## Not Using the WDS or Equivalent

  Note

  • The PCM terminal voltage can vary with conditions when measuring and changes due to age deterioration on the vehicle, causing false diagnosis. Therefore a comprehensive inspection of the input and output systems, and the PCM is necessary to determine where the malfunction occurs.

## Using the WDS or Equivalent

  Note

  • PIDs for the following parts are not available on this model. Go to the appropriate part inspection page.

  - CMP sensor (See CAMSHAFT POSITION (CMP) SENSOR INSPECTION [ZJ, Z6].)
  - Main relay (See RELAY INSPECTION.)

1. Connect the WDS or equivalent to the DLC-2.

2. Turn the ignition switch to the 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 control.
