Using the WDS or Equivalent NOTE: PIDs for the following parts are not available on this model. Go to the appropriate part inspection page. Main (See RELAY INSPECTION.) 1. Connect the WDS or equivalent to the DLC-2. 2. Turn the ignition to ON position. 3. Measure the PID value. If PID value is not within the specification, follow the instructions in Action column. NOTE: The PID/DATA MONITOR function monitors the calculated value of the input/output signals in the PCM. Therefore, an output device malfunction is not directly indicated as a malfunction of the monitored value for the output device. If a monitored value of an output device is out of specification, inspect the monitored value of the input device related to the output. For input/output signals except those of the monitoring items, use a voltmeter to measure the PCM terminal voltage.
