Speed Sensor Signal Check

NOTE: Information for clearing speed sensor diagnostic codes is not available from manufacturer. It may be possible to clear these codes by disconnecting battery cable or by using procedure for CLEARING DIAGNOSTIC TROUBLE CODES (DTC) .
  1. Turn ignition off. Using a fused jumper wire or Service Connector (SST 09843-18020), connect Data Link Connector No. 1 (DLC1) connector terminals Ts and E1. See Figure. DLC1 is located in engine compartment, right side of intake manifold next to fire wall. Start engine. ABS warning light should blink once every .13 second. If ABS warning light does not blink, check ABS warning light circuit. See ABS WARNING LIGHT CIRCUIT .
  2. Drive vehicle at 28 MPH or greater for several seconds in a straight line. Stop vehicle. Using another fused jumper wire or Service Connector (SST 09843-18020), connect DLC1 connector terminals Tc and E1. There should now be 2 jumper wires. See Figure.
  3. Observe ABS warning light. If system is normal, ABS warning light will blink every .25 second. If system is malfunctioning, ABS warning light will flash codes. See SPEED SENSOR DIAGNOSTIC CODE IDENTIFICATION . Repair as needed. Turn ignition off. Remove fused jumper wires or Service Connectors (SST 09843-18020), from DLC1 connector.
