Using the M-MDS (Without Throttle Valve Actuator)

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, ZY, Z6].)

―  Main relay (See RELAY INSPECTION.)

1.  Connect the M-MDS 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.
