To correct this condition, the ECM should be reprogrammed using the GDS download as described in this bulletin. For confirmation that the latest reflash has been done to a vehicle you are working on, verify ROM ID using the tables in this TSB.
- P0263: Cylinder1 Contribution/Balance
- P0266: Cylinder2 Contribution/Balance
- P0269: Cylinder3 Contribution/Balance
- P0272: Cylinder4 Contribution/Balance

- A fully charged battery is necessary before ECM upgrade can take place. It is recommended that the Midtronics GR8-1299 system be used in ECM mode during charging. DO NOT connect any other battery charger to the vehicle during ECM upgrade.
- All ECM upgrades must be done with the ignition key in the ‘ON’
- Be careful not to disconnect any cables connected to the vehicle or GDS during the ECM upgrade
- DO NOT start the engine during ECM
- DO NOT turn the ignition key ‘OFF’ or interrupt the power supply during ECM
- When the ECM upgrade is completed, turn the ignition ‘OFF’ and wait 20 seconds before starting the ONLY use approved ECM upgrade software designated for the correct model, year.
