SERVICE INFORMATION

The microphone circuit of the Lexus LS 400 command module has been modified to improve phone performance in the "hands-free" mode. The modification results in a 4 dB gain increase. This new command module replaces the old command module (no longer in production).

The new command module can be identified by the presence of a serial number tag on the back surface of the module. See Fig 1. The old module does not have a serial number tag.
