Installation is reverse 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.
|
| 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 |
| • |
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 GDS. (Refer to "Body Electrical System - "Immobilizer System - Repair procedures") |
| 2) |
After finishing "ECM Neutral Mode", perform "Key Teaching"
procedure using GDS. (Refer to "Body Electrical System - "Immobilizer
System - Repair procedures") |
|
[If installing a new ECM]
Perform "Key Teaching" procedure using GDS. (Refer to "Body Electrical System - "Immobilizer System - Repair procedures") |
| • |
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 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. |
|
[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. |
| • |
After replacing ETC module or ECM, the ETC adaptive value must be reset / relearned.
(Refer to "Engine Control System - ETC - adjustment") |
