PCM INSPECTION [L8, LF]


id0140i7802500

Not Using the M-MDS

Note
• The PCM terminal voltage can vary with the conditions when measuring and changes due to aged deterioration on the vehicle, causing false diagnosis. Therefore determine comprehensively where the malfunction occurs among the input systems, output systems, and the PCM.

Using the M-MDS

Note
• PIDs for the following parts are not available on this model. Go to the appropriate part inspection page.
- CMP sensor
- Main relay

1. Connect the SST (M-MDS) 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 "Inspection item (s)" 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, FUELPW1, GENVDSD, HTR11, HTR12, IMRC, IMTV, INJ_1, INJ_2, INJ_3, INJ_4, SEGRP, test, VT DUTY1 Wt
