Repair procedures

Removal

CAUTION

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 "Immobilizer" in BE group)
2. After finishing "ECM Neutral mode", perform "Key teaching" procedure with GDS. (Refer to "Immobilizer" in BE group)

[In the case of installing new ECM]

Perform "Key teaching" procedure with GDS. (Refer to "Immobilizer" in BE group)

CAUTION

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 "Smart key" in BE group)
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.

1. Turn ignition switch OFF and disconnect the negative (-) battery cable.

2. Disconnect the ECM Connector (A).

3. Remove the battery (Refer to "Intake And Exhaust System" in EM group).

4. Remove the mounting bolts (A) and nut (B), and then remove the ECM assembly (C).

5. Remove the installation nuts (A), and then remove the ECM (B) from the bracket.

Installation

CAUTION

When replacing the ECM, the vehicle equipped with the immobilizer must be performed procedure as below.

[In the case of installing new ECM]

Insert the key (or press the start button) and turn ft to the IGN ON and OFF position. Then the ECM learns the smart key information automatically.

1. Installation is reverse of removal.

ECM installation nut: 9.8 ~ 11.8 N.m (1.0 ~ 1.2 kgf.m,7.2 ~ 8.7 lb-ft)

ECM bracket installation bolt/nut: 9.8 ~ 11.8 N.m (1.0 ~ 1.2 kgf.m,7.2 ~ 8.7 lb-ft)

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, 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).
