Repair procedures
Removal
1.
Switch "OFF" the ignition and disconnect the negative (-) battery terminal.
2.
Remove the air cleaner assembly.
(Refer to Engine Mechanical System - "Air Cleaner")
3.
Remove the battery tray.
(Refer to Engine Electrical System - "Battery")
4.
Disconnect the ECM Connector (A).
5.
Remove the ECM bracket assembly (B) after loosening the mounting bolt and nuts,
ECM Bracket mounting bolt / nut :
9.8 - 11.8 N.m (1.0 - 1.2 kgf.m,7.2 - 8.7 lb-ft)

Hyundai Palisade. Repair procedures

6.
Remove the ECM after loosening the mounting nuts (A) and screw (B).
ECM Mounting bolt / nut :
9.8 - 11.8 N.m (1.0 - 1.2 kgf.m,7.2 - 8.7 lb-ft)

Hyundai Palisade. Repair procedures

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 steps 1 and 2, the ECM could be faulty. In this case, make sure that there are no DTC's before replacing the ECM with a new one, and then check the vehicle again. If DTC's are found, examine them first before replacing the ECM.
4.
RE-TEST THE ORIGINAL ECM : Install the original ECM (possibly broken) into a known-good vehicle and check the vehicle. If the problem reoccurs, replace the original ECM with a new one. If problem does not reoccur, this is an 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 diagnostic tool.
(Refer to Body Electrical System - "Immobilizer System")
2)
After finishing "ECM Neutral Mode", perform "Key Teaching" procedure using diagnostic tool.
(Refer to Body Electrical System - "Immobilizer System")
[If installing a new ECM]
Perform "Key Teaching" procedure using diagnostic tool.
(Refer to Body Electrical System - "Immobilizer System")
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 diagnostic tool.
(Refer to Body Electrical System - "Smart Key")
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")
[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")
ETC module learning procedure
Perform ETC module learning after replacing the ETC module.
(Refer to Electronic Throttle Control System - "Adjustment")
VIN programming procedure
VIN (Vehicle Identification Number) is a number with the vehicle 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) will be set.
Hyundai Palisade. Repair procedures   
VIN cannot be changed once it is programmed. Confirm carefully when writing the VIN.
1.
Select "VIN Writing" function in "Vehicle S/W Management".
2.
Select "Write VIN" in "ID Register" menu.

Hyundai Palisade. Repair procedures

3.
Enter the VIN.
Hyundai Palisade. Repair procedures   
Before entering the VIN, confirm again as it cannot be changed once programmed.
