Scheme 33

Scheme 33: Using M-MDS
  1. Connect the M-MDS to the DLC-2. (Scheme 33): Identifying DLC-2
  2. Switch the ignition to ON.
  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, EVAPCV, FAN_DUTY, FP, HTR11, IMRC, IMTV, INJ_1~4, SEGRP, Test, VT Duty1 wt

CAUTIONThe 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.
  1. Measure the voltage at each terminal. If any incorrect voltage is detected, inspect the related system(s), wiring harnesses and connector(s) referring to the Action column in the terminal voltage table.

PCM CONFIGURATION [MZR 2.5]

Note. When performing the PCM configuration and PCM reprogramming simultaneously, perform the PCM configuration and then perform the PCM reprogramming after the session has been completed. If the PCM reprogramming is performed with the session not completed, it may result in improper operation of the PCM.

Scheme 46

Scheme 46: PCM CONFIGURATION [MZR 2.5]
  1. Connect the M-MDS (IDS) to DLC-2. (Scheme 46): Identifying DLC-2
  2. After the vehicle is identified, select the following items from the initial screen of the M-MDS (IDS). Select "Module Programming".
  3. Then, select items from the screen menu in the following order. Select "Programmable Module Installation". Select "PCM".
  4. Perform the configuration according to the directions on the screen.
  5. Retrieve DTCs by the M-MDS (IDS), then verify that there is no DTC present. (See «ON-BOARD DIAGNOSTIC TEST [MZR 2.5]»(ref-581633-S34331335932013101400000).) If a DTC (s) is detected, perform the applicable DTC inspection. (See «DTC TABLE [MZR 2.5]»(ref-581633-S19834179122013101400000).)

Scheme 47

Scheme 47: CLUTCH PEDAL POSITION (CPP) SWITCH INSPECTION [MZR 2.5]
  1. Verify that the CPP switch is installed properly.
  2. Disconnect the negative battery cable. (See «BATTERY REMOVAL/INSTALLATION [MZR 2.5]»(ref-581638-S19258420632013101400000).)
  3. Disconnect CPP switch connector. (See «CLUTCH PEDAL REMOVAL/INSTALLATION [G66M-R]»(ref-581653-S14638623202013101400000).)
  4. Inspect for continuity between CPP switch terminals A and B. (Scheme 47): Identifying CPP Switch Connector Terminals If not as specified, replace the CPP switch. (See «CLUTCH PEDAL REMOVAL/INSTALLATION [G66M-R]»(ref-581653-S14638623202013101400000).)
