P0602-Control Module Programming Error/Not Programmed: Notes

For a complete wiring diagram  , refer to appropriate SYSTEM WIRING DIAGRAMS article.

The controller is programmed during manufacturing with generic software to facilitate testing. However, generic software does not have the proper calibrations to control a transmission in a vehicle. The check for generic software is made at power-up. If generic software is found, the MIL will light immediately and the MIL will stay on even if the fault is cleared, until the proper software is installed. 

• When Monitored: 

  Check for generic software is made at power-up 

• Set Condition: 

  If generic software is found, the MIL will light immediately. This DTC is designed to inform the technician that the controller still has generic software installed. 

Always perform the PRE-DIAGNOSTIC TROUBLESHOOTING PROCEDURE before proceeding.
