functioning correctly or If a vehicle was found to have a defective amplifier a red identification mark was applied to the front face of the audio amplifier. The marks can be viewed on the amplifier adjacent to the starter battery (see Figure 10). Therefore any vehicle in the applicable vin list that has a red mark on the audio amplifier or because the car did not have SC14/06 applied has no relevant mark, but is applicable to this campaign, will require this campaign (SC15/03)
