Injector Classification Procedure
NOTE:
The engine must not be running for this procedure.
NOTE:
If installing a new injector, make a note of the seven digit alphanumeric code. You will need to enter it into the scan tool during the Injector Quantity Adjustment procedure.
NOTE:
Before performing this procedure, if the PCM has been replaced, or if any injector has been installed anywhere but its original location, make a note of the seven digit alphanumeric codes and the physical location of each injector. You will need to enter them into the scan tool during the Injector Quantity Adjustment procedure.
- Turn the ignition switch "ON".
- Using a scantool, select the PCM View, then MISCELLANEOUS FUNCTIONS.
- Select the Injector Quantity Adjustment, then NEXT.
- If the PCM was replaced, the Injector EEPROM Location procedure must be performed. Select YES, then NEXT, and follow the directions on the scan tool. Otherwise, go to step 5.
- Select the injector(s) that has been replaced, access the keyboard function, and type the seven digit alphanumeric code next to the cylinder number that corresponds to the physical location where the injector has been installed.
- Click NEXT. The scan tool will prompt to turn the ignition switch off for 12 seconds.
- Repeat step 5 and 6 for any other injectors that are new, or have been moved from their original location. Once injectors are classified, cycle ignition to complete.
- Once the seven digit alphanumeric codes for all injectors have been entered into the PCM, cycle ignition to complete the procedure.
