WINTER shifting programme
|
In order to make it easier to pull away in icy road conditions there is a WINTER gear change programme. If the WINTER programme is selected and the selector lever is in position D the vehicle will pull away in 3rd gear and thereafter change up normally to 4th and 5th gear.
With the selector lever in position 3 only 3rd gear will be used.
A switch button located on the gear selector console makes it possible to choose between the WINTER and NORMAL gear change programmes.
The switch button has two connections, one to the control module pin 7 (A) and the other to the grounding point G41S. The control module supplies B+ on pin 7 (A). When the button is depressed the circuit is grounded and a change between the WINTER and NORMAL programmes occurs.
The TCM sends information on the current mode as bus information WINTER, unit ON/OFF. In connection with bus information “WINTER ON”, the main instrument unit turns on the WINTER indicator lamp.
WINTER programme functions in the different selector lever positions:
