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 KDS/GDS.
(Refer to "Body Electrical System - "Immobilizer System - Repair procedures")
|
2) |
After finishing "ECM Neutral Mode", perform "Key Teaching" procedure
using KDS/GDS.
(Refer to "Body Electrical System - "Immobilizer System - Repair procedures")
|
[If installing a new ECM]
Perform "Key Teaching" procedure using KDS/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 KDS/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.
(Refer to "Body Electrical System - "Smart key System - Repair procedures")
|
[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 System - Repair procedures")
