Yukon Denali AWD V8-6.2L (2007)
It is important that you first identify the calibration number that is in the SDM. This can be done using the Tech 2(R) and requesting module ID.
The calibration number will determine if the SDM calibration can be updated or if the SDM will need to be replaced before the new calibration
can be installed. Use the table's shown to identify the proper corrective action that is required.
If the vehicle has one of the current production calibrations listed below, DO NOT replace the SDM and DO NOT reprogram. If a problem still
exists, it is not caused by a calibration error. Use normal diagnostics to correct the condition.
The new calibrations are currently available in TIS version 6.0 (or later) or on TIS2WEB.
