Using 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
Scheme 126
- Connect the M-MDS to the DLC-2.
- Turn the ignition switch to the ON position.
- 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, EVAPCV, FAN_DUTY, FP, IMRC, IMTV, INJ_1~4, SEGRP, TEST, VT Duty1 wt

PID/DATA MONITOR CHART
- Following PIDs are for the ATX models. If inspects for following PIDs, (See «ON-BOARD DIAGNOSTIC SYSTEM PID/DATA MONITOR INSPECTION [FS5A-EL]»(ref-375402-S21806660812010102800000) .)
Without Using the M-MDS
| CAUTION | The PCM terminal voltages vary with change in measuring conditions and vehicle conditions. Always carry out a total inspection of the input systems, output systems, and PCM to determine the cause of trouble. Otherwise, a wrong diagnosis will be made. |
PCM CONFIGURATION [L5]
Note. Use the IDS (laptop PC) because the PDS (Pocket PC) does not support the PCM CONFIGURATION.
- Connect the M-MDS to the DLC-2.
- After the vehicle is identified, select the following items from the initial screen of the M-MDS. When using the IDS (laptop PC) Select the "Module Programming".
- Then, select items from the screen menu in the following order. Select "Programmable Module Installation". Select "PCM".
- Perform the configuration according to the directions on the screen.
- Retrieve DTCs by the M-MDS, then verify that there is no DTC present. If a DTC(s) is detected, perform the applicable DTC inspection. (See «DTC TABLE [L5]»(ref-375346-S28771957642010102800000) .)
