Cruise Cable Play Inspection and Adjustment
INSPECTION AND ADJUSTMENT
1) Remove actuator cap.
2) With actuator lever (1) returned at original position (2)
(Where lever does not move clockwise any further), check
cruise cable for play.
If it is out of specification, adjust it as follows
Cruise Cable play “a” :
1 – 2 mm (0.04 – 0.08 in.)
3) Loosen cable lock nut (3).
4) Adjust cable play to specified value by turning adjusting nut
(4).
5) Tighten lock nut (3) securely after adjustment.
On-Vehicle Service
Cruise Main Switch
REMOVAL
1) Disconnect negative (–) cable at battery.
2) Remove meter cluster hood (1) by removing its mounting
screws (2).
3) Remove cruise main switch (3) from instrument panel.
4) Disconnect connector from cruise main switch (3).
INSPECTION
