      Tech Tips

      After turning the engine switch from off to on (IG), wait 10 seconds or more before checking for DTCs.


      Body Electrical > IPA/ICS/Clearance Sonar > Trouble Codes

    2. Clear the DTCs according to the screen on the GTS.

      Click here


      Body Electrical > IPA/ICS/Clearance Sonar > Clear DTCs

    3. Recheck for DTCs.

      Body Electrical > IPA/ICS/Clearance Sonar > Trouble Codes
      OK
      No DTCs are output.

      Tech Tips


      • If CAN communication system DTCs are stored, they may also be stored in other systems.

      • If the CAN communication system has been inspected and repaired in other systems, the DTCs will not be output when rechecking for DTCs.

      • If these DTCs are output frequently, duplicate the conditions that caused the problem symptoms and perform the inspection again, even though DTCs were not output when rechecking for DTCs.
