Kia Sportage QL (2015-2019) Service Manual / Engine Control / Fuel System / Engine Control System / Engine Control Module (ECM) Repair procedures

Removal
1.
Turn ignition switch OFF and disconnect the battery negative (-) terminal.
2.
Remove the air cleaner and intake hose.
(Refer to Engine Mechanical System - "Air Cleaner")
3.
Remove the battery and battery tray.
(Refer to "Engine Electrical System" - Battery")
4.
Disconnect the ECM Connector (A).
5.
Remove ECM bracket assembly (B) after loosening the mounting bolts and nut.
ECM bracket mounting nut :
9.8 - 14.7 N·m (1.0 - 1.5 kgf·m, 7.2 - 10.8 lb·ft)
ECM bracket mounting bolt :
21.5 - 32.3 N·m (2.2 - 3.3 kgf·m, 15.9 - 23.8 lb·ft)

6.
Remove the ECM after loosening the mounting nuts (A).
ECM mounting nut:
8.8 - 11.8 N·m (0.9 - 1.2 kgf·m, 6.5 - 8.7 lb·ft)

Installation
1.
Install in the reverse order of removal.
ECM Problem Inspection Procedure
1.
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 1Ω
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.
4.
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
ECM Neutral Mode procedure (With Immobilizer)
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 KDS/GDS.
(Refer to "Body Electrical System - "Immobilizer System - Repair procedures")
2)
After finishing "ECM Neutral Mode", perform "Key Teaching" procedure using KDS/GDS.
(Refer to "Body Electrical System - "Immobilizer System - Repair procedures")
[If installing a new ECM]
Perform "Key Teaching" procedure using KDS/GDS.
(Refer to "Body Electrical System - "Immobilizer System - Repair procedures")
ECM Neutral Mode procedure (With Smart key)
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 KDS/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.
(Refer to "Body Electrical System - "Smart key System - Repair procedures")
[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.
(Refer to "Body Electrical System - "Smart key System - Repair procedures")
ETC module learning procedure
Perform ETC module learning after replacing the ETC module.
(Refer to Electronic Throttle Control System - "Adjustment")
TCM learning procedure
Perform TCM learning after replacing the PCM.
(Refer to Automatic Transaxle Control System - "Adjustment")
VIN programming procedure
VIN (Vehicle Identification Number) is a number that has the vehicle's information (Maker, Vehicle Type, Vehicle Line/Series, Body Type, Engine Type, Transmission Type, Model Year, Plant Location and so forth. For more information, please refer to the group "GI" in this SERVICE MANUAL). When replacing an ECM, the VIN must be programmed in the ECM. If there is no VIN in ECM memory, the fault code (DTC P0630) is set.
  
The programmed VIN cannot be changed. When writing the VIN, confirm the VIN carefully.
1.
Select "VIN Writing" function in "Vehicle S/W Management".
2.
Select "Write VIN" in "ID Resister".

3.
Input the VIN.
  
Before inputing the VIN, confirm the VIN again because the programmed VIN cannot be changed.
