. DTC CODE DTC DETECTION CONDITION TROUBLE AREA P0748 The ECM checks for an open or short in the shift solenoid valve SL1 circuit while driving and shifting between 4th and 5th gear (1 trip detection logic) Output signal duty equals to 100% HINT: SL1 output signal duty is less than 100% under normal condition Open or short in shift solenoid valve SL1 circuit Shift solenoid valve SL1 ECM MONITOR DESCRIPTION This DTC indicates an open or short in the shift solenoid valve SL1 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 between 4th and 5th gears, if the ECM detects an open or short in the shift solenoid valve SL1 circuit, the ECM determines that there is a malfunction
