PCM INSPECTION [MZR 2.0 DISI]

id0140j3802500


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.

1.  Measure the voltage at each terminal.

•  If any incorrect voltage is detected, inspect the related system(s), wiring harnesses and connector(s) referring to the Action column in the terminal voltage table.

Using M-MDS

1.  Connect the M-MDS to the DLC-2.

am3uuw00002382

2.  Switch the ignition to ON.

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, FAN1, FAN2, FAN3, FP, IMRC, IMTV, INJ_1~4, SEGRP, Test, VT Duty1 wt
