Diagnostic Trouble Code Chart

HINT:

• If CAN communication system DTCs are output, trouble cannot be determined only by the DTCs. Perform troubleshooting according to "HOW TO PROCEED WITH TROUBLESHOOTING" (see HOW TO PROCEED WITH TROUBLESHOOTING  ).

1. ECM

   HINT:

   • DTC communication uses the CAN communication system.
   • Distance control ECU data is also output.
