HINT:
When warning lights continue to blink, a ground short in the wiring of terminal TC of the DLC3 or an internal ground short in one or more ECUs is suspected.

INSPECTION PROCEDURE

HINT:
Check the condition of each related circuit connector before troubleshooting (CAMRY_ACV40 RM000000UZ301ZX.html).
1.CHECK CAN COMMUNICATION SYSTEM

  1. Check if a CAN communication DTC is output (CAMRY_ACV40 RM000001JB800HX.html).
