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.
Specification : below 1Ω
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)
Removal
1.
Turn ignition switch OFF and disconnect the negative (-) battery terminal.
2.
Remove the battery. (Refer to Engine Electrical System - "Battery")
3.
Disconnect the ECM Connector (A).
4.
Remove the mounting bolts (B) and nut (C), and then remove the ECM bracket assembly.
5.
Remove the mounting screws and then remove the ECM from the bracket.
installation
1.
Install in the reverse order of removal.
ECM mounting nut :
9.8 ~ 11.8 N.m (1.0 ~ 1.2 kgf.m, 7.2 ~ 8.7 lb-ft)
ECM bracket mounting bolt/nut :
9.8 ~ 11.8 N.m (1.0 ~ 1.2 kgf.m, 7.2 ~ 8.7 lb-ft)
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.
