Reprogramming of ACC control module |
Cars affected |
All cars with ACC from M98-00 up to and including VIN Y3017122.
Background |
When the ACC control unit autocalibrates, the display first lights up brightly and then goes out. The display then shows 0 or 0-HI and the ventilation fan stops for about 30 seconds. Sometimes the code 0-22 or 1-22 is shown on the display.
After customer complaint, a new software version should be loaded using the diagnostic tool.
Parts required |
Use the software on the CD enclosed: Saab TIS 2000, SPS Version 5.1 Tech II version 35.000.
The information on this CD will also be available on the next edition of WIS.
Procedure |
• |
Load the new ACC control module software using the diagnostic tool.
Once the ACC control module software has been loaded, little of the autocalibration will be shown. The ACC control module will autocalibrate in the background, and therefore autocalibration will be less of a disturbance to the customer. Calibration is indicated by the display flashing for approximately 1 second. The display shows the most recent setting and the fan speed is simultaneously lowered two steps. After calibration is complete, the ACC control module returns the system to the setting used prior to calibration. |
• |
Explain to the customer that it is totally normal for the system to require autocalibration.
