  2. Using special tool (09843-18020), jumper between terminals Ts and E1 of (DLC1). See Figure.
  3. Start engine and check that VSC warning light flashes. If VSC TRAC warning light does not flash, inspect VSC TRAC warning light circuit and Ts terminal circuit. See TEST N: VSC TRAC WARNING LIGHT CIRCUIT  and TEST K: TS TERMINAL CIRCUIT  .
  4. Check steering angle sensor by turning steering wheel either to left or right for 450° or more from stationary condition. Turn back to straight ahead.
  5. Check yaw rate sensor by shifting shift lever to Drive position and drive vehicle at approximately 3 MPH. Turn steering wheel either left or right 90° or more, and maintain 180° circular drive. Do not spin wheels. At end of turn, direction of vehicle should be within 175°-185° of start position.
  6. Stop vehicle. Shift to Park position and verify that VSC buzzer sounds for 3 seconds. If VSC buzzer sounds, sensor check is completed normally. If VSC buzzer does not sound, perform check again. If buzzer still does not sound, there is a malfunction in VSC sensor. Check for ABS related DTC. See RETRIEVING CODES  under SELF-DIAGNOSTIC SYSTEM.
  7. For DTCs of VSC, see Figure.
