id0102j5159300

Note

• To determine the malfunctioning part, proceed with the diagnostics from [Function inspection using M-MDS].

Details on DTCs

System malfunction location

BARO sensor in PCM: Run error

Detection condition

Determination condition

•  Malfunction in BARO sensor signal circuit in PCM occurs.

Preconditions

•  All of the following conditions are met.

―  Battery voltage: 8—16 V

―  0.5 s elapses after engine is started

Drive cycle

•  1

Self-test type

•  CMDTC self test

Sensor/unit used

•  BARO sensor (integrated with PCM)

Fail-safe

•  Limits engine torque.

•  Limits the maximum engine speed.

•  Inhibits the automatic diesel particulate filter regeneration control.

•  Inhibits the manual diesel particulate filter regeneration control.

•  Inhibits the EGR control.

•  Stops the G-vectoring control (GVC).

•  Limits the engine transaxle total control.

•  Inhibits engine-stop by i-stop control.

Vehicle status when DTCs are output

•  Check engine light turns on

Possible Cause

•  BARO sensor malfunction (integrated with PCM)

•  PCM malfunction

System Wiring Diagram

• Not applicable

Function Explanation (DTC Detection Outline)

• If there is communication error between the BARO sensor control driver and the CPU, the PCM stores a DTC.

Repeatability Verification Procedure

• Leave the vehicle for 10 s with the ignition switched ON (engine off) or while idling.

PID Item/Simulation Item Used in Diagnosis

• Not applicable

Troubleshooting Diagnostic Procedure

Intention of troubleshooting procedure

• Step 1

― Perform a unit inspection of the BARO sensor.

• Steps 2 to 3

― Verify that the primary malfunction is resolved and there are no other malfunctions.

Inspection

Results

Action

1

PURPOSE: INSPECT BARO PRESSURE SENSOR

•  Inspect the BARO sensor.
(See BAROMETRIC PRESSURE (BARO) SENSOR INSPECTION [SKYACTIV-D 2.2].)

•  Is the BARO sensor normal?

Yes

Go to the next step.

No

Replace the PCM, then go to the next step.

(See PCM REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)

2

VERIFY THAT REPAIRS HAVE BEEN COMPLETED

•  Reconnect all the disconnected connectors.

•  Refer to the [MEMORY CLEARING PROCEDURE] and clear the DTC.
(See CLEARING DTC [PCM (SKYACTIV-D 2.2)].)

•  Implement the repeatability verification procedure.
(See Repeatability Verification Procedure.)

•  Display the DTCs using the M-MDS.
(See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-D 2.2)].)

•  Has DTC P2226:00 been recorded?

Yes

Replace the PCM, then go to the next step.

(See PCM REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)

No

Go to the next step.

3

VERIFY OTHER DTCs

•  Has any other DTC or pending code been stored?

Yes

Repair the malfunctioning location according to the applicable DTC troubleshooting.

(See DTC TABLE [PCM (SKYACTIV-D 2.2)].)

No

DTC troubleshooting completed.
