Step A - Confirm If the Vehicle Requires ECM Reprogramming

Step A: Confirm if the vehicle requires ECM Reprogramming

Check the Current ECM Part Number (P/N)

1. With CONSULT-II, print the ECM Part Number as follows:

[START(Nissan)] >> [ENGINE] >> [ECM PART NUMBER] >> [COPY]

2. Attach this printout to the Repair Order.





^ Figure 1 is an example of the ECM Part Number printout.

^ You will use the ECM Part Number (P/N) to see if your vehicle needs ECM reprogramming.

Compare Your Current ECM P/N To Chart A

3. Using the ECM P/N printout from Step 2 (Figure 1):





^ Compare your vehicle's ECM P/N to those shown under Current ECM P/N in Chart A, above.

A. If your vehicle's ECM P/N matches one of the Current ECM P/N's in the chart above:

^ Reprogramming is needed. Continue with Step B, Reprogram the ECM.

B. If your vehicle's ECM P/N does not match one of the Current ECM P/N's in the chart above:

^ Reprogramming is NOT needed. Continue with Step C.
