When servicing the vehicle with the VIN you entered, the following diagnosis might be helpful if the vehicle exhibits the described symptoms.
Dealers may comment that the odometer has reset to "0" after the battery has been disconnected.
Reprogram the IPC using the new service calibration, which was available from Techline starting July 14, 2003 on the TIS2000 version 7.5 or later. This calibration is an electronic calibration and is not available from GMSPO. The Tech 2 must also contain software version 23.003 or later available from Techline starting July 2003.
Important: If the odometer had over 50 miles, it will have to be sent to an A/C Delco Service Center to have the mileage reset.
