PCM INSPECTION
A6E394018880W02
Using SST (WDS or Equivakent)
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.
— ACCS
— ALTF
— EVAPCP
— FAN1
— FAN2
— FAN3
— FP
— HTR11
— HTR12
— IAC
— IASV
— IMRC
— IMTV
— VT DUTY1
