DTC U1282: Keyless Access Control Unit Lost Communication With Driver's MICU

NOTE: If you are troubleshooting multiple DTCs, be sure to follow the instructions in B- CAN System Diagnosis Test Mode A (see TROUBLESHOOTING - B- CAN SYSTEM DIAGNOSIS TEST MODE A ).
  1. Clear the DTCs with the HDS.
  2. Press the engine start/stop button to select the OFF, ACC, and ON mode.
  3. Wait for 6 seconds or more.
  4. Check for DTCs with the HDS.

    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.
