Yaw Rate Sensor

WARNING: This page is about a different car, the 2000 Toyota Land Cruiser and 2000 Lexus LX 470. However, it is still accessible from the selected car via links, so may be relevant.
  1. Turn ignition off. Remove ABS/BA/TRAC/VSC ECU, located behind left side of dash. Do not disconnect harness connectors. Using a DVOM, check continuity between yaw rate sensor harness connector terminal No. 4 (Blue wire) and ABS/BA/TRAC/VSC ECU harness connector A43 terminal No. 19 (Blue wire). See WIRING DIAGRAMS . If continuity does not exist, repair circuit as necessary. If continuity exists, go to next step.
  2. Backprobe DVOM positive lead to ABS/BA/TRAC/VSC ECU harness connector A43 terminal No. 19 (Blue wire) and negative lead to ECU harness connector A41 terminal No. 31 (White/Black wire). Turn ignition on. If voltage reading is 4.5-5.3 volts, replace ABS/BA/TRAC/VSC ECU. If voltage reading is not 4.5-5.3 volts, replace yaw rate sensor.
