DESCRIPTION Shifting from
1st to 6th is performed in combination with the ON and OFF operation of
the shift solenoid valves SL1, SL2, S1, S2, S3, S4 and SR, which are
controlled by the ECM. If an open or short circuit occurs in the shift
solenoid valves, the ECM controls the remaining normal shift solenoid
valves to allow the vehicle to be operated safely (See page
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 function and turns the other normal shift solenoid valves ON/OFF. In case of an open or short circuit, the ECM stops sending current to the open or short-circuited solenoid. 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
