PCM INSPECTION

id014000802500

Not Using the WDS or Equivalent

Note

• The PCM terminal voltage can vary with conditions when measuring and changes due to age deterioration on the vehicle, causing false diagnosis. Therefore a comprehensive inspection of the input and output systems, and the PCM is necessary to determine where the malfunction occurs.

Using the WDS or Equivalent

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 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, AIP RLY, ALTF, APV, ARPMDES, DEI, ETC_DSD, EVAPCP, FAN1, FAN2, FP, FPRR, FUELPW, GENVDSD, HTR11, HTR12, IASV, MOP POS, PACNTV, SSV, test
