NOTE: Record all programmable parameters, features, and calibration data from the old ECM before disconnecting the harness connectors. This data will be needed to program the new ECM.

Disconnect the 36-pin engine harness (1), 89-pin OEM harness (2), and the 16-pin engine harness (3) connectors from the ECM.

 CAUTION 

Do not paint the cooling plate. Make sure there is no grease or dirt between the ECM and the cooling plate. Otherwise, debris can get into the fuel system.

Install the ECM onto the cooling plate.

Tighten the three capscrews

only enough to secure the ECM to the cooling plate.

Tighten the capscrews to the proper torque in the sequence shown in the art.

Torque Value:  10  n.m  [89 in-lb]

Mount the ECM/cooling plate assembly to the engine.

Torque Value:  24  n.m  [212 in-lb]

Install the vibration and grounding grommets, and the ECM ground strap.

 CAUTION 

To reduce the possibility of ECM damage, do not blow compressed air into the ECM ports or connectors. Compressed air can contain moisture due to condensation.

Use quick-dry electrical contact cleaner, Part Number 3824510, to remove all dirt and moisture from the ECM connector ports and harness connectors.

Connect the OEM and engine harness connectors to the ECM. The engine harness connectors and the OEM harness connector have an arm on the connector that will snap down on itself when properly connected to the ECM.

NOTE: When an ECM is replaced, the new ECM

must be calibrated. Refer to Procedure 019-032.
