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].)
