SEAT HEATER REPLACEMENT PROCEDURE (REVISED)
The seat heater replacement procedure for the LS400 has been changed as follows, to ensure improved durability and ease of serviceability.
- For replacement of the previous type seat heater, the installation procedure has been changed; also, for the new type seat heater installation procedure, there are changes in accordance with the above illustration. Please follow the replacement procedures provided in this Technical Service Bulletin.
- The new type seat heater had been supplied to be installed in a seat cover, so the seat heater alone could not be replaced. Therefore, in order to improve the serviceability, we have established a single supply part for the seat heater. Please follow the replacement procedure on the following.
