Description
The shift solenoid valve dsl is turned on and off by signals from the ecm to control the hydraulic pressure acting on the lock-up relay valve, which then controls operation of the lock-up clutch.
Fail-safe function: if the ecm detects a malfunction, it turns the shift solenoid valve dsl off.
Monitor description
Torque converter lock-up is controlled by the ecm based on engine rpm, engine load, engine temperature, vehicle speed, transmission temperature, and shift position selection. The ecm determines the lock-up status of the torque converter by comparing the engine rpm (ne) to the input rpm (nt). The ecm calculates the actual transmission gear by comparing the input rpm (nt) to the output rpm (sp2).
When conditions are appropriate, the ecm requests "lock-up" by applying control voltage to the shift solenoid valve dsl. When the shift solenoid valve dsl is opened, the shift solenoid valve dsl applies pressure to the lock-up relay valve and locks the torque converter clutch. If the ecm detects an open or short in the shift solenoid valve dsl circuit, the ecm interprets this as a fault in the shift solenoid valve dsl or its circuit. The ecm will illuminate the mil and store a dtc.
