PCM REMOVAL/INSTALLATION [SKYACTIV-G 2.5]

id0140g0802400

Caution

•  There are two types of PCM settings. If the incorrect PCM is installed, it could cause interference with engine control.

•  When replacing the PCM, verify the first four digits of the part number indicated on the PCM label before replacement, and replace the PCM with one having the same part number.

•  If configuration is not performed when the PCM is replaced with a new one, the vehicle specification information is not stored in the PCM and the system will not operate normally.

•  When performing configuration, it is necessary to read the vehicle specification information from the PCM before replacing it. Connect the M-MDS to the vehicle and perform vehicle identification before removing the PCM. The vehicle specification information is temporarily stored in the M-MDS.

Note

•  The PCM prior to replacement stores the vehicle specification information.

•  A new PCM does not store any vehicle specification information.

•  If the vehicle specification information PCM prior to replacement cannot be read, perform the configuration using As-Built data.

1.  Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION.)

2.  Remove the PCM cover. (See PCM Cover Installation Note.)

6.  Install in the reverse order of removal.

7.  When replacing the PCM on the vehicles, perform the following:

Note

•  If configuration cannot be performed by reading/writing of the vehicle specification information, perform the configuration using As-Built information after replacing the PCM. (See PCM CONFIGURATION (USING AS-BUILT DATA) [SKYACTIV-G 2.5].)

(1)  Perform the PCM configuration. (See PCM CONFIGURATION (USING READ/WRITE FUNCTION) [SKYACTIV-G 2.5].)

(2)  Perform the immobilizer system-related part programming. (See IMMOBILIZER SYSTEM-RELATED PARTS PROGRAMMING.)

(3)  Switch the ignition off, and disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION.)

(4)  Perform the battery condition initialization setting (i-stop setting) procedure. (See BATTERY CONDITION INITIALIZATION SETTING (i-stop SETTING).)

PCM Connector Connection Note

Caution

•  Do not touch the PCM connector terminal. The terminal is extremely thin and can be damaged by touching it.

•  If the PCM connector is inserted at an angle and the lever is moved, the connector could be damaged. Verify that the PCM connector is inserted straight.
