TSB EL006-04 / Instruments - Multi-Display Functions are Inoperative

Title:
MULTI-DISPLAY FUNCTIONS
ARE INOPERATIVE

Models:
'04 LS 430 & LX 470

December 14, 2004

Introduction
Some customers may experience various malfunctions occurring with the multi-display. Some examples are:
^ "Audio Off" is shown on audio screen while audio system is playing.
^ Climate control is not responsive and may say "Check connection of the air conditioner."
^ Map, Destination buttons are inoperative and may display "External system not connected."
^ When pressing any button on the multi-display, the system takes 5 to 10 seconds to respond to the user's input.
^ Outside air temperature is not displayed.

A revised multi-display has been developed to resolve these conditions.

NOTE :If the TX+ or TX- wires are loose at the multi-display, the same symptoms will occur.

Please confirm that all connections at the multi-display are secure and that pin fit of the TX+ and TX- wiring is good before ordering a replacement multi-display.
Applicable Vehicles
^ 2004 model year LS 430 and LX 470 vehicles equipped with the Lexus navigation system.

I started experiencing these issues for the past month or so, and I finally took it into the dealership to get taken care of. Thankfully my Lexus extended warranty covered this 100%, and things are working great now.

Just thought I'd post some info on this for anyone that might have some similar symptoms.
