PCM REMOVAL/INSTALLATION [SKYACTIV-G 1.5, SKYACTIV-G 2.0]

id0140g8802400

Caution

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

• When performing configuration and reprogramming, 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.

Without Set Bolt

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

2. Set the resonance duct and air intake hoses No.1 and 2 aside as a single unit using the following procedure. (With resonance chamber No.2)

(1) Remove the bolt shown in the figure.

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 1.5, SKYACTIV-G 2.0].)

(1) Perform the PCM configuration. (See PCM CONFIGURATION (USING READ/WRITE FUNCTION) [SKYACTIV-G 1.5, SKYACTIV-G 2.0].)

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

(3) Switch the ignition off, and disconnect the negative battery cable. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION.) (with i-stop system)

(4) Perform the Battery Condition Initialization Setting (i-stop setting) Procedure. (See BATTERY CONDITION INITIALIZATION SETTING (i-stop SETTING).) (with i-stop system)

2. Temporarily tighten the two set bolts, then completely tighten them.

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.
