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.

Scheme 57: Using The M-MDS
  1. Connect the M-MDS to the DLC-2. (Scheme 57): Identifying 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.

PCM CONFIGURATION [MZR 1.5]

  1. Connect the M-MDS (IDS) to the DLC-2.
  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 "Module Programming". Select "Programmable Module Installation". Select "PCM".
  3. Perform the configuration according to the directions on the screen.
  4. 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 [MZR 1.5]»(ref-517437-S01450735222012121200000) .)

Scheme 58

Scheme 58: NEUTRAL SWITCH INSPECTION [MZR 1.5]
  1. Disconnect the negative battery cable.
  2. Remove the neutral switch. (See «NEUTRAL SWITCH REMOVAL/INSTALLATION [F35M-R]»(ref-517458-S03452429082012121200000).)
  3. Inspect for continuity between the neutral switch terminals using an ohmmeter. (Scheme 58): Identifying Neutral Switch Connector Terminals If not as specified, replace the neutral switch. (See «NEUTRAL SWITCH REMOVAL/INSTALLATION [F35M-R]»(ref-517458-S03452429082012121200000).)
