The automatic transmission supplies power to the solenoid valves by way of a control relay. When the Powertrain Control Module (PCM) sets the relay to ON, the relay operates, and the battery power is supplied to all the solenoid valves. When the PCM sets the relay to OFF, all solenoid valve power is shut off and the transmission is held in the 3rd gear position. (Fail Safe Mode). The PCM checks the A/T control relay signal by monitoring the control signal. If the voltage applied to A/T solenoids is lower than 0.5V, the PCM sets this Diagnostic Trouble Code (DTC).
