Test M: Speed Sensor Signal Check: Notes

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 during test mode, DTC of sensor check function will be erased. During test mode, ABS/TRAC control module (or skid control ECU) records all DTCs of sensor check function. By performing sensor signal check, the codes are erased if normal condition is confirmed. The codes left over are the codes where abnormal condition was found.

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