Many Lexus vehicles can store more than one set of TPMS ID’s in ECU. Toggle the
vehicles selected set to the MAIN set. Then retry OBDII Relearn.
Error E5 ‐ Spare Tire Error

About Lexus GX470
The GX 470 hasn’t changed too much since it was introduced in 2003. This year, it receives a few new exterior colors and some updates to interior items like the parking brake handle.
The second-generation GX debuted at the 2009 Auto Guangzhou Motor Show in China on the last week of November 2009. The new model, dubbed GX 460 sees a reduction in the displacement of its powerplant from 4.7 to 4.6 litres as a result of getting Toyota’s new 4.6-liter V8 engine from the Tundra that makes 310-horsepower and 327 lb.-ft. of torque. That’s 47 hp and 4 lb-ft. of torque more over the old 4.7 mill. The new GX is based off of the new Toyota Land Cruiser Prado and is set to go on sale in early 2010. The new car was designed under global design manager Simon Humphries. (About Wiki Cars)
