Mazda 6 Service Manual: Pcm inspection

Mazda 6 Service Manual / Fuel and emission control systems / Control system / Pcm inspection

Note

PIDs for the following parts are not available on this model. Go to the appropriate part inspection page.

- CMP sensor (See CAMSHAFT POSITION (CMP) SENSOR INSPECTION.)

- Main relay (See RELAY INSPECTION.)

1. Connect the SST

(WDS or equivalent) to the DLC-2.

2. Turn the ignition switch to 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.
For input/output signals except those of the monitoring items, use a voltmeter to measure the PCM terminal voltage.
The simulation items that are used in the ENGINE CONTROL SYSTEM OPERATION INSPECTION are as follows.

- ACCS

- ALTF

- EVAPCP

- FAN1

- FAN2

- FAN3

- FP

- HTR11

- HTR12

- IAC

- IASV

- IMRC

- IMTV

- VT DUTY1

PID/DATA monitor table (reference)

*1 : Calculated value; differs from terminal voltage

*2 : Refrigerant pressure switch (middle) turns on when the refrigerant pressure is 1.691.84 MPa {17.318.7 kgf/cm2, 247265 psi}

*3 : Refrigerant pressure switch (middle) turns off when the refrigerant pressure is 1.261.49 MPa {12.915.1 kgf/cm2, 184214 psi}

*4 : L3 and L8, LF (Intensely hot area) models

*5 : Immobilizer system equipped
