Speed Control Switches
| Item Number | Description |
|---|---|
| 1 | Set speed adjustment |
| 2 | Cancel switch |
| 3 | Resume switch |
There are three speed control switches:
- Speed adjustment
- Cancel
- Resume
The speed control switches are located on the RH (Right-hand) side of the steering wheel. The switches are connected via fly leads to the clock spring. The speed control switches are resistive ladder type switches which vary the resistance of a 5 volt signal sent to them. The signal is returned along a Lin bus to the instrument cluster. The instrument cluster routes the control signals to the ECM on the MS CAN.
Speed control is engaged by rotating the speed adjustment switch to the + or - positions. Once engaged the speed can be varied by the speed adjustment switches. Each press of the speed adjustment switch will increase or decrease the set speed in steps of 1 mph (2 kph).
