Condition "D"

Turn ignition on. Operate vehicle at speed greater than 9.3 MPH (15 km/h) and monitor voltmeter output pattern. A one-pulse pattern indicates normal operation. If voltmeter shows a 2-pulse pattern, check speed sensor or steering angle sensor or related wiring harness. See AAS-8 in TROUBLE SHOOTING  . If voltmeter shows a zero-pulse pattern, check speed sensor or related wiring harness. See AAS-9 in TROUBLE SHOOTING  .
