PCM INSPECTION [ZJ, Z6]


B3E014018880W08

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.
- CMP sensor (See CAMSHAFT POSITION (CMP) SENSOR INSPECTION [ZJ, Z6].)
- Main relay (See RELAY INSPECTION.)

1. Connect the WDS or equivalent to the DLC-2.

2. Turn the ignition switch to the 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.
• 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, test, VT ACT1, VT DUTY1
