A. On your C-III screen look at the Part Number column (see Figure 1):

^ If this column is blank (no part number listed) this bulletin does not apply. Close C-III and refer to ASIST for further diagnostic information.

^ If a Part Number is listed write it on the Repair Order.





B. Compare the Part Number you wrote down to the numbers in the Current ECM Part Number column in Table A.

^ If there is not a match, this bulletin does not apply. Close C-III and refer to ASIST for further diagnostic information.





3. If this bulletin applies and you have performed ECM reprogramming, the screen in Figure 2 appears when reprogramming is complete.

4. Make sure to erase DTCs from all Systems.

NOTE:
During reprogramming DTCs will set in several systems and must be erased.
