Vehicle Speed Sensor (VSS) Circuit Check: Esteem

Ensure ignition is off. Disconnect Cruise Control Electronic Control Unit (CC ECU) harness connector. Check for poor connection at CC ECU harness connector terminal No. 1 (Violet wire). See Figure . Repair as necessary. If connection is okay, go to next step.
Connect DVOM between CC ECU terminal No. 1 (Violet wire) and ground. Raise and support vehicle. Rotate left front tire with right front tire blocked. Ohmmeter should fluctuate between continuity and no continuity a few times during one full wheel revolution. If continuity is as specified, Vehicle Speed Sensor (VSS) circuit is okay. If continuity is not as specified, check VSS. See VEHICLE SPEED SENSOR (VSS) under COMPONENT TESTS. Replace VSS as necessary. If VSS tests okay, repair open or short in Violet wire to VSS. See WIRING DIAGRAMS .
