PCM INSPECTION [FS]

A3U014018880W02

Caution

••••

The PCM terminal voltages vary with change in measuring conditions and vehicle conditions.
Always complete the inspection of the input systems, output systems, and PCM to determine the
cause of trouble. Otherwise, diagnosis will fail.

PCM Inspection Using the SST (WDS or equivalent)

Note

•

PIDs for the following parts are not available on this model. Go to the appropriate part inspection page.
— CMP sensor (See 01–40B–35 CAMSHAFT POSITION (CMP) SENSOR INSPECTION [FS].)
— Main relay (See 09–21–5 RELAY INSPECTION.)

1. Connect the WDS or euivalent to the DLC-2. (See 01–02B–7 ON-BOARD DIAGNOSTIC TEST [FS].)
2. Turn the ignition switch on.
3. Measure the value.

•

If the value is not within the specification, follow the instruction in Action column.
