Diagnostic Procedure

Step

Inspection

Results

Action

1

RECORD VEHICLE STATUS WHEN DTC WAS DETECTED TO UTILIZE WITH REPEATABILITY VERIFICATION

Note

•  Recording can be facilitated using the screen capture function of the PC.

•  Record the freeze frame data/snap shot data.

—

Go to the next step.

2

VERIFY OTHER RELATED DTCs

•  Switch the ignition OFF, and then switch it ON (engine off).

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

•  Has any DTC other than P167B:00 been stored?

Yes

Repair the malfunctioning location according to the applicable DTC troubleshooting.

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

No

Go to the next step.

3

PERFORM FUEL INJECTION LEARNING

•  Perform the fuel injection learning.
(See FUEL INJECTOR INJECTION AMOUNT CORRECTION [SKYACTIV-D 2.2].)

•  Start the engine.

•  Verify the warning/indicator light condition.

•  Do the warning/indicator lights turn off?

Yes

Go to the next step.

No

Verify that the implementation conditions for fuel injection amount learning are met, and perform the PCM fuel injection amount learning again.

(See FUEL INJECTOR INJECTION AMOUNT CORRECTION [SKYACTIV-D 2.2].)

Go to the next step.

4

VERIFY DTCs

•  Reconnect all disconnected connectors and hoses.

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

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

•  Is DTC P167B:00 displayed?

Yes

Repeat the inspection from Step 1.

•  If a malfunction occurs, change the learning method (use/do not use M-MDS), and perform the fuel injection amount learning again.
(See FUEL INJECTOR INJECTION AMOUNT CORRECTION [SKYACTIV-D 2.2].)

Go to the next step.

No

Go to Step 6.

5

VERIFY THAT REPAIRS HAVE BEEN COMPLETED

•  Reconnect all disconnected connectors and hoses.

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

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

•  Has DTC P167B:00 been recorded?

Yes

Repeat the inspection from Step 1.

•  If the malfunction recurs, replace the PCM, then go to the next step.
(See PCM REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)

No

Go to the next step.

6

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.
