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.
|
1) |
[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")
|
2) |
[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.
|
1) |
[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.
|
2) |
[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.
|
• |
Perform TCM learning after replacing the PCM. (Refer to Automatic
Transaxle Control System - "Adjustment")
