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 P16AB: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.

2

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.
