Flow of Diagnosis

NOTE: If any concerns are noted with the speedometer, stoplamps, or horn, address those concerns by referring to their associated system before continuing speed control diagnosis.

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