SI83.40-P-0004GH | Service information: Software change in pushbutton control module AAC | 5.11.03 |
MODEL 163.113 /128 /157 /174 /175 #A as of 458810
This information is to inform you of a software change to the pushbutton control module AAC (N22).
As of Model Year 2004 (VIN A458810), the speed of the rear blower motor (M2/1) cannot be increased beyond the setting for the front blower (A32m1).
The rear blower controls (N72/2s3) can be actuated higher than the fan speed for the front blower motor. The LED indicators will also show a higher fan speed. However, the speed of the rear fan will NOT be higher than that of the front.
This function is NOT a failure, and will be described in the B2004 release of the Operator's Manual.
