Testing & Diagnostics ~154 words
  1. Check Input Signal Circuit Turn ignition off. Disconnect ECM harness connector and combination meter harness connector. (Схема №1) Using an ohmmeter, check continuity between combination meter harness connector terminal No. 14 (Pink/Blue wire) and ECM harness connector terminal No. 29. If no continuity exists, repair open in Pink/Blue wire. If continuity exists, go to next step.
  2. Check Speedometer Operation Check speedometer operation. If speedometer does not function, disconnect VSS harness connector. Remove VSS from transaxle. Check resistance between VSS connector terminals. Replace VSS if resistance is not 250 ohms. If resistance is 250 ohms, go to next step.
  3. Set voltmeter on AC scale. Connect voltmeter to VSS connector terminals. Turn VSS pinion gear to generate voltage. Voltage should generate to about 0.5 volt. If resistance and voltage are not correct, replace vehicle speed sensor. If VSS unit is okay, repair ECM pin terminals and/or wiring harness connector.
