(See CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW.)

^*2

(See DTC Inspection Note.)

Action for Non-repeatable Malfunction

• If the malfunction does not recur, verify the malfunction cause by performing the following actions:

• Verify that a DTC has been recorded in the memory. (See DTC INSPECTION [START STOP UNIT].)

• Based on the repair order form, attempt to drive the vehicle or perform tests to replicate the malfunction, record the data at that time, and detect the malfunction cause.

• Shake the wiring harness or connector of the electrical component which is suspected to be the cause of the malfunction, and inspect for malfunction or occurrence of any DTCs.

  

• Inspect the female terminals on the connector of the electric component which is suspected to be the cause of the malfunction for poor connection.

  

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].)
