PCM INSPECTION [L3]

BME014018880W02

  Note

  • PIDs for the following parts are not available on this model. Go to the appropriate part inspection page.

  - CMP sensor (See CAMSHAFT POSITION (CMP) SENSOR INSPECTION [L3].)
  - Main relay (See 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
  - ARPMDES
  - EVAPCP
  - FAN DUTY
  - FP
  - FUELPW1
  - GENVDSD
  - HTR11
  - HTR12
  - IAC
  - IMRC
  - IMTV
  - INJ_1, INJ_2, INJ_3, INJ_4
  - SEGRP
