Shift solenoid (DSL) is controlled by ECM to control hydraulic pressure acting on lock-up relay valve, which controls torque converter clutch lock-up. DTC will set if ECM detects an open or short circuit when solenoid resistance is 8 ohms or less with solenoid energized, or 100 k/ohms or more with solenoid not energized. If ECM detects a malfunction, shift solenoid (DSL) is turned off. Possible causes are:
- Open or short in solenoid circuit.
- Shift solenoid malfunction.
- ECM malfunction.
