Honda Odyssey cruise control
2000 Odyssey, 61,000m. Cruise control started "dropping out"
occasionally at first, now regularly. Dealer mechanic is about to replace brake switch because "it is noisy" and the under-hood actuator. Looking carefully at wiring diagram page 4-34 in shop manual it doesn't appear that there is any "feedback" between the actuator (motor and clutch) and the cruise control unit and therefore the ccu cannot know whether the actuator has actually moved the throttle. Pin 10 of the ccu lights the cruise control light in the instrument cluster and this goes out when the cruise control fails. It seems to me that the problem is more likely in the ccu than the actuator, even an intermittently contacting brake light switch would allow cruise restoration. Dick |

A noisy switch will cause it to drop out. It won't reset itself. You have to
start it back up. The feedback from the motor will be through the throttle position sensor but that shouldn't drop it out. Replacing both is just a money grabbing scheme. Replace the switch first and then move on if there is still a problem. "Dick" > wrote in message ... > 2000 Odyssey, 61,000m.

Normally if the brake pedal is touched the cruise control drops out but can be restored by pressing accel/resume on the steering wheel spoke. In my case however cruise will not resume though occasionally turning the dashboard cruise control switch off then on again will allow a new setting of speed via set/decel. I assume the mechanic meant the switch sounds noisy not that he saw intermittancy in the closure/opening. I e-mailed the service advisor my posted argument and that I didn't want to pay for an unneeded actuator and he assured me that if replacing it didn't solve the problem both the purchase price and installation charge would be struck from my invoice, I have a printed copy of the exchange.

I feel sorry for you people that have to be spoon fed by the dealer for such
simple problems. The dealer stated it was noisy because 99.99999% of the time that is the problem. It is a cheap part and takes very little knowledge and time to replace it. You could also buy it cheap from one of the online Honda parts supplier and have the corner mechanic replace it rather than pay the high price at the dealer.
