Kia Sportage: Engine Control Module (ECM): Repair procedures

Third generation SL (2010–2016) / Kia Sportage SL Service & Repair Manual / Engine Control / Fuel System / Engine Control System / Engine Control Module (ECM): Repair procedures

Removal

1.	Turn ignition switch OFF and disconnect the negative (-) battery cable.

2.	Disconnect the ECM Connector (A).

3.	Remove the battery (Refer to "Intake And Exhaust System" in EM group).

4.	Remove the mounting bolts (A) and nut (B), and then remove the ECM assembly (C).

5.	Remove the installation nuts (A), and then remove the ECM (B) from the bracket.

Installation

Installation is reverse of removal.

ECM installation nut:

9.8 ~ 11.8 N.m (1.0 ~ 1.2 kgf.m,7.2 ~ 8.7 lb-ft)

ECM bracket installation bolt/nut:

9.8 ~ 11.8 N.m (1.0 ~ 1.2 kgf.m,7.2 ~ 8.7 lb-ft)

ECM Problem Inspection Procedure

TEST ECM GROUND CIRCUIT: Measure resistance between ECM and chassis ground using the backside of ECM harness connector as ECM side check point. If the problem is found, repair it.

Specification: Below 1?

2.	TEST ECM CONNECTOR: Disconnect the ECM connector and visually check the ground terminals on ECM side and harness side for bent pins or poor contact pressure. If the problem is found, repair it.

3.	If problem is not found in Step 1 and 2, the ECM could be faulty. If so, make sure there were no DTC''s before swapping the ECM with a new one, and then check the vehicle again. If DTC''s were found, examine this first before swapping ECM.

RE-TEST THE ORIGINAL ECM: Install the original ECM (may be broken) into a known-good vehicle and check the vehicle. If the problem occurs again, replace the original ECM with a new one. If problem does not occur, this is intermittent problem (Refer to “Intermittent Problem Inspection Procedure” in Basic Inspection Procedure).

Adjustment

•	After replacing the ECM of the vehicle with the immobilizer, the following procedure must be performed.

[If installing a used ECM]

1)	Perform "ECM Neutral Mode" procedure using GDS. (Refer to "Body Electrical System - "Immobilizer System - Repair procedures")

2)	After finishing "ECM Neutral Mode", perform "Key Teaching" procedure using GDS. (Refer to "Body Electrical System - "Immobilizer System - Repair procedures")

[If installing a new ECM]

Perform "Key Teaching" procedure using GDS. (Refer to "Body Electrical System - "Immobilizer System - Repair procedures")

•	After replacing the ECM of the vehicle with the smart key system (button start), the following procedure must be performed.

[If installing a used ECM]

1)	Perform "ECM Neutral Mode" procedure using GDS. (Refer to "Body Electrical System - "Smart key System - Repair procedures")

2)	After finishing "ECM Neutral Mode", turn IGN ON then OFF using the smart key or start button. Then the ECM learns information on the smart key automatically.

[If installing a new ECM]

Turn IGN ON then OFF using the smart key or start button. Then the ECM learns information on the smart key automatically.

•	After replacing ETC module or ECM, the ETC adaptive value must be reset / relearned. (Refer to "Engine Control System - ETC - adjustment")
