On Board Diagnosis LogicBCS001H0
Diagnostic trouble code “P0615 STARTER RELAY/CIRC” with CONSULT-II is detected when starter relay
switched ON other than at “P” or “N” position. (Or when switched OFF at “P” or “N” position).
Possible CauseBCS001H1

Harness or connectors
(Starter relay and TCM circuit is open or shorted.)
