   • Yes: Check the CAN communication line. Refer to DTC U1000 CAN COMMUNICATION LINE .
   • No: GO TO  4.
4. CHECK O/D OFF INDICATOR LAMP CIRCUIT 
   1. Turn ignition switch to "OFF" position.
   2. Check the combination meter.

      Refer to COMBINATION METER .

   OK or NG 

   • OK: GO TO  5.
   • NG: Replace the combination meter.
5. CHECK SYMPTOM 

   Check again.

   OK or NG
