Speed control system (tempostat) — general information and testing (Honda Accord 6)

1. The cruise control automatically maintains the selected cruising speed of the vehicle. The cruise control servomotor is located in the engine compartment, secured to the left on the rear bulkhead (on V6 models - to the right) and connected to the throttle rod by a cable. The main components of the system are the servomotor, the brake light switch (on models with a manual transmission - the starter circuit disconnect switch), control switches, speed sensors and actuator relays. Checking individual functions of the system requires the use of special diagnostic equipment, and its implementation is beyond the skill level of the average amateur mechanic. Below is a description of only the most general check procedures that allow you to identify the causes of the most typical cruise control failures.

2. Locate the cruise control fuse and check its condition (see Section Fuses - General Information).

3. The brake light switch (or brake pedal position [BPP] switch) should operate when the foot brake pedal is depressed, disengaging the cruise control. Have an assistant depress the brake pedal and check that the brake lights operate properly.

4. If the brake lights do not respond to pressing the pedal, find out the reason for the failure and repeat the check of the cruise control function.

5. Check the condition of the drive cable running from the servo/crankshaft speed control assembly to the throttle linkage. Replace any damaged or worn cable.
