Also, the ECM stops sending current to the open or short-circuited solenoid
. DTC CODE DTC DETECTION CONDITION TROUBLE AREA P0985 ECM detects a short in the solenoid valve SR circuit 2 times when solenoid valve SR is operated (1-trip detection logic). Short in shift solenoid valve SR circuit Shift solenoid valve SR ECM P0986 ECM detects an open in the solenoid valve SR circuit 2 times when solenoid valve SR is not operated (1-trip detection logic). Open in shift solenoid valve SR circuit Shift solenoid valve SR ECM MONITOR DESCRIPTION These DTCs indicate an open or short in the shift solenoid valve SR circuit. When there is an open or short circuit in any shift solenoid valve circuit, the ECM detects the problem, illuminates the MIL and stores the DTC. When the shift solenoid valve SR is ON, if its resistance is 8 Ω or less, the ECM determines there is a short in the shift solenoid valve SR circuit. When the shift solenoid valve SR is OFF, if its resistance is 100 kΩ or more, the ECM determines there is an open in the shift solenoid valve SR circuit
