Is DTC U1282 indicated?
YES -Go to the driver's MICU input test, and do all power, ground/and communication input tests (see MICU INPUT TEST ). If the tests prove OK, replace the driver's under-dash fuse/relay box (see DRIVER'S UNDER-DASH FUSE/RELAY BOX (MICU) REMOVAL AND INSTALLATION ). If the DTC is still present, replace the keyless access control unit (see KEYLESS ACCESS CONTROL UNIT ).
NO -Intermittent failure, the system is OK at this time. Check for loose or poor connections between the keyless access control unit and the driver's MICU.
