Starter Relay Circuit Short to Battery (P061512)
DESCRIPTION
While the engine is being cranked, positive battery voltage is applied to terminal
STA of the ECM. If the ECM detects the starter control (STA) signal while the vehicle
is being driven, it determines that there is a malfunction in the STA circuit. The
ECM then illuminates the MIL ...
