Flow of Diagnosis

NOTE:
- If any concerns are noted with the speedometer or horn, address those concerns by referring to their associated system before continuing speed control diagnosis.
- When in speed control mode, initial depression of the clutch pedal may cause a normal momentary increase of engine rpm.

1. Verify the customer concern by operating the speed control system.
2. Visually inspect for obvious signs of mechanical and electrical damage.
