How do you reset computer on 2003 Chevrolet Venture?

Answer 1

I don't know specifically about your vehicle, but you can reset the computer on most (maybe all) cars by doing this:

• Disconnect the negative battery cable.
• Press on the brake for 15 seconds
• Try to honk the horn. If it honks, hold it down until it quits.
• If the horn continues to blow disconnect the positive battery cable and try the steps above again. If the horn still doesn't stop you have have a strange system and this method won't work.
• Once the horn won't blow, wait three minutes and reconnect the battery cable(s).
• Your computer should be reset.
