Lock-Up Solenoid (Sidekick A/T)

When ECM senses conditions are correct for energizing lock-up solenoid in automatic transmission, ECM will energize lock-up relay. Relay, in turn, energizes lock-up solenoid. When energized, the lock-up solenoid provides a feedback signal to ECM, indicating lock-up signal has been received. This is not a true indication that physical lock-up has occurred.
