l. Multiplex tilt and telescopic ECU*3 5. DIAGNOSTIC CODES FOR CAN COMMUNICATION SYSTEM a. DTCs for the CAN communication system are as follows: U0073, U0100, U0101, U0114, U0123, U0124, U0126, U0129, U0199, U0208, U1002, U1115, B1499, and B2621 6. NOTES REGARDING TROUBLESHOOTING a.

DTCs regarding the CAN communication system can be checked using the intelligent tester. c. The CAN communication system cannot detect trouble in the branch line of the DLC3 even though the DLC3 is also connected to the CAN communication system. 7. HOW TO DISTINGUISH CAN J/C CONNECTOR a. In the CAN communication system, the shape of all connectors connected to the CAN J/C is the same. The connectors connected to the CAN J/C can be distinguished by the colors of the bus line HINT: See TERMINALS OF ECU for bus line color or the type of connecting surface. HOW TO PROCEED WITH TROUBLESHOOTING HINT: DTCs for the CAN communication system are as follows: U0073, U0100, U0101, U0114, U0123, Refer to the troubleshooting procedures of each system if DTCs regarding the CAN communication Before measuring the resistance, leave the vehicle for at least 1 minute and do not operate the ignition HINT: Operating the ignition switch, any switches or any doors triggers related ECU and sensor communication *: Use the Techstream. 1.
