PCM INSPECTION [MZR-CD (RF Turbo)]


BME014018880204

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.
