Poor Radio Reception - Diagnosis of Antenna Amplifier Possible
Vehicle Type:
Boxster (986)/Boxster S (986)
Model Year:
2003 (3) to 2004 (4)
Equipment:
PCM2 (I No. 665)
Antenna amplifier antenna diversity (I No. 440)
Concern:
Diagnosis of antenna amplifier is now possible with PIWIS DVD ROM 6.0.
Information:
Investigations of antenna amplifiers replaced under warranty due to interference in radio reception have shown that almost all antenna amplifiers are fully functional.
Using the PIWIS Tester and installed test software version 6.0/11/2004 (or higher), an antenna amplifier diagnostic (antenna diversity test) is possible for more precise fault localization on vehicles with PCM2.
When diagnosing customer complaints regarding radio reception interference, you must first perform an antenna amplifier diagnostic (antenna diversity) test and if necessary, troubleshoot the condition according to the specifications of the PIWIS Tester (see "Work Procedure" section).
The antenna amplifier needs to be replaced only if the radio reception has not improved after troubleshooting and fault remedying have been performed. The associated vehicle analysis log needs to be included with faulty antenna amplifiers when submitting a warranty claim to the Atlanta Warranty Test Center.
Note:
PAG has also noticed that loudspeaker amplifiers returned under warranty are often coded using the Part ID of the antenna amplifier (Part ID 9184). Please make sure to use the correct component coding when returning:
- Part ID 9184: Antenna amplifier
- Part ID 9144: Loudspeaker amplifier (BOSE, Harman)
