. DTC CODE DTC DETECTION CONDITION TROUBLE AREA P0778 The ECM checks for an open or short in the shift solenoid valve SL2 circuit while driving and shifting gears (1-trip detection logic). Output signal duty equals 100%. HINT: SL2 output signal duty is less than 100% under normal conditions. Open or short in shift solenoid valve SL2 circuit Shift solenoid valve SL2 ECM MONITOR DESCRIPTION This DTC indicates an open or short in the shift solenoid valve SL2 circuit. The ECM commands gear shifts by turning the shift solenoid valves ON/OFF. 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. Also, the ECM performs the fail-safe While driving and shifting gears, if the ECM detects an open or short in the shift solenoid valve SL2 circuit, the ECM determines there is a malfunction
