2004 Honda Odyssey Service and Repair Manual

Known issues on the 2004 Odyssey. Thirteen recalls are on federal record for this model year, most of them tied to the Takata frontal airbag inflators: propellant that degrades after long-term heat and humidity exposure can cause the driver- or passenger-side inflator to rupture on deployment, throwing metal fragments at occupants and risking serious injury or death, with a related campaign covering a passenger airbag that may have been installed incorrectly. A separate pair of recalls covers an air bag control module that can misread electrical noise and trigger the front and side air bags and seatbelt pretensioners with no crash involved. Beyond the air bag system, Honda recalled the ignition switch interlock lever, which can deform and let the key be removed without the automatic transmission in park, allowing the vehicle to roll away; the fuel pump, which can corrode at an electrical terminal and stall the engine without warning; and the automatic transmission, where heat buildup between the countershaft and secondary shaft second gears can chip or break gear teeth and lock the transmission up. Owners have filed 584 complaints for the year; no technical service bulletins are logged for the 2004 Odyssey. The factory diagnostic and repair procedures behind every one of those systems are here.
From an air bag inflator inspection to chasing a rollaway condition, a stalling fuel pump, or a slipping transmission, it keeps you on the OEM procedure and the correct specification for your specific 2004 Odyssey.
ON CERTAIN MINIVANS, THE FUEL PUMP MAY FAIL DUE TO CORROSION OF AN ELECTRICAL TERMINAL.
IF THE PUMP STOPS WORKING, EHT ENGINE WILL STALL WITHOUT WARNING, AND A CRASH COULD OCCUR.
