Preparing For the 4LH SSC
Overview
Lexus is initiating a Special Service Campaign (SSC). The 4LH SSC is for 2004 RX 330s. On certain 2004 model year RX 330 vehicles, a silicon oxide
build-up occurs on the contacts inside the brake light switch which can make it inoperable. This bulletin provides all the details necessary to plan and
implement this SSC at your dealership. Key points on the SSC are summarized below.
4LH Condition
On certain 2004 model year RX 330 vehicles, a silicon oxide build-up occurs on the contacts inside the brake light switch which can make it inoperable.
If the switch is inoperable, the brake lights will not illuminate. In addition, there is a possibility that the ABS warning light may illuminate and/or the
vehicle may not shift out of the "P" (park) position.
4LH Repair
The SSC 4LH involves replacing the brake light switch.
Customer Notification
Notification letters will be sent to the owners of affected vehicles beginning in mid-December 2004. This letter will advise owners of the need to have
the brake light switch replaced.
