Inspection Procedure

    NOTE: When the battery positive voltage is applied to the motor connector terminals, (+) and (-) are interchangeable.
  1. Disconnect the connector of the sensor and the connector of the motor leading to the sensor. Connect the positive (+) lead to terminal No. 3 of the sensor and negative (-) lead to terminal No. 2. See CONNECTOR IDENTIFICATION . Measure the voltage between terminal No. 1 of the sensor and body ground when battery voltage is applied between terminals No. 1 and 2 of the motor connector. See INSPECTING POSITION SENSOR VOLTAGE  table. If the results are OK, go to the next step. If the results are not good, replace the position sensor. See POWER SEAT  under REMOVAL & INSTALLATION.
