| Removal |
When replacing the ECM, the vehicle equipped with the immobilizer must
be performed procedure as below.
[In the case of installing used ECM]
1) Perform "ECM Neutral mode" procedure with GDS.
(Refer to Body Electrical System - "Immobilizer System")
2) After finishing "ECM Neutral mode", perform "Key teaching" procedure
with GDS.
(Refer to Body Electrical System - "Immobilizer System")
[In the case of installing new ECM]
Perform "Key teaching" procedure with GDS.
(Refer to Body Electrical System - "Immobilizer System")

When replacing the ECM, the vehicle equipped with the smart key system
(Button start) must be performed procedure as below.
[In the case of installing used ECM]
1) Perform "ECM Neutral mode" procedure with GDS.
(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 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.

| 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, 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).
