Monitor Description

This DTC indicates an open or short in the shift solenoid valve SL1, 2, 3, 4 and 5 circuit. The TCM 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 TCM detects the problem, illuminates the MIL and stores the DTC. Also, the TCM performs the fail-safe function and turns the other normal shift solenoid valves ON/OFF. In case of an open or short circuit, the TCM stops sending the current to the open or short circuited solenoid.
