Missing Offset and Gradient Values on the Transfer Case
Information
Missing offset and gradient values on the transfer case
When you replace the all-wheel drive control unit or the transfer case (with the all-wheel drive control unit), the offset and gradient values (referred to below as classification data) must be written into the new all-wheel drive control unit.
The absence of classification data in the all-wheel drive control unit will result in poor vehicle driveability.
Since the classification data always relates to and is matched to the transfer gear, it is engraved on the transfer case; ⇒ Figure 1 shows 15 as the gradient value and 05 as the offset value.
