PCM INSPECTION [MZR-CD (RF Turbo)]

BME014018880W04

## Using WDS or Equivalent

  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, diagnosis will be incorrect.

  Note

  • Perform "Correction after Parts Installation" after replacing the PCM. (See Correction after Parts Installation.)

1. Connect the WDS or equivalent to the DLC-2. (See ON-BOARD DIAGNOSTIC TEST [MZR-CD (RF Turbo)].)

2. Turn the engine switch to ON.

3. Measure the PID value.

  • If PID value is not within the specification, follow the instructions in ACTION column.

  (1) Measurement voltage is below 1.0 V.

  1) Turn the engine switch to OFF.
  2) Disconnect the accelerator position sensor connector.
  3) Verify there is no continuity between the accelerator position sensor terminal A (vehicle side) and body GND using an ohmmeter.
