DTC Inspection

NOTE:
  • When there is a malfunction in the immobilizer system, DTCs are recorded in the start stop unit and PCM.
  • The DTCs stored in the start stop unit can be verified using the flashing pattern of the security indicator light and M-MDS.
  • If immobilizer system related DTCs are not recorded even if the engine cannot be started, perform symptom troubleshooting. (See NO. 3 WILL NOT CRANK [SKYACTIV-G 2.0] .)
