Hyundai Genesis (DH): Engine Control System / Engine Control Module (ECM) Repair procedures
| Removal |
For the vehicle equipped with the immobilizer, the procedures shown below must be performed after replacing the ECM.
[In the case of installing used ECM]
1) Perform "ECM Neutral mode" procedure with GDS. (Refer to "Immobilizer" in BE group)
2) After finishing "ECM Neutral mode", perform "Key teaching" procedure with GDS. (Refer to "Immobilizer" in BE group)
[In the case of installing new ECM]
Perform "Key teaching" procedure with GDS. (Refer to "Immobilizer" in BE group)
|
For the vehicle equipped with the smart key system (Button
start), the procedures shown below must be performed after replacing the
ECM.
[In the case of installing used ECM]
1) Perform "ECM Neutral mode" procedure with GDS. (Refer to "Smart key" in BE group)
2) After finishing "ECM Neutral mode", insert the key (or
press the start button) and turn it to the IGN ON and OFF position. Then
the ECM learns the smart key information automatically.
[In the case of installing new ECM]
Insert the key (or press the start button) and turn it to the
IGN ON and OFF position. Then the ECM learns the smart key information
automatically.

| 1. |
Turn ignition switch OFF and disconnect the negative (-) battery cable. |
| 2. |
Remove the cover. |
| 3. |
Disconnect the ECM connector (A) and the IDB connector (B). |
| 4. |
Disconnect the TCM connector (C).
|
| 5. |
Remove the ECM & TCM & IDB bracket installation bolts (A) and nut (B).
|
| 6. |
Disconnect the TCM (B) from the bracket after loosening mounting bolt (A).
|
| 7. |
Disconnect the ECM (B) from the bracket after loosening mounting nut (A).
|
| Installation |
In the case of the vehicle equipped with immobilizer, perform
"Key Teaching" procedure together (Refer to "Immobilizer" in BE group). |
| 1. |
To install, reverse the removal procedure.

| 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.
|
| 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, replace the ECM with a new one, and then check the
vehicle again. If the vehicle normally operates, the problem could be
found in the 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, it is an intermittent problem (Refer to |
