CRUISE CONTROL SYSTEM (DIAGNOSTICS)

GENERAL DESCRIPTION

C: INSPECTION

1. BATTERY

Measure battery voltage and specific gravity of
electrolyte.

Standard voltage:

12 V, or more

Specific gravity:

Above 1.260

2. CRUISE CONTROL CABLE

Check the cruise control cable (B) installation.
If NG, install the cable securely.

3. ACCELERATOR CABLE

Check movement of the accelerator cable (A) when
the cruise control throttle is moved by hand.
If NG, check throttle cam.

4. THROTTLE CAM

Check that the throttle cam moves smoothly.
If NG, repair throttle cam.

5. CABLE FREE PLAY

Check that the clearance (A) between throttle cam
(B) and lever or cable deflection (D) is within spec-
ifications.

Throttle cam-to-lever clearance:

0 — 1 mm (0 — 0.04 in)

Inner cable deflection:

1 — 8 mm (0.04 — 0.31 in)

If NG, adjust the clearance or the deflection with
the adjust nut.

NOTE:
Check that the cap (C) is positioned in the groove.
