PCM INSPECTION
A6E394018880W02
Note
• PIDs for the following parts are not available on this model. Go to the appropriate part inspection page.
 CMP sensor (See F55 CAMSHAFT POSITION (CMP) SENSOR INSPECTION.)
 Main relay (See T24 RELAY INSPECTION.)
1. Connect the SST (WDS or equivalent) to the
DLC-2.
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.
