Fault code 49 is -- The Motor Controller module has measured a voltage from the valve diagnostic
circuit that indicates the cold valve is faulty. The most likely cause is that the valve wiring harness has not been connected correctly or the valve is open circuit. Check wiring plug is connected properly to the cold valve & the pins inside the valve wiring plug are not bent & are making good contact. Next check cold valve solenoid coil for continuity & a resistance of 64 ohms. If wiring & coil is ok then it may be a motor controller fault.
