ECM Reprogramming
| • | Engine Oil Life Remaining--When available, use a scan tool to reset the Engine Oil Life Remaining back to the original percentage recorded before the module was reprogrammed. |
| | Important: After programming, perform the following to avoid future misdiagnosis:
|
| • | Turn the ignition OFF for 30 seconds. |
| • | Turn the ignition ON with the engine OFF. |
