Without Using the M-MDS

Caution

• The PCM terminal voltages vary with change in measuring conditions and vehicle conditions. Always carry out a total inspection of the input systems, output systems, and PCM to determine the cause of trouble. Otherwise, a wrong diagnosis will be made.

PCM inspection preparation

1.Disconnect the negative battery cable.

2.Remove the battery and battery tray. (See BATTERY REMOVAL/INSTALLATION [L5].)

3.Remove the windshield wiper arm and blade. (SeeWINDSHIELD WIPER ARM AND BLADE REMOVAL/INSTALLATION.)

4.Remove the cowl grille. (SeeCOWL GRILLE REMOVAL/INSTALLATION.)

5.Remove the windshield wiper motor. (SeeWINDSHIELD WASHER MOTOR REMOVAL/INSTALLATION.)

6.Remove the cowl panel. (SeeCOWL PANEL REMOVAL/INSTALLATION.)

7.Remove the PCM bracket with the PCM connector still connected. (SeePCM REMOVAL/INSTALLATION [L5].)

8.Install the battery and battery tray. (See BATTERY REMOVAL/INSTALLATION [L5].)

9.Connect the negative battery cable.

Using M-MDS

Note

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

― CMP sensor

― Main relay

1.Connect the M-MDS to the DLC-2.

acxwzw00002122

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.

• For input/output signals except those of the monitoring items, use a voltmeter to measure the PCM terminal voltage.

• The simulation items that are used in the ENGINE CONTROL SYSTEM OPERATION INSPECTION are as follows.

― ACCS, ALTF, ARPMDES, EVAPCP, FAN_DUTY, FP, IMRC, IMTV, INJ_1~4, SEGRP, TEST, VT Duty1 wt
