PROCEDURE


  1. CHECK FOR DTC


    1. Using the GTS, check for DTCs according to the prompts on the screen.

      Tech Tips

      After turning the power 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.


      Body Electrical > IPA/ICS/Clearance Sonar > Clear DTCs
    3. Recheck for DTCs.


      Body Electrical > IPA/ICS/Clearance Sonar > Trouble Codes
      OK
      DTC U0073, U0100, U0124, U0126, U0129, U0140, U0155, U0164 is not 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.
