The (VECU) Vehicle Electronic Control Unit supplies and monitors the cranking signal to the starter motor relay. Several types of starter cranking protection are provided so the starter cannot be engaged in unwanted conditions. The starter cranking protection will also limit the maximum cranking time to 18 seconds without cycling the key.

Probable cause
1) Starter motor relay (K65)
2) Wire between Engine Control Module (ECM) and starter motor relay
