the abs light could be the rear wheel speed sensor wire harness broken i have seen that alot.the other problem might be the idle is the cel on.i would recommend selling that passport sorry to tell you this if you don't know the passport is the same as the isuzu rodeo the passport is not built by honda its a rodeo with an h badge honda wanted an suv and had not built the pilot yet so thy made a bad deal with isuzu.the passports are problems some run for ever some burn to the ground.
