Repair the ECM Connection (All Incident Cases)

1. Remove the left- and right-hand side trim panels from either side of the center console to access the ECM (see Figure 2).





2. Unlatch the ECM Connector by depressing the left tab (see Figure 3).





3. Rotate the black latch that holds the ECM Connector in place from left to right. Completely engage the latch at the right tab. See Figure 4.





4. Disconnect the ECM Connector (see Figure 5 and Figure 6).

CAUTION:
When completing step 5 DO NOT allow the ECM Harness to make contact with the metal bracket directly above the harness (see Figure 5).





5. Relieve tension in the ECM Harness bend by pulling the ECM Connector and Harness backward and forward (see Figure 6).

6. Now re-connect the ECM Connector.





^ Align the ECM Connector with the ECM (see Figure 7).

^ Apply equal hand pressure to the left and right side of the ECM Connector to reconnect it (see Figure 7).





7. Unsnap the black latch from the right tab. Latch the ECM Connector securely in place by rotating the black latch backward and completely engaging it into the left tab (see Figure 8). It should snap in place.

8. Reinforce the ECM connection by wrapping two 18 inch or longer nylon/plastic tie wraps completely around the ECM and connector, as described in the steps provided below.

NOTE:
Use one 18 inch or longer nylon/plastic tie wrap each for front and back reinforcement of the ECM in this procedure. DO NOT mate two smaller tie wraps together. This may not keep reliable force on the connector and DTC codes may be repeated.





A. Feed the two nylon/plastic tie wraps under the wire harness and over the top of the ECM (see Figure 9).

CAUTION:
Avoid passing the tie wraps over any brackets that protrude from the top of the ECM.





B. Wrap the tie wraps from the top around to the bottom of the ECM. Feed the tie wraps back through to the passenger side (See Figure 10).





C. Mate up and latch the two tie wraps (see Figure 11).





D. Align the front tie wrap into the V-shaped arch on the right (front) side of the ECM Connector (see Figure 12A).

E. Align the back tie wrap with the solid, flat surface of the left (back) side of the ECM Connector (see Figure 12A).

F. Hand tighten both tie wraps (see Figure 12A).

CAUTION:
DO NOT apply too much force when tightening both tie wraps. This may result in damage to the outer protective plastic shield of the ECM Connector.

G. Push the front tie wrap in the V-shaped arch on the right (front) side of the ECM Connector (see Figure 12B).





H. Complete a final secure/tighten of the tie wraps in place. When tie wraps are properly secured and in place, cut off the excess ends of each tie wrap. See Figure 13.

9. Re-install the left- and right-hand side trim panels to the center console.

10. Look at the CONSULT-II Self-Diagnosis printout from step 2:

^ If DTC Code P0134 only or P0154 only are present, proceed to and perform Replacing Front Oxygen Sensor.

^ If any other combination of P0134, P0135, P0154, or P0155 is present, proceed to and perform Final System Check.
