CRUISE CONTROL CABLE ADJUSTMENT PROCEDURE
DESCRIPTION
This bulletin describes the procedure for adjusting the cruise control system cables, and should be used as a supplement to the cruise control information in the Engine Electrical System section of the shop manual.
DISCUSSION
The objective of cable adjustment is to correctly adjust the play (or slack) in the system's cables. It should be noted that some play is necessary for proper system operation.
Excessive play in the cables can result in complaints that it takes too long to engage or cruise control surge (on/off application of throttle).
Insufficient play in the system's cables can result in the throttle being held partially open, causing a higher than desired base idle speed.
The diagrams illustrate the component identifiers used in this bulletin.
As can be seen from the diagram:
- Pulley A is connected to the accelerator cable.
- Pulley B is connected to the throttle cable.
- Pulley C is connected to the cruise control cable.
PROCEDURE
The following procedure should be performed when the engine is warm (coolant temperature above 80 degrees C).
1. Check that there are no sharp bends or breaks in the accelerator, throttle, or cruise control cables.
2. Remove the cover of the pulley assembly by loosening the two screws on the top of the pulley assembly.
3. ACCELERATOR CABLE ADJUSTMENT Loosen lock nut A sufficiently to allow cable adjustment. Turn adjusting nut A until pulley B just begins to move away from the pulley C contact. Then, turn adjusting nut A in the opposite direction approximately 1/2 turn. The accelerator cable play (inner cable to cable housing movement measurement) should be 1-2 mm (.04-.08 in.). Tighten lock nut A and verify accelerator cable play.
4. THROTTLE CABLE ADJUSTMENT Loosen lock nut B sufficiently to allow cable adjustment. Turn adjusting nut B until the throttle lever stopper begins to move away from the idle position switch. Then, turn adjusting nut B in the opposite direction approximately 1 turn. The throttle cable play (inner cable) should be 2-3 mm (.08-.12 in). Tighten lock nut B and verify cable play. Visually verify that the throttle lever stopper completely depresses the idle switch plunger.
5. CRUISE CONTROL CABLE ADJUSTMENT Loosen lock nut C sufficiently to allow cable adjustment. Turn adjusting nut C until pulley C begins to move away from its stopper. Then, turn adjusting nut C in the opposite direction approximately 1/2 turn. The accelerator cable play (inner cable) should be 1-2 mm (.04-.08 in.). Tighten lock nut C and verify inner cable play.
6. With the engine off, verify the wide open throttle (WOT) position by depressing the accelerator pedal completely.
7. Release the accelerator pedal and again verify that the throttle lever stopper completely depresses the idle switch plunger.
8. Test drive the vehicle to verify proper cruise control operation.
9. Verify that the base idle speed is within specification using the procedure in the Service Adjustment Procedures section of the shop manual.
10. Replace the pulley assembly cover.
