Diagnostic Steps

1

Step 1: Check service records to identify recent injector or ECM replacements

2

Step 2: Verify all injector part numbers match vehicle specifications

3

Step 3: Attempt complete injector coding/programming procedure for all cylinders using factory scan tool

4

Step 4: If programming fails, check for ECM software updates and perform reflash if available

5

Step 5: If issue persists after programming, test ECM communication circuits and consider ECM replacement if hardware fault is confirmed
