Electric Antenna Malfunction In Cold Weather
On early 1992 900 and 9000 models the electric antenna may not power up in cold weather (below 40~F). The problem has been identified as a fault in
the radio head. It is not an antenna malfunction.
The remedy involves the exchange of a defective radio head with a new unit containing modified circuitry. PSI Service Directive 12/91-0158 explains
the exchange program that has been initiated to replace any affected radios that are in vehicles in dealer inventory. For in-service cars (cars that have
been retailed), the routine for the exchange of radios is the same as used for other Clarion exchange units (see pages 97-100) in the Warranty Policies &
Procedure Manual.)
See this bulletin for details on the exchange procedure, billing procedure and warranty information.
Lack of Bass Response In Rear Speakers
On all 1992 9000 models up through VIN N1016651, a complaint of poor sound quality or lack of bass output may be remedied by making a wiring
change to the rear speaker harness. The problem is located in the 6-pin connector at the rear speaker amplifier under the front passenger seat. If the
wiring in this plug is incorrect, the rear speakers will be out of phase and strong bass response will be limited.
This PSI has been identified as a Service Directive, meaning that affected cars should be corrected before delivery if possible, or at the next service
opportunity, regardless of whether there has been a customer complaint.
See PSI Service Directive 12/91-0162 for the repair procedure and correct wiring orientation. Some vehicles before the above mentioned VIN may have
been corrected at the ports-of-entry. Check the wire positions before making a repair.
