2003 Honda Odyssey Service and Repair Manual

Known issues on the 2003 Odyssey. Fifteen recalls are on federal record for this model year, the majority tied to Takata-brand frontal air bag inflators on both the driver and passenger side, where propellant degradation or manufacturing variability can cause the inflator to rupture and send metal fragments into the cabin during deployment. Separately, the ignition switch interlock lever can deform and let the key be removed without the automatic transmission being shifted into park, allowing the vehicle to roll away; the automatic transmission's countershaft and secondary shaft second gears can build up heat and chip or break, risking transmission lockup; and some fuel tanks have surface imperfections that can let fuel leak out near an ignition source. Owners have filed 940 complaints for the year. The factory diagnostic and repair procedures behind each of those systems are here.

Whether you're pulling a driver or passenger air bag module, tracing an ignition switch fault, or servicing the automatic transmission, it keeps you on the OEM procedure and the correct specification for your specific 2003 Odyssey.
