WARNING: This page is about a different car, the 2002 Lexus ES 300. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: If the ignition switch is turned from ON to ACC or LOCK position during test mode, DTC of sensor check function will be erased. During test mode, ECU records any DTC set during sensor check function. By performing sensor signal check, the codes are erased if normal operation is confirmed. Any DTCs still stored are the DTCs where malfunction was found.

NOTE: When ABS warning light is always on hand-held tester cannot be used.
