Function Inspection

  1. Connect the M-MDS to the DLC-2.
  2. Switch the ignition ON (engine off).
  3. Display the PIDs MAP_V and MAP. (See ON-BOARD DIAGNOSTIC TEST [PCM (VIN L (WITHOUT CYLINDER DEACTIVATION))] .) (See PCM INSPECTION [VIN L (WITHOUT CYLINDER DEACTIVATION)] .)
  4. Compare the voltage and manifold absolute pressure indications for the PIDs MAP_V and MAP with the standard in the table indicated below.
    • If they do not match the standard, perform the voltage inspection. (See Voltage Inspection .)
