Hyundai Venue: Engine Control System / Engine Control Module (ECM). Repair procedures
| 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 operates normally then the problem was likely with 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, this is intermittent problem.
(Refer to Intermittent Problem Procedure in Basic Inspection Procedure)
|
| • |
When replacing the ECM, the vehicle equipped with immobilizer
must be performed the procedure as below.
|
[In the case of installing used ECM]
| 1) |
Perform "ECM neutralization mode" procedure with diagnostic
tool.
(Refer to Body Electrical System - "Immobilizer System")
|
| 2) |
Insert the key and turn it to the IGN ON and OFF position.
Then the ECM key register process is completed automatically.
|
[In the case of installing new ECM]
| – |
Insert the key and turn it to the IGN ON and OFF position.
Then the ECM key register process is completed automatically.
|
|
| 1. |
Turn ignition switch OFF and disconnect the battery negative (-) terminal.
|
| 2. |
Remove the battery.
(Refer to Engine Electrical System - "Battery")
|
| 3. |
Disconnect the ECM connector (A).
|
| 4. |
Remove the mounting bolts, and then remove the ECM bracket assembly
(B).
|
ECM Bracket installation bolt :
9.8 - 11.8 N.m (1.0 - 1.2 kgf.m, 7.2 - 8.7 lb-ft)
|
|
| 5. |
Remove the ECM (B) after loosening the mounting nuts (A) from the bracket.
|
ECM Mounting nut :
0.9 - 0.95 N.m (0.09 - 0.097 kgf.m, 0.66 - 0.7 lb-ft)
|
|
| • |
When replacing the ECM, the vehicle equipped withthe immobilizer
must be performed procedure as below.
|
[In the case of installing used ECM]
| 1) |
Perform "ECM Neutral mode" procedure with diagnostic tool.
(Refer to Body Electrical System - "Immobilizer System")
|
| 2) |
After finishing "ECM Neutral mode", perform "Keyteaching" procedure
with diagnostic tool.
(Refer to Body Electrical System - "Immobilizer System")
|
[In the case of installing new ECM]
| – |
Perform "Key teaching" procedure with diagnostic tool.
(Refer to Body Electrical System - "Immobilizer System")
|
|
| • |
When replacing the ECM, the vehicle equipped withthe smart key
system (Button start) must beperformed procedure as below.
|
[In the case of installing used ECM]
| 1) |
Perform "ECM Neutral mode" procedure with diagnostic tool.
(Refer to Body Electrical System - "Immobilizer System")
|
| 2) |
After finishing "ECM Neutral mode", insert the key(or press
the start button) and turn it to the IGN ONand OFF position.
Then the ECM learns the smartkey information automatically.
|
[In the case of installing new ECM]
| – |
Insert the key (or press the start button) and turn itto the
IGN ON and OFF position.
Then the ECM learns the smart key information automatically.
|
|
| 1. |
Installation is reverse of removal.
|
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. |
Turn the ignition switch OFF.
|
| 2. |
Connect the diagnostic tool to Data Link Connector (DLC).
|
| 3. |
Turn the igntion switch ON.
|
| 4. |
Select "Vehicle, Model Year, Engine, System".
|
| 5. |
Select "Vehicle S/W Management".
