PCM INSPECTION [13B-MSP]

id0140g1802500


Without Using the SST

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 the M-MDS

Note
•  PIDs for the following parts are not available on this model. Go to the appropriate part inspection page.
―  Main relay (See RELAY INSPECTION.)

1.  Connect the M-MDS to the DLC-2.

ar8uuw00001795

2.  Turn the ignition switch 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 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.
Caution
•  To prevent engine damage, use MOP_FL_C and MOP_FL_S only during idling (after engine warm-up) up to 30 s.
