My buddy has a Honda and it has the "maintenance required" light and check engine light. he knows what the problem is with the check engine light but not the maint. req'. now i have a Camaro and i know to clear my code lights i have to put the key to power and press the gas 3 times and my lights turn off. how do you do that with the 04 Honda Civic? i don't have a reader so i cant clear them that way. Please let me know! Thanks
