CRUISE CONTROL CASSETTE - CAUTIONS
The cruise control cassette is mounted on the steering column directly behind the steering wheel. It contains a spiral tape that connects the switches on the steering wheel to the cruise control circuit.
Prior to installation on the vehicle, the cassette is set at its mid-point position, i.e., from the mid-point position the cassette can be rotated the same number of revolutions in each direction. Replacement cassettes from the Parts Department are preset at mid-point as well.
The cassette contains sufficient tape to accommodate lock to lock turning of the steering wheel. Further cassette rotation can break or fold the tape. For this reason the cassette mid-position must correspond to the steering wheel straight ahead position to avoid tape damage.
When working on Range Rover steering, the following precautions must be taken:
1. If centering the steering wheel alters it from its original position, the cassette must be corrected by the same amount and direction as the steering wheel.
EXAMPLE: If the steering wheel required half a turn in the counter-clockwise direction to correct it to the straight ahead position, then the cassette must also be rotated counter-clockwise through half a turn before refitting the wheel.
2. When fitting the steering wheel, ensure that the lugs on the cassette are correctly located in the holes in the back of the steering wheel.
3. Great care should be taken if the steering shaft is disconnected from the steering box. If the disconnected steering column is allowed to spin freely through several revolutions, the cassette mid-point position may be lost resulting in tape breakage when the steering system is reconnected.
If the cassette mid-point is lost, resetting should be carried out as follows:
^ Hold cassette with steering wheel locating lugs facing upward.
^ Wind cassette counter-clockwise as far as possible.
^ Rewind clockwise two full turns.
If tape resetting has been carried out, the reassembled cruise control system must be tested by winding the steering from lock to lock ten times followed by a check of all cruise control functions.
